Circuit/System Testing

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The rear drive clutch solenoid valve is calibrated with and is part of the rear differential clutch control module. Both components must be replaced as a matched set.

Verify DTC C039F is not set.

If the DTC is set, inspect the rear differential assembly for internal or external mechanical damage and repair as necessary. Clear codes and road test. Verify that DTC C039F is not set. If the DTC resets, replace the K47 rear differential clutch control module/Q48 rear drive clutch solenoid valve assembly.
