Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse associated with the backup camera (consult the owner’s manual).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage.

3. Check Camera Connections

Remove the rear panel or trim to access the camera wiring.
Inspect the camera harness for any signs of wear, corrosion, or damage.
Reconnect any loose connectors and ensure they click securely into place.

4. Test the Backup Camera

Reconnect the battery and start the vehicle.
Shift the vehicle into reverse and check if the backup camera activates.
If the display is still not functioning, proceed to test with a multimeter.

5. Multimeter Testing

Disconnect the camera harness.
Use a multimeter set to DC voltage to check for power at the harness connector while the vehicle is in reverse.
If there is no voltage, trace the wiring back to the source and check for continuity.

6. Camera Replacement (if necessary)

If the camera is determined to be faulty, unscrew the camera from its mount.
Disconnect the camera wiring harness.
Replace with a new camera, ensuring correct alignment and secure connections.
