Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Rear View Camera
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
The hardwired circuits of the Rear View Camera (RVC) and those between the RVC and the radio receiver may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the RVC or the radio receiver. The most reliable, efficient and accurate means to diagnose the electronic controls and communication related to radio receiver operation, as well as the retrieval or erasure of a DTC requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
Be certain to confirm both of the following prior to attempting any further diagnosis or testing of the RVC. Use a diagnostic scan tool to confirm the rear view camera is setup in the vehicle configuration. From the initial start up screen of the diagnostic scan tool, navigate to >>ECU VIEW<<, select >>TIPMCGW CENTRAL GATEWAY<<, >>MORE OPTIONS<<, ECU DETAILS and then >>CONFIG INFO<<. Verify that >>REAR CAMERA PRESET - - - - SET<< is present. If not, the Sales Code XAC (Park View Rear Back-Up Camera) will have to be added to the vehicle configuration to enable the RVC, in vehicles equipped with a MyGIG multimedia entertainment system (Sales Codes RE1, REN, REP, RER, REU, REW, REX or REZ), be certain that the RVC is set to >>ENABLED<< using the >>CAMERA SETUP<< option in the MyGIG system settings.
| CONDITION | POSSIBLE CAUSES | CORRECTION |
|---|---|---|
| NO VIDEO DISPLAY IN RADIO - DOES NOT DISPLAY >>CHECK ENTIRE SURROUNDINGS<< MESSAGE BRIEFLY AFTER SHIFTING INTO REVERSE | 1. Incorrect radio software. | 1. Check to be certain that the radio has the latest software update installed. Install the radio software update if required. |
| 2. Ineffective radio fuse. | 2. Test and replace the radio fuses if required. | |
| 3. Ineffective radio ground circuit. | 3. Check for loose or damaged wiring connections at the radio. Test and repair the open radio ground circuit if required. | |
| 4. Ineffective radio feed circuit. | 4. Check for loose or damaged wiring connections at the radio. Test and repair the open radio feed circuit if required. | |
| 5. Ineffective radio inputs or outputs. | 5. Use a diagnostic scan tool to test the radio inputs and outputs including those received over the CAN data bus. Refer to the appropriate diagnostic information. | |
| 6. Ineffective radio. | 6. Use a diagnostic scan tool to test the radio. Refer to the appropriate diagnostic information. | |
| NO CAMERA IMAGE IN RADIO VIDEO DISPLAY AND NO BACKUP LAMPS IN REVERSE | 1. Left backup lamp inoperative, right backup lamp okay. | 1. Test and repair the open backup lamp switch output circuit between the right and left tail lamps if required. |
| 2. Both backup lamps inoperative. | 2. Test and repair the open backup lamp switch output circuit between the Totally Integrated Power Module (TIPM) and the tail lamps if required. | |
| 3. Ineffective TIPM inputs or outputs. | 3. Use a diagnostic scan tool to test the TIPM inputs and outputs. Refer to the appropriate diagnostic information. | |
| NO CAMERA IMAGE IN RADIO VIDEO DISPLAY - DOES DISPLAY >>CHECK ENTIRE SURROUNDINGS<< MESSAGE BRIEFLY AFTER SHIFTING INTO REVERSE AND BACKUP LAMPS DO OPERATE | 1. Ineffective camera ground circuit. | 1. Check for loose or damaged wiring connections at the camera, liftgate light bar and liftgate. Test and repair the open camera ground circuit if required. |
| 2. Ineffective camera feed (backup lamp switch output) circuit. | 2. Check for loose or damaged wiring connections at the camera, liftgate light bar and upper liftgate opening header. Test and repair the open camera feed (backup lamp switch output) circuit if required. | |
| 3. Ineffective camera shield circuit. | 3. Check for loose or damaged wiring connections at the camera, liftgate light bar, upper liftgate opening header, right cowl side inner panel and radio. Test and repair the open or shorted camera shield circuit if required. | |
| 4. Ineffective camera return circuit. | 4. Check for loose or damaged wiring connections at the camera, liftgate light bar, upper liftgate opening header, right cowl side inner panel and radio. Test and repair the open or shorted camera feed circuit if required. | |
| 5. Ineffective camera signal circuit. | 5. Check for loose or damaged wiring connections at the camera, liftgate light bar, upper liftgate opening header, right cowl side inner panel and radio. Test and repair the open or shorted camera signal circuit if required. | |
| 6. Ineffective camera. | 6. Replace the ineffective camera if required. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
