It seems like many things can cause these lights to go on. Your symptom is little different than mine. My lights did not go on ALL THE TIME. Maybe 20% of the time. But ABS was kicking in constantly. For me it was a new hub and bearing as well as an alignment. Seems to be ok now. 3 weeks later and no lights. I was not getting the code you are getting either. Sounds like Mr. T has the right idea though.

I guess the shop was right about it not being the module. Ended up being a lose ground connection on the body. Somehow the bolt came loose causing the poor connection. The guys over at the shop cleaned it, added some medium strength thread locker, and tighten it back up. I’ve put several hundred miles on it and they haven’t came back.

I'm going to go look again, but in the meantime, is there anyone that knows where this bolt is?

Mr.T

Looks to me like under the hood, inside fenderwell. From memory there's more than one, check along both sides.

It's on the passenger side, same side as your battery. It's about mid-way along the side of the engine bay wall.

I'm also new to this Jeep world, always been a motocross guy with trucks. Love my new to me JK recently bought a ln 09 Wrangler X 3.8L 6spd. So far in the past three months I've had a few hiccups.
1.) Starter relay l - clicking and intermittently not starting. Simple fix with a voltameter and some cold beers!
2.) Those BS transfer case clips break so easily when offloading. Grab some zip ties and if you dont have em it's easily switched into 4Hi-4lo right under driver side transfer case!
3.) Got deep in a river, then caught by a rain storm in same day with no top. Next day horn would not stop blaring. Disconnected it and let it dry for a day or so. Reconnected it and good as new!
4.) Washed the inside (no carpet all herculined). Within am hour or so lights were stuck on and wipers went bizurk. No signals, dome, high beams... pulled some codes... UO126 AND C121A. Both pointed me towards the clockspring. Called the dealer recall out on that and the passenger airbag so getting it replaced on Friday. For a small bandaid I tried resetting the ECM by disconnecting the battery and connecting the terminals for 30 seconds. Rooted once they connected back, put the key on accessory and turned lights on and off. Then cut the key back to off. All the signals and everything worked until I started it back up. The bandaid I'm trying g is leaving it running for a bit with the heat on to try to dry it out. Food for thought for you guys!
Also have a set of 275/70r/18 Falken AT3 going on with 1.5 spidertrax tomorrow 😁

Hello all. New to the forum, but not to the jeep nightmares.

I currently have a 2008 JKU that I replaced all ABS sensors on. I am still getting the C1210 code. Purchased a used (tested OKAY) G Sensor from FLeaBay. Installed and still same code.

Did the "90 degree turn stuff" and code still there.

Just got it back from Jeep steelership $250 later and tech said he couldn;t connect to the G Sensor and that there was a wiring issue ... he wanted to know if I wanted to pay $139.99/hour for him to troubleshoot! F' no I said.

So now I have to look into the wiring of this thing.

Anyone else have a similar concern and can point me in a direction???

Thanks

P.S. I need the codes removed from dash so I can get it inspected. Just bought the damn thing....

Checked continuity with the 4 wires from G sensor to ABS connector. Found wiring diagram online.
Everything checks fine. I am at a frustrating loss. Going to check some grounds tomorrow.....

Opening this back up... my son's '07 had this problem and a local shop read the code for a bad ABS control module. We switched Jeeps for a few weeks while he saved enough money to get this done and while cheeking the oil I noticed that he had a slipped top radiator hose which was sending an antifreeze mist all over the engine bay.

Being THE DAD, I decided to degrease the mess and during the cleanup hit the inside of both front wheels with the cleaner. By the next day the Jeep dried out - no more codes. Tested the ABS with a couple of short stops and all good.

Another "Jeep thing" I guess.

Thanks @RepressedSince15 ! , My buddy, @EHarris had the same codes thrown on his '07 last week. He plugged in a code reader and he also received "ABS control module". I will make sure he sees your post and tries your fix instead of relying on the stealership to fix.
