RABS Module wiring diagram
I need a little help here. The wiring coming from my rear speed sensor in the rear axle has some bad wiring. I discovered this chasing the rear abs light problems. after switching speedo cluster, sensor, and a whole lot of other nonsense trying to get my speedometer to work. Turned out to be the plastic clip holding the wiring to the brake lines. It had cut through the wiring from the rear speed sensor in multiple locations. I repaired a few breaks and weak spots along the line.
My main question is. Does anyone know if that wire goes all the way to the RABS module from the speed sensor? It looks like there are three wires coming out of the module. I just want to run a fresh line to the front of the truck where the module is located on the front drivers side frame to eliminate any other weak spots. The speedometer is bouncing all over the place and causing hard shifting again.
I couldn’t fin any posts about the speedometer not working because of a defective wire. Hope this helps a few other members fix their speedometer without replacing pretty much everything like I did.
