Why is the AWD DISABLED light on.
Have tried thus far to Flush and refilled rear differential. Checked differential clutch valve and harness for corosion/breakage/foreign objects.

ONLY: AWD DISABLED light is on. No codes(dtc) advanced or otherwise showing. Scanned with abs code reader also and no codes.

All fuses okay.

As long as there are no abs codes stored,(even history codes, which will disable system) the most likely problem will probaly be that differential clutch pump actuator check valve.

I have the same exact problem. Is the rear differential module the same thing you are suggesting? It is basically a solenoid for for ~$400??
Thanks
