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 control module (RDCM) provides right motor control output functions. This output control allows RDCM to command right window up or down. Right window switch provides an input to RDCM when right window switch is depressed to UP or DOWN position. When RDCM detects an active window command from either right window switch or window command on serial data line from LDCM, RDCM will command right window motor in appropriate direction. RDCM applies ground or voltage to appropriate circuit (Dark Blue wire or Brown wire) depending on desired direction. RDCM monitors amount of current draw on right window motor circuit. If current draw is not within the acceptable range, a malfunction is present and DTC B2275 will set.

DTC B2275 will set if RDCM detects a short to voltage condition in right window motor control circuit when right window motor is not activated. This condition must exist for more than 20 seconds. DTC B2275 will store as a history code in RDCM memory. No driver warning will be displayed.

Under all fault conditions, DTC B2275 will clear automatically when RDCM no longer detects a short to voltage in right window motor control circuit for longer than 120 milliseconds. Current and history DTCs can be cleared using scan tool or on-board diagnostics.
