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 fault 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 the doors.
3. Turn ON the ignition, with the engine OFF.
4. With a scan tool, observe the Door Ajar Switches parameter in the body control module (BCM) data list.

Does the scan tool display Inactive?

Go to Step 5

Go to Step 10

1. Close all the doors.
2. With a scan tool, observe the driver door open sw., the Passenger Door Open Sw., and the Rear Door Open Switch parameters in the BCM data list.

Does the scan tool display Inactive for all parameters?

Go to Step 15

Go to Step 11

1. Install a scan tool.
2. Close all of the doors.
3. With a scan tool, observe the Door Ajar Switches parameter in the BCM Input data list.
4. Open, then close each door, one door at a time.

Did the scan tool display Active when any of the doors were open?

Go to Step 7

Go to Step 8

1. Close all of the doors.
2. With a scan tool, observe the driver door open sw., the Passenger Door Open Sw., and the Rear Door Open Switch parameters in the BCM Input data list.
3. Open, then close each door, one door at a time.

Did the scan tool display Active when any of the doors were open?

Go to Step 15

Go to Step 9

1. Disconnect the BCM harness connector C2.
2. Probe the door ajar switch signal circuit with a test lamp connected to battery positive voltage.
3. Open, then close each door, one door at a time.

Did the test lamp illuminate when any of the doors were open?

Go to Step 16

Go to Step 12

1. Disconnect the BCM harness connector C2.
2. Probe each of the appropriate door open switch signal circuits with a test lamp connected to battery positive voltage.
3. Open, then close each of the appropriate doors, one door at a time.

Did the test lamp illuminate when any of the doors were open?

Go to Step 16
