Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

Verify that the door ajar indicator malfunction is present.

Does the door ajar indicator operate normally?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

Is the door ajar indicator ON all the time?

Go to Step 4

Go to Step 6

1. Install a scan tool.
2. Close all of the doors.
3. Turn ON the ignition, with the engine OFF.
4. With a scan tool, observe the appropriate Door Ajar Switch parameter in the body control module (BCM) data list.

Does the scan tool display Door Ajar?

Go to Step 5

Go to Step 11

1. With a scan tool, observe the appropriate Door Ajar Switch parameter in the BCM data list.
2. Disconnect each of the door lock harness connectors, one at a time.

Does the scan tool display change to Door Closed when any of the door lock harness connectors are disconnected?

Go to Step 12

Go to Step 8

1. Install a scan tool.
2. Open all of the doors.
3. Turn ON the ignition, with the engine OFF.
4. With a scan tool, observe the appropriate door ajar switch parameter in the BCM data list.

Does the scan tool display Door Ajar?

Go to Step 11

Go to Step 7

1. Turn OFF the ignition.
2. Disconnect the appropriate door lock harness connector.
3. Connect a 3-amp fused jumper wire between the front door ajar switch signal circuit of the appropriate door lock harness connector and a good ground.
4. Turn ON the ignition, with the engine OFF.

Does the door ajar indicator illuminate?

Go to Step 9

Go to Step 10

Test the appropriate front door ajar switch signal circuit of the appropriate door lock harness connector for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 17
