Rear Axle Wiring Diagram

Looking for some help in diagnosing a problem with my rear axle wiring. I ran over a stick doing some yard work approx a year ago and tore up my ABS line from the connector at the body. I replaced this ABS harness and it has been working for the past year without any issues, then my ABS light popped on.

I jumped my pins at the OBD and got code 33 which is for my Right rear ABS sensor. I inspected the harness and there were no obvious deformities noted, so I pinned the harness at the WSS which revealed a voltage drop to 5.7ish volts. I replaced the harness again and I attempted to clear codes but I continued to get the same 33 ABS code. I measured voltage on the new harness and it was the same 5.7ish Volts at the WSS. I worked my way back up the harness to the body connector and pinned the actual sites and got 5.7ish to the Right rear and 11.7 to the left rear. I have not taken the harness apart yet to inspect for damages but I was looking to see if anyone has experienced a similar issue or if anyone has been able to locate a wiring diagram for the rear axle. I drive a 2012 Off-road Access cab if anyone does happen to have a diagram. Looking for suggestions for attempts to repair or how to proceed as well. I’ve tried looking for PN for the rear harness and can’t seem to find anything unfortunately as well.

appreciate any insight!

edited: stated wrong ABS code earlier

 

I'll grab some schematics for you hang tight. In the meantime...swap the sensor with another one and go for a drive, see if the code follows. Might just be a bad sensor.

Edit: just reread and realized you're getting a voltage drop. Disregard above

 

I got diagrams, but the the pin number are different at the Skid Control ECU depending on Vacuum or Hydraulic type boost.
They are the same from the sensor to IB1.

I've included that below. Let me know what type booter you have.
I can add more then

Left Senor on left - Right on Right.

 

was just about to ask if he had vacuum or hydraulic.

 

BTW, My data shows that code #36 is for the Left FRONT sensor.....

 

And the info for that code says 7.5v - 12v is good.
I think maybe you are chasing the wrong sensor?

 

I stated the wrong code, I’m getting code 33, not 36. I had a 56 for an accumulator issue that’s been resolved and mixed it up.

I have the hydraulic booster, it’s an off-road trim model.

Appreciate the help.
