The ESP/BAS & ESP/TCS Dash Lights just lit up on my way back to work. '08 JKU. Any ideas what might be the issue and what I can look at or check? :idontknow:

TIA

Usually speed sensor due to your lift. Mine comes and goes so l don't worry much about it.

I have an 09' and when my esp bas light was on it was my clock spring. Does your horn work? Does your CRuise control work? It can also be a wheel speed sensor or your steering wheel alignment.

For me it was always torn wires to the speed sensors. I also had the steering wheel off center causing it.

Do you have any electrical accessories hooked up to the negative battery terminal?

Check out your wheel bearing, too. A little play in the wheel bearing can cause a bad signal to the sensor and then it diasables all the electronic aids. Hill asist, bld, esp, abs....

Pull the DTC, majority of the time it's a bad wheel speed sensor. :beer:

Ive had this before as well after my lift, turned out my wheel alignment was out.
Fixed it, wheeled hard one a trail, came back on, redid alignment, and has since not returned.

Good luck!

Clock spring just verified good at dealer, cruise works and steering wheel alignment is good. Haven't tried horn but esp bas light went out on i's own for now. :clap2:

A standard code reader won't read those codes. It has to communicate with abs/srs. I would verify that you used one with those capabilities.

Is your steering wheel centered? Even if its off just a little bit it can piss off the ABS. It took several times adjusting and centering before it finally went away.

Thanks for all the suggestions! :clap2:

Everything seems back to normal, must have been a fluke. :idontknow:
