Symptoms:

Distorted or poor-quality image when the camera is activated.
Camera remains stuck on the screen even when the vehicle is not in reverse.

Tools Required

Repair Instructions

Step 1: Inspect and Clean the Camera

Locate the rearview camera, typically mounted above the license plate.
Use a soft cloth and glass cleaner to gently clean the camera lens.
Ensure that there are no obstructions blocking the camera view.

Step 2: Verify Camera Activation

Shift the gear into reverse and observe the infotainment display.
If the camera does not activate, proceed to check wiring.

Step 3: Check Wiring and Connectors

Open the tailgate and locate the wiring harness leading to the rearview camera.
Inspect the wiring for damage or corrosion. If any issues are found, repair or replace the affected wires.
Ensure all connectors are tight and free from corrosion. Clean any corroded contacts with electrical cleaner.

Step 4: Use an OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve any DTCs that may indicate a malfunction in the camera or associated systems.
If a specific code indicates a fault (e.g., U0401 - Invalid Data Received), refer to the service manual for detailed troubleshooting steps related to that code.

Step 5: Perform a System Reset

Turn off the vehicle and disconnect the battery for about 10 minutes to reset the system.
Reconnect the battery and start the vehicle.

Step 6: Test for Functionality

Shift into reverse and check if the rearview camera activates correctly on the infotainment display.
If the camera is still not functioning, further inspection may be required, including checking for faults in the infotainment system or camera module.

Step 7: Replace the Camera (if necessary)

If all previous steps are completed and the camera still does not work, it may need replacement.
Remove the old camera:
- Use the appropriate Torx socket to remove the screws holding the camera in place.
- Disconnect the camera wiring harness.
Install the new camera:
- Connect the wiring harness to the new camera.
- Secure the camera in place with screws.
Test the new camera by shifting into reverse and verifying the display.

Conclusion

If the rearview camera is still malfunctioning after following these steps, consider consulting a professional technician or visiting a Chevrolet dealership for further diagnosis, as deeper issues within the infotainment system or vehicle wiring harness may require specialized tools and expertise.
