1	Did you perform the Diagnostic System Check - Retained Accessory Power (RAP)?	Go to Step 2	Go to Diagnostic Starting Point - Retained Accessory Power
2	Answer No to the question below if the vehicle is not provided with a RAP relay. Do only the devices powered by the RAP relay exhibit this symptom?	Go to Step 4	Go to Step 3
3	Install a scan tool. Select diagnostic circuit check and then class 2 power mode. Close all the doors. Turn ON the ignition, with the engine OFF. Wait 5 seconds then turn the ignition OFF. Wait the time-out for RAP. Did the scan tool display the RAP power mode, then time-out and display Off-Awake power mode?	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 10
4	Turn the ignition switch to the OFF position. Disconnect the RAP relay. Do the devices controlled by the RAP relay operate?	Go to Step 5	Go to Step 6
5	Repair the short to battery in the RAP relay switched output circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	Go to Step 12	-
6	Open any door. Connect a test lamp across the relay coil circuits of the RAP relay. Does the test lamp illuminate?	Go to Step 7	Go to Step 8
7	Test the RAP relay control circuit for a short to B+. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 12	Go to Step 10
8	Inspect for poor connections at the RAP relay. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 12	Go to Step 9
9	Replace the RAP relay. Did you complete the replacement?	Go to Step 12	-
10	Inspect for poor connections at the harness connector of the body control module (BCM). 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 12	Go to Step 11
11	IMPORTANT: Perform the module setup procedure, if required. Replace the BCM. Refer to Body Control Module Replacement in Body Control System.Did you complete the procedure?	Go to Step 12	-
12	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 2
