Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and electrical tape.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Camera and Connections

Camera Lens Check:
- Visually inspect the camera lens for dirt or damage. Clean if necessary.
Wiring Inspection:
- Remove the trim panel covering the camera wiring (usually located near the tailgate).
- Check for loose connectors, frayed wires, or corrosion. Repair or replace as needed.

3. Test Power Supply

Using a Multimeter:
- Set the multimeter to the DC voltage setting.
- Disconnect the camera connector and probe the harness side with the multimeter.
- Have someone shift the vehicle into reverse to check for voltage (should be around 12V). If no voltage is present, trace back to the fuse or wiring.

4. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the backup camera (refer to the owner's manual).
Remove the fuse and inspect it. If blown, replace it with a fuse of the same rating.

5. Reassemble and Test

Reconnect any disconnected wiring and ensure all connections are secure.
Reinstall any trim panels that were removed.
Test the backup camera by shifting the vehicle into reverse to see if the screen activates.
