Yes! this makes perfect sense. I have the same 'problem' as once you lift the truck and especially when you change the tires/dimension of the wheel in relation to the stock conditions for the traction control module, it will complain at full wheel lock (e.g. u-turn).

I noticed it only happens when I do a U-turn quickly, if I take it slowly it does not happen. So I now take my time in a U-turn

I think the SL guys have to use an ESP recaliberation system to change to the traction control module as the severity gets higher with the more extreme lifts (don't quote me on this but this is my memory from the hundreds of threads read over the years ).

hope this helps

Same issue here. I've dealt with it for YEARS. U turns at sloooow speed if I'm careful won't do anything. But hit a curb on a turn and it's ESP city!!

I have calibrated my tires with superchips but it didn't do anything but change the speedo. I've also seen the module for the bigger lift kits that dumbs down the ESP system, more or less. But I only have the RC 2".

Turning off the ESP by pressing and holding the TC button rids the issue, but then I'm driving with no ESP, which defeats the purpose.

HEEEELLLLLPPPPP!!!!

Thanks to my goldfish like attention span, I completely forgot that this thread was moved from the "Off Road Modifications" section...in regards to the ESP, and strictly my opinion from my experience with driving a lifted WK before the EGR was installed, driving with an un-calibrated ESP was more dangerous than driving without it. At the time I did not know that holding down the TC button would completely turn it off since the '07 owners manual did not mention it. After the EGR failed, I installed a Bully Dog GT gas tuner which will calibrate the speedometer, but does not reprogram the ESP. Personally I prefer the Bully Dog over the EGR since it also gives a bump in horsepower and torque as well 2-3 MPG better than I was getting. However if you just gotta have ESP on a lifted WK, go with the EGR.

BTW, I hit the trails recently.

Re: The Official Lifted WK Thread

I don't follow you here. What does the EGR have to do with the ESP system?

Re: The Official Lifted WK Thread

I believe the EGR that No One is referring to is the Electronic Geometry Recalibration Module (which corrects the inputs for the ESP system), not the Exhaust Gas Recirculation system.
However, an article at Jeep Grand Cherokee WK - Electronic Stability Program (ESP) explains that
1- the ESP on the Grand Cherokee cannot be set to fully off, only partially off;
2- the low-speed traction control is always on, even when the ESP is partially or fully off.

So No One, does your ESP act up when turning at full lock?

I'm also interested in this because I'll be lifting my GC when I get the Bilstein 5100's that I ordered in January. I've had five 265/70R17 Fierce Attitude tires mounted on Pro Comp wheels sitting in my garage since April.

Re: The Official Lifted WK Thread

I've seen the module for the superlift kits, but I only have the 2" kit and am not sure if that's something I can use or not.

QUOTE]

When the ESP engages, the "ESP BAS" light at the bottom of the instrument cluster begins to flash accompanied by the grinding noise from the brakes. This has not happened in an U-turn, full lock, or normal cornering with the ESP manually disengaged. Whatever that threshold is, I have yet pushed it to that point.

Re: The Official Lifted WK Thread

My bas light turns on when esp engages when it is supposed to. I.e snow and ice when the jeep gets squirrely. But Don a u turn or when jamming a curb when the brakes grind quickly (false positive) it doesnt.

Have the adjustable ball joints helped with that issue?

Re: The Official Lifted WK Thread

I'm at roughly 6" of lift with 4.10 gears and 305's with no ESP issues... The AEV EGR module works perfectly 99% of the time. Every once and a while if I restart the jeep within 20 minutes of shutting down (aka stopping to get gas on a long trip) I'll get the ESP and TC to fail and they will not reset until after I shut down for 20 minutes or so. The ESP NEVER fails during normal driving. Unfortunately the AEV EGR only works for those with the Superlift as it recalibrates for the suspension changes associated with taller spindles and subsequent changes to the steering geometry.

Re: The Official Lifted WK Thread

Yeah I'm curious what it will do for a 2" lift/level kit.

Might be trading in for a '15 outback anyway soon...
