ESP/BAS, TCS and ABS lights on

[Hilltop]

this may have been covered before but i couldnt find a thread coving it.

All 3 lights are on, they go off if road conditions are good for a while but soon as I spin a wheel they come back on. Cruise control does't work once they come on either. My questions is kinda about trouble shooting, is there 1 module or the same sensors that contols all both systems, basicly where should i start looking for the problem, before i tell a machanic to just start fixing stuff id like to have a little info, so i dont end up with a lot of new parts i dont need or exploratory labor they charge me for, lol

Any info would be great.

Check the speed sensor that lives above your rear differential... and also the wires leading down to the sensor. Although not common, it's possible for the wires to rub the emergency brake cable and wear through/short out. I had it happen twice with mine before I zip tied the wire up and out of the way.

Oh, and (welcome)

Also check the ABS sensor wires that plug into the front hubs. If the wires pop out of the little clips that hold them, they can rub. Had the same issue you are describing and that's what it was.

Thanks guys, I will check those couple things out as soon as I can. Hope I can get it working, roads have been pretty bad lately with more to come I'm sure lol.

Do jeeps have a limp mode? When i had my turbo passat if i had to much wheel spin or the computers sensed a problem limp mode would kick in and cut the power dramatically and show warning lights.

Not that I've noticed. Mine has factory ABS, and did not seem to go into any kind of limp mode after it activated during the first winter I had it. I've since pulled the ABS pump fuse so it doesn't engage.
