Power Door Locks

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 driver's door lock/unlock switch provides input to Left Door Control Module (LDCM) when switch is pressed to LOCK or UNLOCK positions. Input allows LDCM to detects LOCK or UNLOCK request. LDCM provides both power and ground to driver's door lock and unlock switches. When LDCM detects low voltage on driver's door lock input, LDCM will LOCK driver's door. LDCM will also send a message on the serial data line to Right Door Control Module (RDCM) to LOCK passenger's door.

When driver's door lock/unlock switch is pressed, the LDCM will UNLOCK driver's door and also send a message on the serial data line to RDCM to UNLOCK passenger's door. Lock and unlock output operation is similar for each DCM except that the polarity of the voltage applied to the door lock motors is reversed from each side.

The illuminated entry and delayed illumination features operate in conjunction with BCM and power door lock system. See ILLUMINATED ENTRY .
