Help. I was just driving to pick up some BBQ this evening. 2 miles down the road, driving straight at 40 MPH. All of the sudden, I get a warning bell. Look down and see the ESP/BAS light and the Traction light on. I looked in the manual, and it says if the lights stay on after a few engine start/stop cycles, I need to take it in to the dealer. There is a problem with the system. Lights came back on after getting the BBQ on the way back home. Any one else ever have this happen? Any pointers on things to check? Any way to reset?

Bump. Anyone?

Took it to AutoZone and they read codes. No codes. Checked all of the wheel speed sensor wires from each wheel all the way to main harness. All wires look good.

A scan from Auto zone or the like will not pull any code from the abs system. To my knowledge only the dealer can read those. Sorry I have nothing else to add.

I think you can reset by unhooking the battery for a few minutes. But if there is a problem it will come back on shortly.

Update... Problem solved. Strange reason for error lights. I had gotten an alignment at Firestone about a month ago. Over last weekend, my KJ started pulling to the right pretty bad. (I did not link this to the ESP/BAS error at the time) Anyway, Monday AM, I took my KJ back in to Firestone (a different location that happened to be closer to my work office) to have them re-align since it started pulling. The mechanic put it up on the rack, and found that the driver side toggle bolts for the LCA were both loose - like so loose that they must have never been tightened down when the alignment was initially done. So he aligned it and got all the specs almost dead center in the middle of the acceptable ranges. So I drive it on in to work from there. Then I go for my lunch break and the error lights are gone. And they have yet to come on again. So somehow, the extreme misalignment from the loose toggle bolts is what was causing the ESP/BAS error light to come on. I would not have thought of that one. But at least it is fixed.
