Go to Diagnostic System Check - Retained Accessory Power

2

1. Close all the doors.
2. Wait 25 seconds.

Are the interior lights still ON?

Go to Courtesy or Dome Lamps Always On in Lighting Systems

Go to Step 3

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. Observe the remote function actuator (RFA) Accessory 1 status.

Does the Accessory 1 status indicate Off?

Go to Step 4

Go to Step 14

Observe the RAP Output parameters in the RFA data list.

Does the RAP Output indicate ON?

Go to Step 5

Go to Step 15

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 11

Go to Step 6

1. Turn OFF the ignition.
2. Disconnect the RAP relay.
3. Turn ON the ignition, with the engine OFF.
4. 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 7

Go to Step 16

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 11

Go to Step 8

Does the test lamp remain illuminated with each command?

Go to Step 10

Go to Step 9

Test the control circuit of the RAP relay for a high resistance, an open or a short to voltage (B+). Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 15

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?

Go to Step 19

Go to Step 15

Test the load output circuit of the RAP relay for a short to ground, high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 12

Test the load input circuit of the RAP relay for a short to ground, high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 13

Inspect for poor connections/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 19

Go to Step 17

Test the RFA ignition positive voltage circuit for a short to ground, a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 19

Go to Step 15

Inspect for poor connections/terminal tension at the harness connector of the RFA. 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 19

Go to Step 18

Repair the coil side feed circuit of the RAP relay. Refer to Wiring Repairs in Wiring Systems.

Did you complete the repair?
