1. VERIFY OPERATION OF THE RADIO AND BACKUP LAMPS
1. Verify the operation of the Radio and Backup Lamps.

Do the Radio and Backup Lamps operate correctly?

Yes

- Go To 2

No

- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE (L1) BACKUP LAMP SWITCH OUTPUT CIRCUIT




1. Turn the ignition off.
2. Apply the parking brake.
3. Disconnect the Rear Camera Assembly harness connector.
4. Turn the ignition on.
5. Shift the vehicle in to reverse.
6. Measure the voltage of the (L1) Backup Lamp Switch Output circuit.

Is battery voltage present?

Yes

- Go To 3

No

- Using the wiring diagrams as a guide, repair the (L1) Backup Lamp Switch Output circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. CHECK THE (Z916) GROUND CIRCUIT




1. Turn the ignition off.
2. Measure the resistance between ground and the (Z916) Ground circuit.

Is the resistance below 10.0 Ohms?

Yes

- Go To 4

No

- Using the wiring diagrams as a guide, repair the (Z916) Ground Circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. CHECK THE CAMERA SIGNAL, RETURN, AND SHIELD CIRCUITS FOR AN OPEN CIRCUIT




1. Disconnect the Radio C3 harness connector.
2. Measure the resistance of the (X970) (X971) and (X972) circuits.

Is the resistance below 10.0 Ohms on the (X970) (X971) or (X972) circuits?

Yes

- Go To 5

No

- Using the wiring diagrams as a guide, repair the appropriate circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK THE CAMERA SIGNAL, RETURN, AND SHIELD CIRCUITS FOR A SHORT TO GROUND




1. Measure the resistance between ground and the (X970) (X971) and (X972) circuits.

Is the resistance below 10.0 Ohms on the (X970) (X971) or (X972) circuits?

Yes

- Using the wiring diagrams as a guide, repair the appropriate circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Rear Camera Assembly.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
