Go to Step 2

Go to Diagnostic System Check - Retained Accessory Power

1. Install a scan tool.
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. Operate the components that have voltage supplied by the RAP relay.

Do the components operate?

Go to Step 3

Go to Testing for Intermittent Conditions and Poor Connections

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 a scan tool, in the RIM output controls menu 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 a scan tool, in the RIM output controls menu 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

Go to Step 10

Test the control circuit of the RAP relay for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?
