Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Inspect Backup Camera

Remove any obstructions from the camera lens.
If dirty, clean the lens with a soft cloth and mild cleaner.
Reconnect the battery and check if the image returns.

3. Check Fuses

Locate the fuse box in the vehicle (typically under the dashboard or in the engine compartment).
Identify the fuse for the backup camera using the diagram.
Remove the fuse using pliers and visually inspect it for signs of damage.
Replace with a new fuse of the same amperage if blown.

4. Inspect Wiring Connections

Remove the trim panel covering the backup camera wiring.
Visually inspect the wiring for frays, corrosion, or disconnections.
If any damage is found, repair or replace the wiring as necessary.

5. Test Power to Camera

Use a multimeter to check for voltage at the camera connector while the vehicle is in reverse.
If no voltage is present, trace back to the source to locate the fault.
Repair any broken connections.
