Fixing Rearview Camera Malfunction in 2019 Chevrolet Silverado 1500

Required Tools

OBD-II Scanner
Multimeter
Basic hand tools (screwdrivers, pliers, sockets)
Wrench set
Cleaning supplies (microfiber cloth, automotive cleaner)
Replacement camera (if necessary)

Repair Instructions

Step 1: Clean the Camera Lens

Use a microfiber cloth and automotive cleaner to clean the camera lens.
Ensure no obstructions are blocking the camera view.

Step 2: Inspect and Repair Wiring

Remove the tailgate trim panel to access the camera wiring.
Inspect the wiring harness for any frayed wires or loose connections.
Repair or replace any damaged wiring using solder and heat shrink tubing or appropriate connectors.

Step 3: Test Camera Power and Ground

Disconnect the camera from the wiring harness.
Connect the multimeter leads to the camera connector:
- Red lead to the power wire (usually the red or yellow wire).
- Black lead to the ground wire (usually black or brown).
While a helper puts the vehicle in reverse, check for voltage. If present, the wiring to the camera is likely fine. If not, you may have a fault in the wiring or the BCM (Body Control Module).

Step 4: Replace the Camera (if necessary)

If the camera is faulty, remove the old camera by unscrewing it from its mount.
Disconnect the wiring harness from the camera.
Connect the new camera to the wiring harness.
Mount the new camera and secure it in place with screws.

Step 5: Reassemble and Test

Reinstall the tailgate trim panel.
Start the vehicle and put it in reverse to test the new camera.
Ensure the camera image displays correctly on the infotainment screen.
If the error persists, recheck connections and consider resetting the infotainment system again.

Conclusion

If all steps have been followed and the rearview camera still does not function, further diagnosis may be needed, potentially involving the BCM or the infotainment unit itself. If necessary, consult the dealership or a certified technician for advanced troubleshooting.
