NOTE: Before troubleshooting, check the B-CAN DTCs. If any DTC is indicated, troubleshoot the indicated DTC first.

1. Place the ceiling light switch in the DOOR position.

2. Turn the ignition switch to ON (II).

3. Watch the ceiling light and the door indicators on the gauge control module.

Do the ceiling light and door indicators come on when each door is opened, and go off when each door is closed?
YES - Substitute a known-good MICU and recheck. If the symptom goes away, replace the original MICU.

NO - Repair an open in the wire between the MICU and each door switch, or a bad door switch.
