Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

1. Install a scan tool. Select the class 2 power mode parameter under the diagnostic circuit check menu.
2. Close all the doors.
3. Turn ON the ignition with the engine OFF.
4. Wait 5 seconds, then turn OFF the ignition.
5. Wait 10 minutes.
6. Observe the class 2 power mode parameter under the diagnostic circuit check menu.

Did the scan tool display the RAP power mode then time-out and display the OFF or OFF/AWAKE power mode?

Go to Step 3

Go to Step 13

Observe the RAP Output parameter in the rear integration module (RIM) data list.

Does the RAP Output indicate OFF?

Go to Step 4

Go to Step 10

1. Turn ON the ignition, with the engine OFF.
2. With the scan tool, command the RAP relay ON and OFF.

Does the RAP relay turn ON and OFF with each command?

Go to Step 8

Go to Step 5

1. Connect a test lamp between the control circuit of the RAP relay and the coil side feed circuit of the RAP relay.
2. With the scan tool, command the RAP relay ON and OFF.

Does the test lamp turn ON and OFF with each command?

Go to Step 8

Go to Step 6

Does the test lamp remain illuminated with each command?

Go to Step 7
