Door Ajar Indicator Malfunction Non Panel Van

The body control module (BCM) provides voltage to each door jamb switch via the door ajar switch signal circuit. The door lamb switches are permanently grounded. The door ajar switches are normally open when the door is fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground. The driver information center (DIC), illuminates the DOOR AJAR indicator when the BCM detects that one of the doors is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the door ajar status. If this message is displayed and the vehicle speed is greater than 5 km/h (3 mph), a chime will sound.

Control Module References for scan tool information

1. Ignition ON, observe the scan tool Driver Door Ajar Sw parameter while opening and closing the driver door. The parameter should change between Door Closed and Door Ajar.

⇒	If the parameter does not change, refer to Driver Door Ajar Malfunction.

2. With the passenger doors closed, observe the scan tool Door Ajar Switch parameter while opening and closing each door. The parameter should change between Door Closed and Door Ajar.

⇒	If the parameter does not change, refer to Passenger Door Ajar Malfunction.

Driver Door Ajar Malfunction

1. Ignition OFF, disconnect the harness connector at the LF door jamb switch.
2. Test for less than 1 ohm between the ground circuit terminal B and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool Driver Door Ajar Sw parameter and is Door Closed.

⇒	If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM.

4. Install a 3A fused jumper wire between the signal circuit terminal A and the ground circuit terminal B. Verify the scan tool Driver Door Ajar Sw parameter is Door Ajar.

⇒	If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

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

Passenger Door Ajar Malfunction

1. Ignition OFF, disconnect the harness connector at the appropriate door jamb switch.
2. Test for less than 1 ohm between the ground circuit terminal B and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool Door Ajar Switch parameter is Door Closed.

⇒	If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM.

4. Install a 3A fused jumper wire between the signal circuit terminal A and the ground circuit terminal B. Verify the scan tool Door Ajar Switch parameter is Door Ajar.

⇒	If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

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

1. Ignition OFF, disconnect the harness connector at the appropriate door jamb switch.
2. Test for infinite resistance between the signal terminal A and the ground terminal B with the door jamb switch in the open position

⇒	If not the specified value, replace the door jamb switch.

3. Test for less than 2 ohms between the signal terminal A and the ground terminal B with the door jamb switch in the closed position.

⇒	If greater than the specified range, replace the door jamb switch.

The body control module (BCM) provides voltage to each door latch via the door ajar switch signal circuit. The door latches are permanently grounded. The door ajar switches are normally open when the door is fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground. The driver information center (DIC), illuminates the DOOR AJAR indicator when the BCM detects that one of the doors is open.
