Traction control light flashing or staying on

Killer tip WestCoast! Haven’t had issues but gonna do it anyway

Everyone should do away with those cheap Factory clamps, bad grounds cause most of the problems. The neg clamp is the main ground for everything.

When your Jeep is in 4x4 it must turn the ESP off, put it back in 2wd and see if they go away.

It’s in 2wd but this pops up while driving

Any thing would be better than the cheap thing that they used from the factory.

Any way it could be tire sensors

No, TPMS has nothing to do with the ESP.

I changed clamps, I’m out of options any other suggestions on what to check

Have you scanned it for CEL's? Steering wheel not centered when driving straight and wheel speed sensor are the most common issues that cause those lights.

No I haven’t, can they do a scan for that or how does it need to be checked

Some auto parts stores will do that.

I’d suggest getting Jscan and BT OBDII adapter for future use. It is very helpful and can scan for codes. Total cost for Jscan license and adapter is around $50-$60 dollars.

I found the adapter how do I get the license

 

[Danarch]

I believe once the app is downloaded click on the gear symbol, then manage account licenses and account purchases a license.

I am having a similar issue, traction control, ESP and sometimes 4x4 lights flash and the chimes go off. Will go an hour without happening then it will go non stop for an hour then stop again for a while. I've checked all the grounds I can find under the hood, I ran another ground from the negative battery terminal to the alternator. Checked the wheel speed sensors, steering wheel is straight, battery is 14+ volts. No related codes. It's driving me crazy, 2008 JKU.

Similar issues on my 2008 JK. Thought it was related to low oil level (leak) but had that fixed. It quite for a awhile but now doing it again. Mine is the ESP, ABS and traction control.

ESP,ABS and TC is probably a wheel speed sensor. Take it somewhere and have them check it with a scan tool and they can tell you for sure.

Those were the exact symptoms of my loose negative battery terminal.
Error code was for a speed sensor and excessive battery voltage, iirc...
