WARNING: This page is about a different car, the 2000 Chevrolet Corvette and 1999 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
The following conditions may cause an intermittent fault:
- Intermittent short to ground in lock input circuit.
- Door lock/unlock switch is sticking or internally shorted.
- Door lock switch was pressed to LOCK position for more than 20 seconds.
If lock input circuit is shorted to ground or switch is stuck, RDCM and LDCM will continuously lock doors. Monitor DOOR LOCK SWITCH status on scan tool and disconnect door lock/unlock switch. If status changed from ACTIVE to INACTIVE, replace door lock/unlock switch. If status does not change, check for short to ground in Red/Black wire.
