Circuit/System Verification

Observe the function of the door ajar indicator while opening and closing each door. The door ajar indicator should turn ON and OFF as each door is opened and closed

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate door jamb switch.
2. Ignition ON, verify the door ajar indicator is not illuminated.

• If the door ajar indicator is illuminated, test the control circuit terminal 1 for a short to ground. If the circuit tests normal, replace the IPC.

3. Connect a 10A fused jumper wire between the control circuit terminal 1 and ground, verify the door ajar indicator is illuminated.

• If the door ajar indicator is not illuminated, test the control circuit for an open/high resistance. If the circuit tests normal, replace the IPC.

4. If all circuits test normal, test or replace the door jamb switch.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
