Diagnostic Aids
WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
If DTC does not reset after code is cleared, problem may be intermittent. While performing tests, move wires and connectors. Following conditions may also cause an intermittent malfunction:
- Intermittent open, short to voltage or short to ground in Black/White or Gray wire circuit between mirror and RDCM.
- Right mirror horizontal position sensor is open or shorted internally.
If RDCM is unable to determine correct horizontal position, manual power functions will still operate but RDCM will not be able to recall correct memory settings.
