ABS/ESP lights on dash
Hi everyone, I've had an issue over the last little while with the above lights being on in my dash.
Originally, I had intentionally left a replaced speed sensor unplugged because I felt the Jeep drove better in the summer without it. Now I want the ABS to be on in the winter months, so I reconnected the sensor (front passenger side) but, the lights on the dash did not extinguish.
The code that was present was for the driver side rear.
Took it to a mechanic (Jeep specialist) and he scoped it out and said he wasn't getting a signal.
Replaced it but the same thing it there.......ugh
!
Anyone have a suggestion? Anyone have a wiring diagram?
Could a fuse be the problem?

I guess I'm at a point where either I spend time tracing the wires or pay someone to do that (prefer the former) but like I said, a wiring diagram would be helpful. I'm sure it's not an intricate system. Sensor on the wheel bearing, wiring to a plug near the rear axle, wiring to the ECM in the engine bay?
It would be nice to get the system running before I'm dealing with ice and snow

Well I finally found the problem after much testing and digging . Thru using a factory service manual for the wiring schematics and testing circuits at the 2 main terminal plugs for the ABS module to WSS I found the supply power wire was open , green wire with blue trace . The wire was oped at a factory splice about 24" back from the WSS plug . I repaired the break and now all is good , no fault lights , no codes and my cruise works again along with ABS and ESP etc . Sometimes perseverance and being a retired auto tech pays off . Cheers
