Circuit Description

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.

Left Door Control Module (LDCM) provides output to heated mirror and door lock actuator. When LDCM receives LOCK or UNLOCK inputs from door lock/unlock switch or UNLOCK input from door key switch, LDCM will send appropriate signal to door lock actuator. When LDCM receives input from defogger switch, LDCM will send appropriate signal to activate heated mirror element.

DTC will set if LDCM detects a high current or short to voltage condition along door lock actuator control circuit when door lock is commanded by LDCM, if LDCM detects a high current or short to voltage in heated mirror control circuit when heated mirror is commanded on or if LDCM detects a voltage drop of 5 volts or more at BATTERY 2 circuit when door lock actuator is commanded. DTC will only be set as history even if condition is current. No driver warning message will be displayed. Heated mirror and door lock functions will be disabled.

For DTC to clear, rear defogger must be turned on. DTC will clear when conditions for setting DTC no longer exist. Driver's Information Center (DIC) or scan tool can be used to manually clear DTC.
