AWD DISABLE LIGHT.

2004 Buick Rendezvous

Transmission problem
2004 Buick Rendezvous 6 cyl All Wheel Drive Automatic 58k miles

My dash is telling me " AWD DISABLE" . I checked on my gravel driveway it is front wheel drive only (only the front wheels are spinning).

What would cause this and how can I fix it? I recently put new brake pads and rotors on so maybe that has something to do with it. I have a scanner but this is not an error code or check engine light code.

Does the AWD system use the same sensors to detect spin as the ABS brake system? The ABS seems to be working OK.

Thanks,

It uses wheel speed sensors to determine wheel slippage. It could be disabled from a difference in tire pressures, or it could be a fault in the rear end pump assembly.
