Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse associated with the backup camera (refer to the owner's manual for the exact location).
Inspect the fuse visually and use a multimeter to test for continuity. Replace if blown.

3. Check Wiring and Connections

Disconnect the negative battery terminal to ensure safety while working on electrical components.
Access the backup camera wiring harness, usually located near the rear of the vehicle where the camera is mounted.
Inspect for any loose connections, frayed wires, or corrosion. Repair or replace any damaged connectors or wiring.

4. Inspect Camera Assembly

Remove the backup camera from its mounting bracket by unscrewing or unclipping it.
Check the camera lens for any dirt, moisture, or physical damage that could obstruct the view.
Clean the lens with a soft, lint-free cloth if dirty. If the camera is damaged, replace it with a new unit.

5. Reconnect and Test

Reconnect all wiring and ensure connections are secure.
Reconnect the negative battery terminal.
Start the vehicle, engage the reverse gear, and check the backup camera display for proper function.
