Rearview Camera Malfunction in 2020 Chevrolet Silverado 1500 T1XX

Tools Required

OBD-II scanner
Multimeter or test light
Screwdrivers (Phillips and flat-head)
Trim removal tool
Torque wrench (if needed for reassembly)
Cleaning cloth and isopropyl alcohol (for lens cleaning)

Repair Instructions

Step 1: Visual Inspection

Examine the Camera Lens: Clean the camera lens with a cloth and isopropyl alcohol. Ensure there are no obstructions.
Inspect the Surrounding Area: Look for physical damage or dirt that could obstruct the camera.

Step 2: Check Wiring and Connectors

Access the Camera:
- Open the tailgate and remove the plastic cover or trim around the camera. Use a trim removal tool to avoid damaging the clips.
Inspect Connections:
- Check the camera connector for corrosion or loose connections.
- Ensure the wiring harness is securely connected to the camera and the vehicle harness.
Test Voltage:
- Using a multimeter, check for voltage at the camera harness connector when the vehicle is in reverse. You should see power (typically around 12V).
- If there’s no power, trace the wiring back to the fuse box.

Step 3: Scan for Diagnostic Trouble Codes (DTCs)

Connect OBD-II Scanner:
- Plug in the OBD-II scanner under the dashboard.
Read Codes:
- Navigate to the "Body" or "Camera" module to check for any stored codes. Notable codes may include U0191 (lost communication with rearview camera).
Clear Codes:
- If any codes are found, clear them and test the camera system again.

Step 4: Replace the Camera (if necessary)

Remove the Old Camera:
- If the camera is confirmed faulty, disconnect the wiring harness and remove the camera from its mount, typically secured with screws.
Install the New Camera:
- Position the new camera in place and secure it with screws.
- Reconnect the wiring harness ensuring a snug fit.
Reassemble Trim:
- Replace the camera trim and ensure all clips are secured.

Step 5: Re-check Functionality

Test the System:
- Start the vehicle and shift into reverse. Check if the rearview camera displays correctly.
- Ensure all features associated with the camera, such as guidelines, are functioning as intended.

Step 6: Document and Finalize

Document Repairs:
- Note down any repairs completed and any parts replaced for future reference.
Final Inspection:
- Perform a quick check of the entire system to ensure everything is functioning properly.

Conclusion

If the issue persists after following these steps, further diagnosis may be required, potentially involving a deeper inspection of the vehicle's infotainment system or a visit to a professional technician.
