Solution

1. Preparation

Gather necessary tools:
- OBD-II scanner
- Screwdriver set
- Multimeter
- Wire connectors
- Electrical tape
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use the diagram on the fuse box cover to identify the fuse associated with the backup camera.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage or breakage. Replace if necessary with the same amperage rating.

3. Inspect and Repair Wiring

Access the rear of the vehicle where the backup camera is installed.
Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
If damaged, cut the wire, strip the ends, and use wire connectors to repair the connection. Cover with electrical tape for protection.

4. Test the Backup Camera

Disconnect the camera from its wiring harness.
Use a multimeter to check for voltage at the connector when the vehicle is in reverse.
If voltage is present, connect the camera directly to a power source to test functionality. If the camera does not work, it may need replacement.

5. Reinstall and Check Display Unit

If the camera and wiring are functional, reassemble any removed panels or components.
Turn on the vehicle and engage the reverse gear to check the display function.
If the screen is still black, consider updating the display unit's software or replacing the unit if necessary.
