Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

Do only the devices powered by the RAP relay exhibit this symptom?

Go to Step 5

Go to Step 3

1. Observe the following parameters in body control module (BCM) data list:

•	Driver Door Ajar Sw.

•	Passenger Door Ajar Sw.

2. Open and close each door while observing the respective parameter.

Does the scan tool display change from Ajar to Door Closed respectively?

Go to Step 4

Go to Symptoms - Lighting Systems

1. Select diagnostic circuit check and then class 2 power mode, on the scan tool.
2. Close all of the doors.
3. Turn ON the ignition, with the engine OFF.
4. Wait 5 seconds then turn the ignition OFF.
5. Wait the time-out for retained accessory power (RAP).

Did the scan tool display the RAP power mode then time-out, and display Off-Awake power mode?

Go to Step 5

Go to Step 11

1. Turn OFF the ignition.
2. Disconnect the RAP relay.
3. Turn ON the ignition, with the engine OFF.
4. With a test lamp that is connected to a good ground, probe the battery positive voltage circuit of the RAP relay.

Does the test lamp illuminate?

Go to Step 6

Go to Step 9

1. Connect a fused wire jumper across the relay switch circuits of the RAP relay.
2. Turn the ignition ON, with the engine OFF.
3. Attempt to operate the devices powered by the RAP relay.

Do the devices powered by the RAP relay operate normally?
