Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent any electrical shorts during repair.

2. Clean Camera Lens

Inspect and clean the rearview camera lens with a soft cloth and automotive glass cleaner if dirty.

3. Check Fuses

Locate the fuse box (typically found under the dashboard or in the engine compartment).
Identify the fuse associated with the rearview camera (refer to the owner's manual).
Remove the fuse using a fuse puller and inspect it for continuity. Replace if blown.

4. Inspect Wiring and Connectors

Remove any panels covering the rearview camera and wiring.
Visually inspect the camera wiring for frays, breaks, or corrosion.
Disconnect and reconnect the camera harness to ensure a secure connection.

5. Test Camera Voltage

Reconnect the vehicle battery.
Use a multimeter to measure the voltage at the camera connector while the vehicle is in reverse.
Confirm that the voltage is within the acceptable range (typically around 12V). If not, trace back to the source.

6. Replace Camera (if necessary)

If all previous steps fail to resolve the issue, replace the rearview camera.
- Disconnect the old camera by removing the screws and harness.
- Connect the new camera and secure it in place.
