ESP/BAS/ABS Lights On and Off Randomly
I've read several other threads about this type of issue, but I feel like mine might be slightly different.
The three lights come on randomly with a chime noise about once a week. It happens when I'm driving on pavement going straight, and the brakes aren't applied or anything like that. They only stay on for a few minutes, and then they turn off.
I installed a 2" budget boost a few months ago, and I'm wondering if that is what is causing the problem. My steering wheel seemed aligned after the lift, so I didn't bother doing an alignment. Should I do an alignment anyway? The steering wheel seems pretty straight...
I read that I might have a bad sensor on one or more of the wheels. Is there any way to check and see if the sensors are causing the problems? Or will I have to take it to a dealer and have them check it out? I'd rather do it myself and save some money.
Any suggestions?

first and foremost, you need to make sure that your steering wheel IS centered. if it's off a bit, your computer will think you are in a slide and it will cause your esp to kick off. IF you are sure it is centered, you need to make sure that you aren't running to much air in your tires. if you are running 33's - you want to be running at about 30-32 psi. with 35's about there or a bit less. IF you are running the correct psi, it's possible you have a speed sensor going bad but, i would bet that is not the case.
I checked my steering wheel alignment and adjusted it slightly. It was VERY slightly off, but I corrected it just to make sure that wasn't an issue anymore.
I also checked my tire pressure. The front tires were down to 29 psi, which I didn't expect. I'll try inflating them to about 32 psi and see what happens.
It may take a few days to see if my adjustments worked, but I'll let you know if the lights turn on again.

I am experiencing a similar problem like yours. Have you check the DTCs? This is what mine came up with....I have another thread on this subject...Hopefully more members will chime in with a few suggestions before I (we) take it into the dealership....
Hello All,
I have had my lift over ~5mos now and never had this issue come up until these last two days. Has anyone else experience this problem? If so what was fixed. Is this a module & wheel sensor issue? Just want to get some input so I can be better informed when I try to take it to the dealer for repair..Please advise, thank you.

I've done very little wheeling recently, but I'll check to see if the sensors are attached anyway. I don't know if there are any diagnostic codes, because I have no way of seeing them.

I've been having problems with my Jeep since I bought it a year and a month ago.
The electrical system is either a piece of sh*t on this thing..... I posted a thread a while ago explaining the problem and have brought my Jeep in about 5 times for this specific problem.
The first thing that happens is that the ESP/BAS lights and the Traction Assist icon come on accompanied with a chime (like the one when you need gas or when your seatbelt is off).
After that happens, every other light starts to come on and off sporadically and the tachometer jumps like a mexican jumping bean. The lights include: Red circular light above the water temp, the airbag light, a red lightning bolt icon light, a red oil can/genie bottle light, and some others that I can't remember.
The odometer area is also affected during this flurry of a seizure. It will put boxes around all of the letters as if I was in every gear (PRND) at the same time. The "HOT OIL" message flashes.
Also, on two separate occasions, the seizure resulted in the car applying the brakes for me as if it was protecting me from a skid-out. The only problem here is that I was going straight down the road @ 30 mph with my foot on the gas pedal when it happened.
-----------------------------------
The service performed included (in chronological order):
-Replacing the ignition cylinder
-Replacing the ABS computer
-Removing my aftermarket radio (they initially thought this was the problem, but apparently not) and replacing the factory radio.
-Replacing the "Module A"
(after the last 2 "repairs" the heat stopped working - blower was fine, but no heat came out)
-Replacing the clockspring in the steering column
-Replacing a switch that made my blinker stay on (this didn't happen ever when I drove the car, so I'm guessing they broke it during maintenance - they just listed this on a separate invoice stapled with the repair on the clockspring)
---------------------------------
Does anyone else have this problem? The car is stock and this is really a terrible car that I would never recommend to anyone ever. It's unbelievable that they can't fix this problem, but even more disturbing that the Jeep's electronics are equivalent to that of an Atari (at best).
I had posted a reply to another thread somewhere on jk-forum.... if I can find it, I'll edit this post and put a link to it - but it has pretty much all of the same info.
Bottom line: I loved my 98 Jeep Cherokee Sport - it ran like a beast. The trasmission was solid, the I6 had less horsepower but was more punchy and responsive, and the electronics didn't spaz out. This new 2009 JK Wrangler I just got last August looks great, but is one of the worst cars I have ever used in my life. I would never recommend the car to anyone as it needs to be taken in for service at least once a month on average.
IF ANYONE HAS HAD THIS PROBLEM AND FOUND A SOLUTION, PLEASE POST A REPLY!!!!!!!!! I'M TIRED OF CLEANING MY VOMIT OFF THE FLOOR EVERY WEEK FROM USING THIS CAR.

The easiest way would be to use a programmer such as SuperChips or Hypertech, but if you have none, Here is a link that gives you step by step instructions for retrieving the DTCs
