Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, screwdrivers, and cleaning materials.
Ensure the car is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Clean Camera

Locate the backup camera, typically mounted above the license plate.
Use a soft cloth or lens cleaner to gently clean the camera lens.
Inspect the camera housing for any visible damage or obstructions.

3. Check Fuses

Open the fuse box and locate the fuse for the backup camera (refer to the owner's manual for the exact location).
Remove the fuse and inspect it; replace it if it appears blown (metal strip broken).
Reinstall the fuse and test the camera functionality.

4. Examine Wiring Connections

Remove the trim panel around the camera and display unit to access wiring.
Inspect all connector plugs for damage, corrosion, or looseness.
Secure any loose connections and clean corroded connectors with electronic cleaner.

5. Test Voltage Supply

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to measure voltage at the backup camera connector.
- Expected voltage: approx. 12V. If no voltage is present, trace back to the wiring harness for breaks or shorts.

6. Replace Backup Camera (if necessary)

If the camera is determined to be faulty, remove it from the mounting bracket.
Disconnect the wiring harness and install the new camera.
Reattach the camera and ensure it is securely mounted.
