I'm here trying to help my father with a Jeep problem. Hopefully you guys can help!

He bought a 2007 Jeep Wrangler X. He took it to a shop and had a 5.5" lift kit put on it with 315/70 R17 tires put on it. He is having problems with the ESP and the Electronic Roll Mitigation when rounding curves. WAY TOO SENSITIVE! He is not able to round a curve above 10mph. If he does those features kick in and he has a hard time controlling it.

Is there any way to disable these features? If so, how and where? If not, any suggestions on what we can do?

Thanks in advance!

P.S.-I believe in safety, but this is slightly ridiculous!

 

has he recentered his steering wheel yet, because if he hasnt then it will set off the esp and make it do weird things. mine did the same thing and then i recentered the steering wheel and the light went off after about 30 minutes of driving it.

 

What exactly is re centering the steering wheel?

Just to add a bit more information to the discussion if you haven't read some of the other posts regarding this problem - the reason centering the steering wheel is important is that the ESP software reads a sensor telling it how far you have turned the steering wheel. It uses this to determine the "path" it thinks you are steering. It also reads other sensors and accelerometers to determine the path it thinks the vehicle is actually traveling on. If these two paths are different by some predetermined amount, it kicks in the corrections (applies brakes on one side of the vehicle or the other and cuts the gas) to try and keep the Jeep traveling more or less on the path your steering wheel is pointing out.

So, if your steering wheel isn't sitting basically dead center when you are driving on a straight line, it thinks you are trying to turn slightly in one direction or the other. When you actually do turn, depending on the direction, the computer ends up thinking you want to turn either sharper or less sharp than the vehicle is actually turning and it kicks in the corrections. It sounds like this is what your dad is experiencing.

 

Thanks guys!!!! He was getting all upset over it and wanted to blow it up! lol He's going to do that and see what happens. I told him that if anybody could help it's more experienced Jeep people. Thanks again!

 

I also had this problem after I Lifted my X.
I took it back to the dealer and had them flash the chip to recgonize the larger tires.
The computer is set at the factory for the smaller tires the jeep came with.
All lifts also suggest a front end alignment after install of the lift, this is where you get your steering wheel straight.
after all of these things my Jeep ESP only comes on during big sweeping turns that Im going 40 mph or faster.
Hope this helps.

 

Im not saying an alignment is a bad idea, but centering the steering wheel yourself is extremely easy. It took me 5 tries with short, around the block test drives inbetween. Total time was 10 minutes to get it perfectly dead center. All you need is a 15mm wrench and a little patience to get it perfect. My esp actually kicks on less now on pavement then it did before the lift and spacers. In fact it has yet to turn on on pavement and I have tried a few times to see if it would.

 

Can you go into more detail where the bolt is to center your steering? Maybe even some pic's?
My steering wheel is a lil off and didnt want to pay for another alignment.
Thanks in advance.

Its two 15mm nuts you loosen on the steering linkage turn buckle. Eddie has a good pic of it in his write up.
