Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the vehicle's battery to prevent electrical shock.

2. Clean the Camera Lens

Locate the rearview camera, usually mounted near the trunk or rear bumper.
Use a microfiber cloth and a mild glass cleaner to wipe the camera lens.
Inspect the lens for any cracks or damage that could affect its functionality.

3. Check and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Refer to the owner's manual to identify the fuse associated with the rearview camera.
Remove the fuse and inspect it; if blown, replace it with a fuse of the same amperage.

4. Inspect Wiring and Connectors

Carefully remove any trim panels to access the camera wiring harness.
Inspect the wires for any signs of fraying, breaks, or corrosion.
Disconnect and reconnect any connectors to ensure a secure connection.

5. Test Camera Voltage

Using a multimeter, set it to measure DC voltage.
With the vehicle in reverse, probe the camera connector's power wire to check for voltage (typically around 12V).
If no voltage is present, trace back to the source to find a break in the circuit.

6. Reconnect Battery and Test System

Reconnect the vehicle's battery.
Shift the vehicle into reverse and check if the rearview camera functions correctly.
Monitor the infotainment system for any error messages associated with the camera.
