Traction control / ESC light on

I just recently installed a Rock Krawler 2.5" Stock Mod lift and had the jeep aligned. Drives fine except for if I turn hard left or right the Traction Control light comes on and I can hear some grinding kinda noise. I think its trying to apply the brakes but am not sure really what the noise is. Alsthough I know the sound happens simultaneously when the light comes on. There is no rubbing or physical issue from what I can tell. Had my mechanic look at it, he spray painted some areas he though might be rubbing but everything is clear. (only running 33" duratracs)

Anyone else have this issue or have any ideas?

Is the steering wheel centered?

Did you damage an ABS harness or sensor during the install?

I dont believe I damaged anything during install, any indicators I should look out for? I dont even know what the ABS harness looks like

The steering wheel was centered at the alignment shop. It wasnt at first and the light was on 24x7 but after leaving it was off. Details of the alignment show it was definitely off.

Backspacing is 4.7" on the AEV Pintlers

On the front wheels the wiring harness is clipped to the brake hose. On the rear, the harness plugs in to the backing plate.

Backspacing is good then. I'm confused, is the steering properly centered? I thought you said it was but then maybe it wasn't? The latter would definitely contribute.

After the lift was installed the steering was off big time. The light was on 24x7. After taking it to the alignment shop the lights cleared. My assumption was that the steering was centered, how can I double check their work? Any ideas?

Pick up a Procal and center it yourself- couldn't be easier, I just cleared the same warning light myself last night. The steering doesn't have to be off by much to trip the sensor

If your Jeep senses a certain amount of roll during sharp turns the light will come on and it will apply brakes for you. after I put my anti-rock on I experience this more often. It is only during hard corners. You can take it to the dealer and they will flash the computer to widen the tolerance before the sensors freak out. I was quoted about 120 bucks. If it was steering off center the ESP light would remain on. Your lift might be allowing a bit more roll (softer suspension or due to height) than stock so the corners you used to take with no issues are now too much for the computer. I just take it a bit easier on corners now.

Also, if it was a speed sensor wire (abs wire) you would have an abs light, ESP light, and your abs and hill start assist (manual) would be inop.

I bet this is it, I can recreate it everytime with a semi-hard turn so it is probably the sensor not allowing for the added roll. Any idea if an AEV ProCal will fix this?

If not, guess Ill have to try the dealer, hopefully I sound knowledgeable enough so they dont try to take me to the cleaners.

No, procal can't really touch this. I'd just tell the dealer on sharp turns your traction control is freaking out and applying brakes. I never fixed mine because it has to be a pretty aggressive turn for mine to occur.

So I took it to the dealer and they stated that there was no such thing as adjusting the sensors. They did say that it was definitely the traction control. Their lead tech said best thing to do was just to turn it off which he did. Then they tried tk charge me $100 I was like no sorry not paying $100 for u to turn off my traction control. Anyway, the light stays in 24x7 now. Oh well, it's better than it kicking jn all the time right

Yea it wasn't to adjust the sensors, but to adjust the parameters in the computer. I got a quote from the dealer to get it done so either my dealer is clueless or yours is lol. Is it really that bad? Mine only happens on really right turns. Turning off esc completely doesn't seem like the right answer. Just a quick one. The lead tech sounds like he just wanted to get you out of there. Now you've lost a capability you paid for whether you wanted to or not.

Did you find an answer to this issue? I am going though the same problem. Please let me know.

My lights are on as well on my 07 JK, and it is completely stock. Thoughts?

Hrmmm...can anyone verify that Jager's techs are on top of it? If it really is a body roll issue that is something to factor into lift purchase decisions. I would be curious to know how many folks have this issue and with which kits if the amount of body roll is a factor in traction control activation.

Assuming body roll is the culprit, I wonder if the programming was updated...never had this issue myself on my 2012...could be that Chrysler decided a bit more electronic intervention was required and decided to make it so in order to keep folks from acting the fool and rolling the JKs.

As far as it goes, any parameter in the Jeep's ECU/programming can be adjusted either through a direct reflash or incorporating an in-line mod to the data stream between the sensor and control unit (much like fuel controllers modify fueling on motorcycles...they just piggy back the stock signal, modify it, send the modified signal to the stock ECU and presto). Finding a tech that wants to mess with it...that might be another matter entirely.

Lastly - re-centering your steering is easy, and any person/shop that installs a lift is certainly up to the job of spinning a turnbuckle about to accomplish it. No need for a Pro Cal unless you really feel the urge or want to use it's other functions.

I have a 3inch Fab Tec kit on mine. Any fuse I can pull to turn it off for now until I get it fixed?

We had a 2012 JK. We installed a 3" lift and 35s with new Bilsteins all around. After alignment it drove terribly... The traction control activated on every freeway off-ramp, even at two-thirds the recommended speed. Took it to two four-wheel dive shops we've worked with for years. $2,200 later the ride was improved and the suspension was stronger/better and more adjustable, but the yaw still activated the traction control. The traction control button doesn't really "turn it off". It just "reduces sensitivity". We followed the procedure to deactivate the traction control and that was as close as we got to a "fix". The idiot light was on full time. I called the service-writers for or two local Jeep dealers and the two biggest Jeep dealers in Oregon. They ALL told me there was no fix. Two actually said, "The Rubicon will drive fine stock --the fix is to return it to the way you bought it." After about six more months of fussing without success, we sold it. Last year we bought a 2005 TJ that doesn't have all the electronic bs to save us from ourselves, and we're back to loving Jeeping. I'd love to have a JK 4-door with the new Pentastar, but I'd never have the courage to modify one without seeing and driving a success story.
