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.
Right door lock/unlock switch provides lock input on Red/Black wire to Right Door Control Module (RDCM) when switch is pressed to LOCK position.
If the RDCM detects low voltage (short to ground) on switch lock input circuit for 20 seconds or more, DTC B2237 will set. DTC will only be set as history even if condition is current. No driver warning message will be displayed.
DTC will clear when condition no longer exists. Driver's Information Center (DIC) or scan tool can be used to manually clear DTC.
