TSB 18-036-06 is AWESOME!!!

[ThinkMud]

I had my oil changed this morning and also complained about my few electrical problems, like the radio cutting off at low RPM's, a few crazy dash lights going on then off. I complained so that they would flash my chip, b/c of the TSB about it, and it is soooooooooooooooooo worth it!!! my JK unlimited has 33" tires, 3.21 gears and is 6 sp...

Before the flash:
Ran ok, never felt like i had enough power, was very slugish off the line, very slugesh at any rmp under about 2.8k Would stall a lot. very slow and slugish response when i give it gas..

After the flash:
Runs like a completely different vehicle!!
no slugishness, very responsive, not really more power, just more constant power, it seems i can keep from down shifting a tad more now, like some turns in my neighborhood, where i'd used to have to drop down to 1st to hit, now i can take in 2nd easily, and i even made one in 3rd with out it studdering.

I am so glad I got this done! if anyone has a JK built b4 Nov. 10th, they should have it flashed, it is a huge difference in how it rides, shifts, ecelerates etc... i'm so stoked!

[jonz]

What does flashing consist of? Is it reprograming the computer to a different setting? My 6 speed Sahara has power but I think there is a slight lag part of the time. Excelleration doesn't seem consistant. Do you think I have your same problem? My gas mileage has been good. Around 20 MPG.

[ThinkMud]

The TSB is from here http://www.alldata.com/tsb/Chrysler/1163836800000_1164182400000_18-036-06/index.html

it is 4 pages long. they basically hook your computer up and put updated software on it. if your rig was made b4 Nov. 10th, then you need this.

It did help with that inconsistent throttle response.

I'm not saying it give more power (although it may) i'm just saying it improves the performance greatly. much smoother now, as in more consistent gas getting to the engine. I couldn't be happier.

And if you are getting 20mpg, that is awesome!! I was getting around 15mpg b4 the flash, but i have larger much heavier rims and tires on, and no AirDam. and two big empty holes where my fog lights should be(I bought Kilby's stock rubicon bumper with no foglights so i could get the tow hooks).

hope that helps! and it can't hurt to get the updated software installed.

[doojer]

Wow. That sounds like a huge difference... I picked up my JK in late September, so I might give this a whirl even though I don't have many of the problems that you seemed to be experiencing. Thanks for the tip! :D

BTW, do they do this stuff automatically when you have a Jeep serviced at the dealer, or do you have to specifically say you're having problems?

[ThinkMud]

I had to give them the TSB, i just printed it out and took it in, and also i had to say my battery light came on and stuff. So no they don't do it automatically, you have to say you have the symptoms listed on the TSB (hence me telling them my battery light came on). The flash is to solve problems, like the electrical ones, but the software itself has been updated, and that is what changes the response and stuff. but they would rather not have to spend the time if it's not causing any "problems" they could care less if you rig runs better, haha... so just say you have had some crazy electrical problems and have had the battery light come on, and tell them that you think the TSB 18-036-06 should fix it.

[Jeephrog]

Not exactly sure when mine was built, but it was delivered to the dealer on Nov 17th. I'll have to check in a bit.

[Bill]

That sounds great, I need to look into it. I've had the radio cut out a couple of times and had an issue with stalling in the beginning which was a bit frustrating. I always thought it was strange that when I stalled, the ignition light never came on (or any of the other dash lights that come on when you first turn the key forward). Maybe it's part of the same problem?

Thanks for posting this!

[ericdewayne]

im in the exact same boat you are Bill, stalled a few times when i first got it, and the engine doesnt turn right away like it should when turning the key. It takes about a second or two for it to start to crank. I'll be going to the dealership soon.

[ericdewayne]

how long did it take for them to flash your puter?

[jckid]

YOBUCK,

Thank you for posting this information! I'm calling my dealer right away!

[fraynes1]

Took about 20-25 mins. for them to flash mine!

[doojer]

Took about 20-25 mins. for them to flash mine!Did you get the same reults as Yobuck?

[fraynes1]

Not sure, made it 10-12 blocks from the dealer when my wife went to roll up the window and the radio cut out and battery light came on.

I immediately went back and they flashed it. Were extremely embarrassed about it to boot!

Not sure what it was like before. Runs fine now, I have no complaints.

[BeerMonkey]

wonder if they even did it the first time? ill be telling my dealer about this when i go in for my first service

[ThinkMud]

Yeah it seems that some dealers are not too keen to jump to a flash, that is why you have to say something that happend on the TSB happend, so if you tell them your battery light came on and radio went out seems to do the trick;)

Hope this helps some people out, I drove mine to and from work today on the interstate, and it was still a huge difference, i'm very happy with it all over again, it's like getting a new JK for the 2nd time!

[jckid]

I am sooooo frustrated, so I have to share (vent!)!

I've been having some concerns with the shift quality of my automatic Unlimited. When I read about this TSB, and that it effects auto shift quality, I was so happy. I was sure I found my fix. My husband called up the local dealer right away to make an appointment. They didn't have an opening for two weeks, so he called the next closest dealer (40 miles away). They said that they thought it would definitely help, and they said that they could get it in right away.

So my husband took it out there today, only to be sent away with nothing being done. Here's the frustrating thing...they said that it's only for '07 Wranglers and Wrangler Unlimiteds (duh!). What a bunch of idiots! They work in a Jeep service facility and don't even know what an '07 Wrangler Unlimited looks like! You'd have thought the stickers that say "Wrangler Unlimited" on the side of my Jeep would be a clue to them! My Jeep was built prior to Nov. 10, so it is clearly included in the TSB. They then started to make excuses as to why they couldn't do it. Long story short, I think they simply had no clue what they were doing and they probably didn't have the most current, up to date software to run the flash.

So my husband drove 80 miles out of his way to take care of my baby, only to have his time completely wasted! Frustrating, for him and me! Well, needless to say, we'll be checking with the local dealer and see if they know what they're doing. We would have taken it to the dealer we bought it from, because they are great, but they are a 200 mile drive round trip.

Anyway, I thought you guys could probably feel my pain. I did call the Jeep Customer Service line to let them know what happened, so at least I got a little satisfaction from reporting their ignorance to the corporate office. :mad:

[BeerMonkey]

so he just left after they said you didnt have a 07?

[Robar]

Well, would you want technicians working on your JK if they didn't recognize it as a JK?

[tolh13]

maybe this thread should be moved to it looks like a hummer.

how about a poster for the dealership that shows silhouette of jeep and hummers!!!

[ThinkMud]

I feel your pain, and I am sorry you and your husband had to deal with this and are still without the TSB. My dealership had no clue the first time I talked to them, I had to print off the TSB and bring it in to them! But I agree with Robar on this, I wouldn't want a dealership working on my rig if they couldn't even tell by looking at it what it was!

Good luck with this and keep us posted! The TSB is worth it, even if you do have to wait a few weeks to get it.

[jckid]

I wouldn't want a dealership working on my rig if they couldn't even tell by looking at it what it was!


Exactly! That is why my husband just left. He figured if they didn't even know what kind of Jeep it is, he didn't want them touching it!

On his way home, my husband stopped in to the local dealer's service department to talk to them. They couldn't believe what happened at the other dealer. As it turns out, my husband has known the service advisor at the local dealership for years, so we are much more comfortable taking it there now. If we'd only known, we have taken it there in the first place. We have an appointement for next Thursday, so I'm crossing my fingers that everything goes smoothly. I'll post an update then.

[thrash]

Just had mine done, and am seeing the same benefits as ThinkMud. Used to have sluggish response from about 1700-2300 RPM. The vehicle is now MUCH more responsive in that range, and significantly smoother.

Time will tell if it helps with the occasional spasmodic fit that the ECM was having, where at low rpm under light throttle all the dashboard lights would illuminate, power would cease and then the ECM would recover and everything would go on as normal. Also occasionally accompanied by a radio reboot.

I hope those symptoms will also disappear. I'll update over time to let you all know.

[ThinkMud]

so far mine hasn't had any of the radio or dash lights issues. but I do now seem to have an issue with my headlights...

Twice now, i've turned my headlights off, got out, and noticed they were still on! the warning ding didn't sound, so the jeep thought they were off too, so i had to trun them on then back off again... it was weird...

jckid, glad to hear you have a better service place you trust!

[J33P JK]

Mine has done this a couple of times too, but they will turn off after a minute or so. Not sure why it does this, because it does not do it every time.

[ThinkMud]

Mine has done this a couple of times too, but they will turn off after a minute or so. Not sure why it does this, because it does not do it every time.

so maybe some how it's connected with the interior lights, that dim slowly after a while once you get out?

[thrash]

Mine have always done that. The lights remain on after I've shut the vehicle down, gotten out, and locked everything up. The inside lights dim almost immediately, and the headlights will auto-dim about 30-45 seconds later.

[ThinkMud]

That's crazy... maybe the flash made that happen too? I'll just let it be...

[jameswharton]

had the flash yesterday and it has stopped the battery light coming on and the radio cutout/popping so far. I can't really tell any drivability changes but it seems my miles are adding up faster per gas gauge position than they did before. No claims until I can test it for several tanks. I have been getting between 15 1/2 to 16 1/2 mpg and have 3600 miles on the clock. I have AEM Brute Force CAI, Magnaflow single in dual out Firebird muffler, stage II Jet performance module, 2 dr X, 6 speed with 4:10 gears. Best I ever got was one time 20 1/2 with a tail wind and 5 hr drive back from Dallas, freeway all the way. I sure hope this has helped my mileage, I am tired of reading about the 20 plus mile to the gallon folks on the forums. By the way, it is running strong, add ons made a performance difference but changed economy none.
Jim

[ThinkMud]

It should help your mpg, I too haven't checked yet, still on the first new tank, but it seems that i more miles per the gas mark then before, so i'm guessing it increased.. was getting around 14 to 15 mpg, now i'm hopeing at least 17, I will keep everyone updated.

[JeepDiver]

Mine has done this a couple of times too, but they will turn off after a minute or so. Not sure why it does this, because it does not do it every time.

I've noticed that if the doors aren't closed all the way, the headlights as well as interior lights will stay on. If you notice they are on (before the battery dies) go back and double check all of the doors and rear gate (or which ever ones people have gotten out of) and you will probably find one isn't completly shut.

Seems like a stupid way to let you know, since if you don't notice your battery will be toast when you get back.

[jameswharton]

On mine if I turn the lights off before I turn the engine off, they go out right away, but if I turn engine off then turn lights off, they take a minute or so to go out.
Jim

[HappyCurmudgeon]

On mine if I turn the lights off before I turn the engine off, they go out right away, but if I turn engine off then turn lights off, they take a minute or so to go out.
Jim

Same here. If you do shut the engine off first, you can kill the lights by cyling them on and off one more time.

My interior dome light stays on briefly after i exit (dims then shuts off almost immediately) but if i leave the door open for an extended time, the light stays on for a longer duration, doesnt make any practical sense to me, but that is what it does.

[Piginajeep]

On mine if I turn the lights off before I turn the engine off, they go out right away, but if I turn engine off then turn lights off, they take a minute or so to go out.
Jim

Right. its suppose to be that way....

[DadsCJ]

I was driving along and I heard a ding like a seat belt wasn't fastened. I looked at the dash and the ESP and BAS and the icon of the Jeep with slid marks were on. I pushed the ESP button thinking we accidently hit it and the icon went off. Pushed it again and the icon came on. The ESP and BAS lights stayed on.

Called my dealer, "We will need to see that as it isn't supposed to do that."

Really, now go figure....:D

The strange part is they all went off after about 30 minutes....

Everything seems to be fine now. :thumbsup:

[doojer]

ThinkMud! Got my flash today and I must say I'm impressed. I was never having any stalling or anything like that, but shifting was sort of erratic here and there. Especially on the highway, sometimes the RPMs would shoot way up and it would be searching for a minute before it would shift. After the flash, that was pretty much gone... way smoother. I wouldn't say I feel any more power, but definitely a better shifting pattern.

Thanks again for the heads up! :D

[sgt rock]

Wheeew.....thank gawd i am not the only one having an issue! After the new stereo install and alarm upgrade I thought they might have messed something up.... My esp light and engine light went on and somehow at times i felt like there was a drag (i have an automatic)....so today it went back to normal!
Just a tad afraid of driving home from Pendleton, Oregon (gawd I hate this state...becouse it is cooooold) to Phoenix, Arizona (sunny and warm) and wil have the dealership reset the computer.

AEV Bumper ordered and rear bumper from Jeeperman on the February run....

[stockYJ]

No real issues with the JK other than the poor shifting in the auto tranny.
I tried to get my local dealer to install the new Firmware, but they said the code was not available on the DC website.

Not only did the Easterners get the earlier delivery, but apparantly the internet is faster out there as well...ARGHH!!

I picked up my JK from the dealer in September and had it flashed yesterday. All I had to do was mention the TSB and the service guy printed it right out and said "Ya mean this one...? Yeah, we'll flash it for ya!" :yup:

You should try another dealer.

mine did that once

[HUMONGO]

The headlights all have to do with when you take your key out of the ignition. If you turn your lights out, then take the key out, the lights stay off. If you take your key out, then turn the lights out, they stay on for apx 30 sec.

Oooorrrrrrrr, the other way around. But I'm sure I said it right.

[stockYJ]

The dealer was in So Cal.
Just standard dealer jargon for we don't feel like performing that service for you today. I''ll try again another day/dealer.

[Rubimon]

Just wondering? I understand you have to get your comp flashed when installing a seperately ordered hard top because of the wirer harness that is added. Does this hold true for the missing footwell and under hood lamp too?They are adding mine and I wonder if it will need to be flashed?

[HUMONGO]

I just had mine flashed and it seems to have a little more power and has a much smoother sound, but it shudders real bad when the transmission shifts from 1st to 2nd and sometimes into 3rd. I was gonna go back to the dealer, but have to get an oil change next week-ish. I'd like to see if it goes away.

[jckid]

I had mine flashed yesterday. We had much better luck with the local dealer.

I'm not sure I noticed any significant power gains, like others mentioned, but maybe a little. It didn't seem to help the issue of it nearly red-lining sometimes when I stomp on the gas. I've found that if I stomp too hard on the gas, it will shift from 4th to 2nd and cause the rpm's to quickly zoom to 5,000. But I'm also figuring out that I can control it by paying attention to the way I drive. I'm starting to get a better feel for the Jeep now the more I drive it.

The one thing that the flash did seem to fix, was the clunk I could feel/hear when my transmission shifted down from 2nd to 1st when coming to a stop. The clunk seems to be gone.

I wasn't experiencing any of the electrical issues that have been mentioned, but I did have an occasional hesitation when starting the Jeep. Once in a great while (maybe 3-4X per month) when I'd go to start it, it would crank and crank and crank before starting up. I'll need a little more time to see if the flash cured that issue, because it was such an intermittent thing in the first place.

All in all, I'm glad I had it done. It seems to have helped a couple of issues, and it may have helped out in other areas I didn't even know about.

[Jeephrog]

Well I am driving to Colrado in a couple of hours and will take my Jeep to Lithia Chrysler in Ft. Collins tomorrow morning for the flash.

I called to make an appointment and gave them the TSB number and everything to make sure they had it downloaded. Hopefully they won't screw with me like I know the dealers here in NM probably would.

[ThinkMud]

Update status on my MPG...

still only 14'ish with half around town and half highway:(

oh well, i guess my 33"s and me removing the Air Dam, and my 3.21 gears can't be helped much...

good luck everyone else tho!

[ericdewayne]

i got 14 on my last tank and that was mostly highway! Just got the flash yesterday and it makes a huge difference with the sluggishness in low rpms. Its a real fluid acceleration now. I hope to god my gas mpg gets better. But then again, i do have 4.10's with the tiny little X tires. :(

and probably the lead foot of a fighter pilot!:rotflmao1:

[Rubimon]

To all of those getting their computers flashed, did you have problems, say you had problems, or fall before the manufacture date of the TSB? I need to get flashed for my new tires and would like to know how to approach it(without paying for it).

[ericdewayne]

i had the stalling problem one time about 2000 miles ago and never happened again and it was real sluggish in lower rpms till the flash. I also fell before the manufacture date. The people at the delership i went to are morons by the way. While waiting I asked a few guys in the sales room if i could look at the JK sitting out infront of the showroom. They all looked around at eachother with a bewildered look. Then i said... "uhh... the 07 wrangler??" "Oohhhhh why didnt you say so!?" nice....

[Kermit]

thanks to all, i was worndering, i put in a chip and the sloggishness went away but the battery thing didnt, i am taking it in.

Keith

[Jeephrog]

I got my flash done on the 23rd. I told them my radio was cutting out - which it did once - and told them that my battery light was coming on while driving - which it was not.

They first said that the TSB does not apply to my vehicle but they can fix the radio problem but they ended up doing the PCM flash and something for the radio.

So, on my drive to Colorado, about 400 miles about half of that on the interstrate, I got 21.5 mpg using 91 oct gas and averaging 75-80 on the interstate. Non interstate driving I averaged about 65-70. After driving around town for the past few days I am now indicationg around 19 MPG.

Also, I reset my fuel economy indicator at the beginning of the trip and will do so on the way back to see if the PCM flash made any difference in mpg.


I thought I noticed a slight bit more power right after getting the flash, but it is hard to say -- it doesn't really seem like different vehicle or anything.

[DadsCJ]

I had them do this TSB today for me and I do not see any improvement at all.

Shifts the same and the power curve is the same.

How do I check to see if they really did anything?

[ThinkMud]

hmm.. if you can't feel any difference, then either 1, your Jeep was built after the date specified in the TSB (i think it was like Nov. 10th) or 2, they didn't flash it with the updated software. and as far telling?? my service receipt thing had it on there, that the TSB was done, then gave a new version number. Hope that helps

[DadsCJ]

The receipt has the TSB listed as updated and my Jeep was made on Oct 2, 2007.

I wasn't having any issues like most everyone here, but thought it would be a good idea to upgrade.

I will keep an eye on it.

Doesn't the TSB say the dealer must put a new sticker on the Jeep after they do this to show that it had an upgrade? Where do they put the sticker?

[ThinkMud]

I don't think I got a sticker anywhere. Maybe yours didn't need it? just keep an eye out for any crazy electrical issues.

[britjk]

I had my oil changed this morning and also complained about my few electrical problems, like the radio cutting off at low RPM's, a few crazy dash lights going on then off. I complained so that they would flash my chip, b/c of the TSB about it, and it is soooooooooooooooooo worth it!!! my JK unlimited has 33" tires, 3.21 gears and is 6 sp...

Before the flash:
Ran ok, never felt like i had enough power, was very slugish off the line, very slugesh at any rmp under about 2.8k Would stall a lot. very slow and slugish response when i give it gas..

After the flash:
Runs like a completely different vehicle!!
no slugishness, very responsive, not really more power, just more constant power, it seems i can keep from down shifting a tad more now, like some turns in my neighborhood, where i'd used to have to drop down to 1st to hit, now i can take in 2nd easily, and i even made one in 3rd with out it studdering.

I am so glad I got this done! if anyone has a JK built b4 Nov. 10th, they should have it flashed, it is a huge difference in how it rides, shifts, ecelerates etc... i'm so stoked!
My 2007 black soft top 4wd 4 door Sahara with towing pkg. 18 in wheels - auto was made in Sept 06. Should I go to get mine flashed? The only problem I have had was my windows decided to stop working twice - until I pulled over and restarted the ignition - then everything is fine. What do I tell the dealer to get it flashed - the TSB #? Also how do I post pics on JK? I have tried twice.

[yellowjeeper85]

BritJK... absolutely go get it flashed. i had mine done today and i wasn't really experiencing problems as bad as everyone else. Only a light here or there and the radio woul kick out on occasion. but i had it done because my was build in sept 06 too and i figured hey its free, and everyone says it makes a great improvement. Let me just say that i'm so happy i did it. the power is so much better, not more power, but before it would like dip in and out of power. like full pedal and 5/8s pedal had power, between there it would kinda bog out. Now, its power the whole way up. and i have the 6 spd and noticed before the flash that i had a hard time determining when to shift when really reving it up. Driving like a grandma it didnt matter, but with my heavy foot it always seemed like no matter when i'd shift i wouldn't be in the right rpms once i got into the next gear.. but now its exactly how it should be, i shift when i feel it needs it and the next gear is waiting for me with plenty of power. If you go, i would recommend bringing a printed version of the TSB with you. i went to my dealer yesterday and the guy said "Well thats probably wrong because you can never trust what you read on the internet". I even had the TSB number and he didnt want to look it up, he felt it would be easier to diagnose the problem the long way rather than have me give him the answer... so i told him i'd come back in the morning. and this time i braught the printed TSB with me, and showed it to a different guy, this guy said "Awesome, pull it in i'll flash if for you, and while i'm at it, theres another thing to reprogram the radio to keep it from cutting out" here is the link for the TSB http://www.alldata.com/tsb/Chrysler/1163836800000_1164182400000_18-036-06/index.html go there, and print out the four pages and bring them with you. Good luck!

[Spozzie]

Have an automatic which I bought in Sept (so I guess it falls in the timeframe) not had the radio problem but it can be sluggish cruising at around the 40-45mph mark (sorry haven't noticed the rpm's) seems like it dont want to either change up or down and you have to give it a bit of gas to get it off/over the 40 mph mark.

Had a couple of instances where dash lights have come on unexpectedly anyone else with an automatic had similar problems and it has been rectified by the flash?

Yes. I have the automatic, i drove it home on the 11th of October.

It has some weird shift points, that is for sure; mine is flakey around 40-45 as well. The radio has cut out on me a couple of times, and the whole thing has just plain shut down on me 3 times now. Twice while driving, once sitting in a parking lot at idle. The dash lights all came on, then the engine & radio died, and the dash went dark. It started right back up all 3 times.

I have not, to my knowledge, experienced any sluggishness, the engine feels strong to me. This may change after i get it flashed though, i may not know what i am missing.

I am due in for service in the next few weeks, i plan on having the flash done at that time.

I also have the same question as posted earlier... ...how do i know for sure they actually flashed it?

[doojer]

...how do i know for sure they actually flashed it?The difference in the way the JK drives after the flash should be pretty noticeable. I noticed it the second I got on the highway... much smoother shifting and a lot less noise. If your JK was built before mid-November and you don't feel any change in performance (especially shifting pattern) after the flash, then I would guess that something was not done right.

[Piginajeep]

Yeah, just got back from my dealer.

He said there's no flash. His tech, said if he remembers correctly from a class he had. Just to pull a fuse to reset the computer....

I argued, the service guy said theres no flashes available for the JK. then he changed and said the only ones for a radio...

then i told him about reading it online, and he said its was for jeeps built before a certain date... i told him i took delivery mid october... and he was lost..
and went back to saying

"Hopefully by pulling the fuse it'll stop my power from cutting out".....


and further explained they dont have any tech certified to work on the new JK..:mad:




I'll be going to another dealer very soon..

This is my fear..I just know that the "supposed" 5 Star Dealership I bought my JK from and will be taking in it to get flashed, will act all dumb and not apply the flash. I am hoping by taking the printed out TSB and showing them in print that it may influence there decision.

Piginajeep did you take a copy of the TSB or just tell them about it? If not take it with you to the next dealership and let us know what happens.

[Spozzie]

this was suppose to be a 5 star dealer....:naw:


My brother is a service tech for a chevy dealer. He told me to run fast, and go somewhere else.. thats my plan.

[shredX]

Just had mine done. Very noticable. Smoother throught the RPM's, but the best is at the initial throttle tip in. Starts from a stop are much more natural.

[Jeephrog]

After I got the flash done, I drove around for a couple hundred miles in the city without resetting MPG indicator. Avg MPG went down to about 18.4 from 21.5 on the trip up to Denver. Then I drove 400 miles about 1/2 on Interstate and the rest on highways, over a mountain pass and through mountainy roads. Jeep was FULL with 5 people, christmas presents and luggage completely filling the cargo area, and a bike rack with two bikes hanging off the back.

Avg MPG went from 18.4 at the beginning to 20.5 at the end of the trip. There were times when road was flat for a ways where MPG went up to 21.7.

Anyway, it looks like the flash had some positive impact on gas mileage, considering the load and not resetting the MPG, but I didn't notice any change in power or shifting, though I wasn't having any troubles before.

[britjk]

I went this morning to get my 2nd free oil change - Ist for this year. My Dealer gave me 3 free oil changes a year. I got my TSB 18- 036-06 done. My 4door Sahara 4WD was made in 9/06. They did it for free - warranty he said. I don't know what happened - but - when I installed my clold air intake I noticed a difference. But after this puter reboot - I thought they had changed my engine to a Hemi. I have the auto with 4:10 gears - it drives like a hot rod now. I would recommend getting it done.

[britjk]

P.S. I watched them do it. But they didn't re-sticker my puter because they didn't have the labels yet. They downloaded the software from Chrysler.

[ThinkMud]

Glad it made so much difference! I installed some fog lights the other day and noticed a huge sticker right at the very front of my hood (close to the grill if closed). It said something like flash xxxx (number) then authorized by TSB number, etc...

[britjk]

I asked them - and they said they didn't have the stickers but next time I came in they would apply it. The flash is on record being as they did it under warranty.

[cmnah]

I had my first run in with the infomous Radio shut down. I hit a patch of ice in a parking lot this morning and slid. Radio went out. Came back on.

I'm scheduled to get mine flashed next week. Then I'll try the same thing again.

[hpjaz]

I, also, have had the dreaded battery light, dash light flutter and radio cut out. The dealer has mine in their shop now and I have given them a copy of the TSB, but they are afraid to flash the PCM since the TSB says it is for the automatic tranny... I have the 6 speed. (They don't want to fry the PCM with an incorrrect flash.)

Has anyone with a 6 speed had the TSB flash update? The initial post by Thinkmud indicates he has the 6 speed. Anyone else?
Thanks

That's crazy, the TSB didn't say anything about the type of transmission.

[hpjaz]

Item #4 under Symptom/Condition:
Improved automatic tramsmission shift quality.
Dealer says my vehicle will not take the flash.
Any thoughts?
Thanks

[ThinkMud]

They have to flash it, it doesn't matter if one of the symptoms is the auto. shifting. There has been lots of us with 6 speeds that have had ours flashed, I would call another dealer.

[mslc10]

I just bought mine in dec and havent had any of these issue (yet)....do you suppose they have done a flash?....and can you just ask for a reflash?

[Rubimon]

Everything built before 11-10-06 should get the flash. Check your build date. I think it is on the door panel.

[CommanderJB]

Should I have mine flashed before or after I install the AEM Brute force CAI?

[jeepfreek13]

I took mine in for the Flash....radio fixed; however, the VIN did not support the remainder of the TSB, however, my mechanic is stubborn like me and he called and waited on line with Star for 45 freeking minutes...the said they will have the patch ready next week.

[hpjaz]

The flash associated with this TSB was pulled from STAR by the DC engineering tech guys for "modification" and will be available again sometime in the next week (Week of Monday 1/15/07). Hopefully... as DC does move at their own rate.

As such, the flash is not available to the dealerhsips at this time and no dealership can do the flash until it is re-instated by DC. Looks like they are still working the bugs out.

That is funny... I was just thinking the other day that DC will probably have at least one more flash for our chips, b/c it still just doesn't seem 100% right on.. like the power(electric power) still seems to take a quick "dive" every so often at low RPM's and things dim, then come back on regular, this is when before the flash it would stall out, or act crazy. I hope they finally get it right on, that would be awesome, it's like getting really cool engine mods for free!!

We shouldn't get upset at this, they are obviously working on it, and that in itself is a good thing to me, at least they care enough to get our rigs running better, when they could just be like "who cares, you already bought it, deal with it" So good job DC, keep the updates coming!

[jpaddict]

I took mine in on Friday, and the dealer said my VIN did not support the flash.

Perhaps I should wait another week and see what happens.

[hpjaz]

ThinkMud, thanks for staying positive on this one. Many folks would just whine and try and tear DC a new one.

I have a little more info about the TSB that I didn't have time to add earlier today. According to the tech guys this is a PCM flash to cure an electrical issue. The alternators are overcharging. In some cases they are sending up to 16 volts to the chassis electronic elements: Battery, Radio, ABS, Air Bags, ESP – BAS, etc. Obviously this presents a voltage overload problem for these electronic items. Simply put, the PCM is directing the alternator to run full bore at times when it is not required. While the electronic elements can handle an overcharge to a certain degree they are designed to run on a 12 volt system. With the overcharge the systems start to shut down or re-boot. (Like the ratio cutting out and the battery light coming on.) Along with the flash are the power train changes that you have noted previously. Which is also reflective of a voltage issue. Actually, this TSB could explain many of the quirks people have posted about their JK's.

Hope this provides a bit more insight into this TSB. Got the info from one of the head tech guys here in Dallas. He has spent hours on it over the past week.

[ThinkMud]

Thanks for the info hpjaz. And I agree, there is no need to gripe about it, it's a problem, they are fixing it, we should all be happy right? I love my Jeep, and if I talked smack about it's maker, then I'd be talking smack about my Jeep, that's the way I look at it anyway. I have faith that DC will make things right.

[Rubimon]

You won't need it. Yours, like mine were built a couple of days after the deadline. You already have the flash.

How are you enjoying your rig?

[HighCountryJK]

Someone refrenced in a thread they had both TSB's done. What, is there two flashes that need to be done now. Call me stupid, but what does he mean, did i miss something. maybe i did.

[jpaddict]

Rubimon, I love this JK! I have the occasional radio cutout, nothing more.

Go look in "Write-Ups" and check out the Cibie Euro code lights I installed.

[yellowjeeper85]

i saw that too and wondered, i did have two TSBs done, but one was the flash and the other was a reprogram of the radio, which would do nothing for MPG

[HUMONGO]

Someone refrenced in a thread they had both TSB's done. What, is there two flashes that need to be done now. Call me stupid, but what does he mean, did i miss something. maybe i did.

There's a TSB to reprogram the radio completely.

[Rubimon]

Is your radio cut out just the satelite radio or does it happen on am/fm and cd's? I will check out your write-up.

Any update on the TSB being reinstated? I am going home to England and will be back the 30th and have my JK scheduled for an oil change (and hopefully get the chip flashed) on the 31st.

[HighCountryJK]

There's a TSB to reprogram the radio completely.

Thanks for clearing my confusion, it happens often.

Can you answer this, if i am lifting 4" and putting 35's on, would they have to reprogram something else to set the speedo agian, or will it be automatic with the TSB "Flash".

Also if you could tell me, if i have a jet II chip plugged in should i remove it first, before she get's "Flashed"??

You won't be able to get flash for the tires, they only do stock sizes, for now anyway. I sent DC a dissappointing service message because of this. Hopefully more people will to. You will have to go to one of those online calculators to determine your speed/mileage difference. 32's to 35's is about 10%.

As far as the chip goes I would remove it so you don't give them an excuse not to honor your computer warranty. Just my $.02.

[HighCountryJK]

I appriciate the feedback, i will take the chip off, so they cannot complain. Regarding the speedo recalibration, i will ask when i take it in. So there is no need to wait till i finish the lift, i will take it in soon, the electical "blincking out is annoying.

[HappyCurmudgeon]

Ok, the JK reached 3k miles & the stealership sent me a free coupon for my first lube & oil change. SOOooooo....

In addition to the free dino-pee replacement, it is supposed to be getting the TSB 18-036-06 & TSB 08-053-06 flashes done at the same time. :yup:
They called me and left a message that it is complete about an hour ago. (God help me i had to pilot the minivan this am)

I will get it right after work. Hopefully they actually DID the flash updates (i am skeptical to say the least).

If i notice any mentionable plusses or minuses i will certainly let everyone know!

[Piginajeep]

:mad:

my dealer still says there is not flashes available!

This is what I heard too. I printed them out and handed them both to the service manager last night when I dropped it off, as well as mentioning that I was fully aware of an impending recall.

He was polite and thanked me, but said it wasn't necessary as they would hook it up anyhow and do whatever ones where available. He looked like I may have stepped on his toes a bit, that wasn’t my intent. I just want everyone there to know I am not a 17yr old girl on daddy’s credit card away at school. I am by no means a mechanic, but I know my way around a toolbox enough to do a few things.

After reading all the responses on here about dealers denying the existence I am guessing on a runaround. Maybe not, who knows. This is my first service call at this dealership... ...we shall see :rollingeyes:

please let me know

[HappyCurmudgeon]

Ok, i received my Jeep back yesterday after work.

(For those interested, my Jeep was built 9/12/2006, and I purchased it on 10/11/2006.)

TSB 18-036-06 & TSB 08-053-06 are listed on the receipt as having been done. I checked this morning and there is a sticker under the hood stating the TSB 18-036-06 flash was done on 01/23/2007. I did not see one for the TSB 08-053-06 flash, but i looked @ 5am before my coffee, so i cant totally gaurantee it is not there, i will look again after work.

So, the flashes where apparently done. I do need to reset all my radio presets, so the battery cable was at least removed. *L*

I drove it briefly last night (about 20-25 miles or so) and it seemed a bit better around 2000rpm but i cant be sure yet, i need a bit more wheel time to get a good feel for it.

So far it hasnt miss-shifted like it did, and the lights havent gone on and off at random times then the thing keels over. So, so far, so good.

On a plus side, depending on your point of view...
It is clean.
They washed it!?!! Under the hood, inside vaccumed & outside scrubbed & shiney.
I am shocked. Lo & Behold, i purchased a silver Jeep. I had kinda forgotten.

It was a sorta muddy brown with a lightly salted coating. Now it is a shiney bright silver. Whooda thought?!?? :yup:

All in all, begrudgingly stated, i have to give the stealership's service department all 10's on their efforts. From experience at Ford garages, I expected to get screwed. I didnt.
This time.

[jameswharton]

Happy...do you know if you have revision G or ????. You will find it on the tag/sticker they put under the hoodin the part number of the flash. Many of us are waiting on the reported "J" version that is suppose to be available on or about the 27th.
Thanks,
Jim

That is a good question, and one i was curious about too but had forgotten to ask. I will run out on my next break and take a peak.


EDIT:

Ok, i looked at my sticker. it says:
Flash PCM
5187132AH

Then the flash # 18-036-06, then a dealer code which i cannot quite read & yesterdays date.

I dont know what the Revision is, i am uncertain how to read it.

http://i142.photobucket.com/albums/r82/HappyCurmudgeon/TSB18-036-06flashstickerfrom1-23-07.jpg

[jameswharton]

Well I'm guessing that you have a later flash than mine, my p/n is 05187158AG for the PCM and p/n 05107095AJ for the radio. Since yours has an "H" at the end, I would assume it to be more current. Maybe someone who knows for sure can chime in here. I wonder if the "J" revision that has been reported to be coming out was for the radio as that is what I currently have. I still think there is great improvement for the responsiveness of this fly by wire programming, especially at takeoff as mine still wants to stall. Hope the rumors of a more updated flash for around the 27th is true or Superchips or Hypertec comes out with a good programmer. I have the stage II Jet, but I think it is a waste of money compared to the other two I mentioned. Anyone else with any more current flash p/n's out there, we need to keep this going so we can each go into our respective dealers armed with knowledge. Too many people here getting blowed off because a dealer does not want the .4 hour warranty claim.
Rant over...for now:)
Jim

[JKJeepDad]

Hi guys. Just got the Jeep back from its first oil change and they did flash the PCM and the radio. I do not think they would have if I hadn't asked for it and showed them which TSB's I was talking about. They did sound pretty irritated that I was asking for it but they are both listed on my invoice as having been done. I'll have to check the stickers when I get home tonight and find out what exactly they say since I figured the service guys would be offended if I did it at the shop.
I don't want to overstate the performance after the flash but I can definitely tell the difference when going from 2nd to 3rd and 3rd to 4th. (6 speed) I don't think there is really more hp but the power is distributed more evenly in the gear range. All in all I think it is definitely worth bugging the service department until they do the flashes.

[jameswharton]

Well obviously the Star link is back available since a couple of guys have got theirs flashed yesterday and today. I wander if it is available to all dealers if it is available to one, or is it dribbled out some how?
Jim

[JKJeepDad]

I'm in Abilene TX which is not a thriving Metropolis and I would think if it is available here then it should be available pretty much anywhere.

[OJMiles]

Ok, i just checked, and my jeep was built after the date, but it still does everything that you guys describe in your "pre-flash" reports... Is the dealer going to give me any problems about reflashing it?

[jameswharton]

Depends on your dealer, there have been reports of folks with appropriate build dates that are getting refused because the dealer can't duplicate or they have the manual transmission, or some other crappy excuse. If it is doing these things...somethings not right and a dealer should fall all over themselves to help you. I have a great dealer in Wichita, KS who has been very good to me and I am thankful.

You taking it to Haynes? if so they should hook it up, they had no problem after I showed them the print out of the TSB...

[Spozzie]

Just back from a 10 day trip overseas and I have my JK scheduled for an oil change Tuesday morning and I hope the TSB 18-036-06, but prior to going away I saw that it had been withdrawn and was due to be reinstated Jan 27th. Can anyone conmfirm that DC has in fact reinstated the TSB?

[Wolfshead]

Thinkmud, I was going to ask which dealer in Richmond you were going to but you mentioned it above.

I have been going to Whitten (purchased dealer), have gotten less than stellar service recently so I wanted to get your overall impression of Haynes.

Thanks.

Haynes seemed ok, we've bought 2 jeeps from them so far, no killer deals or anything, the service guys seemed good, well the wrangler guys anyway, the "service advisors" didn't seem to want to do the flash at first, and tried to act like I didn't know what I was talking about, that's why I had to print out the TSB to take it to them. If you are happy with Whitten, then stick with them. I was even thinking of taking any of my next problems down there to see how they were compared to Haynes. Haynes did mess up my girlfriends rear main seal replacement, the first time, they kinked the seal and it leaked again, then she brought it back, then they put in some die to see where the leak was coming from, then did not see a leak and told her to pick it up again.. then when they drove from the garage to the dealership, they noticed it leaking again... so they had to fix it, they had it for almost a week to do a days job, so that wasn't cool at all.

[Wolfshead]

Checked the assembly date on mine today, 10/06. Will be sure to add this TSB to the list on next service.

[Spozzie]

Finally had the flash applied yesterday, as stated elsewhere the service managers were hesitant to do it and I had to give them a print of the TSB, I noticed on the work receipt they wrote "customer states gears not shifting smoothly, feels TSB is needed" errr dont get me wrong but on a JK built before Sept it is required. I didn't want to try my luck too much in one visit so I didn't request the roof leak TSB, but what gets me down is the attitude they give you and fight you have to put up to get your $23k purchase corrected.

On to the TSB itself, not had much of a chance to give it a run but from what I can tell it is much smoother thru the lower gears and they seem to be quicker changes.

[SJP-07JKx]

I called yesterday to make an appt for my 1st service at Whitten Jeep. I mentioned the radio cuts out on sharp turns or when both front windows are put down. Also the battery light stays on for a minute or so. She may have just been the coordinator but advised me to bring a copy of the TSB.

As far as dealers go I live near Haynes and buy all my accessories there but want to see how the Whitten Advantage plays out. (http://www.whittenbrothers.com/home.html) Free oil changes and tires for life every 25000 miles. Seems short for tire life but can't argue with free!

I'll report back on my TSB success.

[Wolfshead]

Made my appt for monday at Whitten. Will have copy of TSB in hand. Have not had the best of luck with the 'advantage' so far other than the whole oil change thing. I expect there will be a confrontation over the TSB....

[SJP-07JKx]

Picked up the JK last night and all seems good.

It might just be me but 1st gear doesn't feel like it drops off the world anymore when shifting.

I of course forgot the printout of the TSB but mentioned it at the Service Advisor Desk. He said they did it ....but I'll look for the TSB sticker tonight. The receipt just says "FPM" which he said means flashed processor module.

[HEK]

so I guess I posted on the wrong section but this is my experience and ...:yup: , don't worry about the "built date".....

My sticker was placed under the hood at the front but I have read various postings stating it had been placed elsewhere.

But here is the TSB instructions:

[Wolfshead]

I must give credit where it is due.

Dropped off the ride for 6000mi appt today, printed TSB's in hand (PCM, Radio Cutouts, Freedom top leaks) and requested that they be performed.

[Freedom Top has not been leaking but the main weather strip across rear section had a huge kink in it and the screws that secured the rear section to the B pillars were not installed..squeaky!!]

Whitten dealership did not blink. Performed both TSB's, ordered new weather strip and B pillar screws (back ordered :sad: ) without issue. Quite a surprise from past experiences with them. Kudos!!:thumbs:

As for PCM, quite a noticeable change. A little more pep in the step across all gears but especially apparent in 5th and 6th.

One more positive experience for this TSB.

Well I didn't find a TSB sticker. Thought someone had posted where it should be in the engine bay?

Mine is near the front of the hood by the latch, towards the drivers side. I was lucky enough to get the underhood mat, so that was about the only place they could put it.

I havent had any difficulties since the flash, i am still checking my milage, but to date i really dont think it has changed much. It hasent miss-shifted or cut off since the flash, but i am still not happy with the shift point right around 2k rpm's.

Anyone know of another site besides the Alldata site that has the TSB's listed? it seems that alldata is now charging for access to it's list, so we must find another place...:thinking:

HISTORY

I bought my JkU at the end of November, build date of Aug/06, 6 speed, 3.21. I had just left the lot and put up the front windows, radio cut out. Bought 1500 km's from home(so not local stealership)

Immediately took it back and they checked said there were codes for a fix, didn't refer to a TSB. Radio didn't cut out appeared to be working.

Brought it home every once in a while radio would cut out. Stalled once on my last week. Radio actually started to cut out about once a day. I phoned original dealer where I bought it and the service guy said it did not say specifically that a TSB was done just that there were error codes and they were addressed.

Made appt. with local stealership, went today with PCM TSB and radio TSB. They flashed computer.

IMPRESSIONS

Just picked up 1 hour ago, shifting seems a lot smoother now, go 200-300 more rpm's without that I need to shift feeling.

Little more seat of the pants power in 1st, 2nd and 3rd gear, nothing great but noticeable:D .

I know avg. mpg. is not very accurate all the time, but before TSB if I shifted more assertively but not aggressively (about where it feels normal to shift now) it would make the l/100km's drop almost instantly and after driving for a short distance it would go back down. Now it stays at what it was from the stopped position and then goes down. So appears gas mileage may have increased at least a little. (all city driving BTW)

QUESTION

When I originally bought it from the distant dealer and they did something to the computer is it possible they only did partial TSB and not all of it? Because my hometown dealer says it's not in the system as having been done before.

My mfg date says Nov. 06, and the cut-off for this is supposed to Nov. 10, 2006 I think. My service department told me that mine was not supposed to be effected but I was having the radio/dash lights issues, so they flashed it anyways. Had it done 2 weeks ago and it realy seems to have a better response when starting from a stop. Getting better mileage also. Seems to run soooooo much smoother. I'm pretty happy with the flash.
