I finally got a correct ABS module (three prong plug) and hooked it up. No dice. Still throwing these codes:

C1246 C1265 C1268.

C1246: ABS Outlet Valve Coil RR Circuit Failure

C1265: Lamp Warning Relay Short to Ground

C1268: Motor Relay #1 Circuit Failure

I give up. I’m not chasing this issue all over the place on a $1,500 truck. The brakes still work, so that’s a plus. I’ll just have to adjust snow driving to account for a lack of ABS.

I would get into the cluster and pull the bulb, but that’s too much trouble. Maybe it’ll go out on its own later like the air bag light occasionally does.
