Diesel issue with ABS Traction Control and 4WD service

[LakeshoreJeep]

The shop manager just identified and repaired the issue. I will express it to you for your knowledge. Drivers side wheel sensor wire harness running along the driver's side engine compartment had an intermittent interference with the steering column joint. When the truck was in a turn or wheel was articulated in the correct manner it was rubbing the steering column. Over the last 6 months it worn the insulation down till it started shorting the wheel sensor causing the ABS to have a hissy fit. Seems resolved at this time. The clearances of modern vehicles are so tight a wire harness a little loose can cause a world of issues. And it made sense at first it happened once then 10 days later again. Then progressively more and more often. To the point a 5-minute drive would trip it 3 or 4 times. Shop manager traced the wires found the abrasion and reinsulated it and moved the wire harness so it could not interfere again.

I'm sure glad you posted this. The description of your failure matched mine to a T.
I wasn't sure what I was going to do with an intermittent problem like this. I was sure it would end up like yours, with a lengthy stay at the dealership.
After I read your post. I inspected my harness at the steering shaft, and I could see where the harness had been rubbing. The dirt was polished off of the steering knuckle.
I popped off the retainer that was holding it too close, taped up the harness, and zip tied the harness to a more suitable place. Problem solved.
Thanks again for the post & updates.

I had this same issue for months. Blamed wheel speed sensors, abs sensors, abs modules. Finally a tech found an abs sensor plug that wasn’t fully seated. Haven’t had the issue pop up again.

Mine started doing this in Moab this Spring. Seems to do it mostly on curvy roads. Faults for left wheel speed sensor, but it was not the sensor. My steering column is rubbing the harness.

I just pulled it away from the column, I’ll check the wires when I have some time. Thanks for sharing the info.

Did anyone find a good solution to this problem. I have the same thing as the dash pictures above, ABS, traction control, and Serv 4WD drive lights are all on. Can get the Jeep in 4WD but unable to get cruise control to work. It is no longer intermittent but are now on permanently. So many ideas on this thread as to what the problem might be I am wondering if anyone found the cause. The dealership said they wont have a master technician in until the end of July. Now I am wondering if it is safe to drive it that long with these issues.

Please let me know if someone has found a definite answer to this.
