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 :redface:

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.

 

What is the backspacing on those 17s?

 

Backspacing is 4.7" on the AEV Pintlers

 

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.

 

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. :hide:

 

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.

 

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.

 

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.

 

Another situation where a Speedo recalibrate would have solved that issue.

Im having same problem. anyone have a fix? i installed a trail dash that solved a few of the computer problems, but the traction control light will still come on with sharp turns (on/off freeway ramps mostly). any help much appreciated

 

The AEV Procal is designed to help with these issues. You have very sensitive sensors on your jeep that will activate ESP without the correct calibrations. To give you an example - I have a 2015 JKU w/ 33x12.5's and a Teraflex 1.5" leveling kit. I'm extremely OCD and installed everything myself w/ proper tools, steps, torque, road force balance, drag link correction, ect ect. I had the same problem.... Go around a sharp corner above 45mph or especially around a sloped corner (on or off ramp) and ESP would kick in. I thought something was seriously wrong until I started doing lots of research online and in this forum . A friend of mine had a new AEV Procal so I bought it that day / recalibrated everything with it and ran some laps around town. Absolutely no problems and drives like a dream. I even reset my TPS so that I can run my Duratracs with perfect pressure. Couldn't be happier as it does a lot for $170!!!

Unless you plan on turning off ESP with the steering wheel dance (Which could be useful when off-roading, doing donuts, feeling free, ect) this is the best option in my opinion. It truly helps you "correct" the changes you made that may have seemed small

Did you change your gear ratio using the AEV Procal or just the tire size, HB420?

 

hi rockred...thanks for the reply. I used my AEV Procal to adjust the tire size to 31.5" and still having a grating sound like metal rubbing along with the wavy line dashboard 'Traction Control ESP' light occasionally (happened twice yesterday going down a long, curvy mountain paved road called Highway 74 near Palm Desert CA). It really only has happened going downhill and not uphill. And the turns it happened on aren't super curvy. Any ideas?

It's a stock Jeep Wrangler JK 2008 (second year they made the four door and has a lifetime powertrain warranty hoolah!). Had a professional install a 2.5" rough country lift with new shocks and new front drive shaft. AMERICAN OUTLAW RAILCAR17 X8.5 5-127.00 10 BKGLMN wheels and NITTO RECON GRAPPLER A/T33 X12.50R17 LT 124R F2 BSW tires. Can't figure out what is going on and how to prevent it from happening again! Any feedback would be super appreciated from anyone as it feels dangerous and would hate for it to happen in wet/icy conditions. Cheers.

 

I don't see any wear to the naked eye and here is my troublemaker:

also need a paint job on the hood and decent front/rear bumpers. Did install a couple LED headlights and a turn signal lever myself, so ain't a total tard.

Again, any feedback on the ESP/Grating sound disaster would be awesome. Thanks y'all.

 

You are quite correct re the ESC/TC control device activating when not appropriate can be very dangerous.
My 2013 JKR activated the ESC/TC device on a downdhill, curvy section of Interstate 5 when the Jeep was brand new, bone stock, right off the showroom floor on its maiden voyage to Southern Cali from Washington State. ! I thank God, I was on a 4 lane highway because I was all over the road. The other drivers near me must have thought I was drunk.
Shortly thereafter I had a teraflex lift installed and never experienced the ESC/TC device inappropriately activating EXCEPT when traveling off pavement. I found the only cure to alleviate the inappropriate ESC/TC activation when traveling off pavement was to install a kill switch to the power feed to the ESC/TC control module under the center console. [this kill switch also inactivates the ABS and cruise control functions].
In your particular case I can only assume you have a intermittent faulty wheel sensor or perhaps a faulty ground connection somewhere.
Sorry to hear you had the Rough Country lift installed! Whoever installed that lift did you no favors!
Sounds as if you are a local Jeeper! I am very familiar with the Palms to Pines highway!

 

Thanks Sir. The ESP/Grating sound only happens for a few seconds and the jeep isn't super swervy like you experienced but it's still the helpless, lack of control feeling and immediate desire to brake when shouldn't have to brake. Super frustrating. And I bought and chose the RC Lift so it was my ignorance on that. I'll possibly ask my lift installer to review the wheel sensor/ground connections.

Nice on P2P! So many great rides out here in the Coachella Valley. I've been more of a dual sport motocycle guy (just sold my 1999 Yamaha WR400). Tons of spots out here to jeep as well (top of santa rosa mountain, back road pioneertown to big bear, johnson and apple valleys, borrego springs, etc etc etc.).

 

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?

Did you put bigger tires on and not reprogram your speedo? If so your wheel speed sensors are reading the wrong values. It’s reading The differential between wheel speeds from left and right so it’s reading that difference as skidding hence the reason it happens when cornering and wants to activate the brakes to one or the other rear wheel. If the steering wheel wasn’t calibrated it would only do it when turning in one direction only.

hi Jeff...any feedback or advice on my above issue?

 

You are in my Wheelhouse with the 08 .. I bought my 08 new, drove it for 10 years 321,000klm , loved that Jeep.
That grating is the traction control kicking in, hence the light as well.

• Have you compared your speedometer to GPS app to confirm the tire size is set right?
• Have you had your steering wheel calibrated to center?

If those 2 things are done and still an issue you can pull both back wheels and check that the wheel speed sensors and tone rings are clean. Pull the front wheels and check the unit (Hub) bearings. The sensor and tone ring are inside those unit bearings . You can pull the sensor out to check it. The pre 2012 JK is a much simpler set up. If the traction control is really acting up you can simply UNplug any one of the wheel speed sensor and it will just disable traction control without affecting anything else. Many guys around here actually run a toggle switch to one of the front wheel speed sensors so they can easily disable or enable traction control at will.

Make sure your trackbar is torqued to specs. Get down there with a torque wrench and make sure both sides of the TB are torqued to 120ft/lbs.

 

Appreciate it, Guys!
