1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Install a scan tool. Select the class 2 power mode parameter under the diagnostic circuit check menu. Close all the doors. Turn ON the ignition with the engine OFF. Wait 5 seconds, then turn OFF the ignition. Observe the class 2 power mode parameter under the diagnostic circuit check menu. Does the scan tool display the RAP power mode?	Go to Step 3	Go to Step 15
3	Observe the RAP Output parameter in the rear integration module (RIM) data list. Does the RAP Output indicate ON?	Go to Step 4	Go to Step 11
4	Turn ON the ignition, with the engine OFF. With the scan tool, select the RAP relay in the rear integration module (RIM) output controls menu. 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
5	Turn OFF the ignition. Disconnect the RAP relay. Turn ON the ignition, with the engine OFF. Probe the coil side feed circuit of the RAP relay with a test lamp that is connected to a good ground. Does the test lamp illuminate?	Go to Step 6	Go to Step 12
6	Connect a test lamp between the control circuit of the RAP relay and the coil side feed circuit of the RAP relay. 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 7
7	Test the control circuit of the RAP relay for a open or a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 11
8	Test the load output circuit of the RAP relay for open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 9
9	Test the load input circuit of the RAP relay for open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 10
10	Inspect for poor connections and terminal tension at the RAP relay. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 13
11	Inspect for poor connections and terminal tension at the harness connector of the RIM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 14
12	Repair the coil side feed circuit of the RAP relay. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	Go to Step 17	--
13	Replace the RAP relay. Did you complete the replacement?	Go to Step 17	--
14	Replace the RIM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	Go to Step 17	--
15	Inspect for poor connections and terminal tension at the harness connector of the dash integration module (DIM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 17	Go to Step 16
16	Replace the DIM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	Go to Step 17	--
17	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 1
