Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle battery to avoid electrical shorts.
Tools Required: Screwdriver set, panel removal tool, multimeter, OBD-II scanner.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Use the fuse diagram to identify the backup camera fuse.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown, replace it with a fuse of the same amperage.

3. Inspect Wiring and Connectors

Remove the rear trim panel to access the camera wiring harness.
Visually inspect the wiring for any frays, cuts, or corrosion.
Ensure that all connectors are fully seated and free of dirt or debris.
If any damage is found, repair or replace the wiring as necessary.

4. Test Camera Functionality

Reconnect the camera and battery.
Shift the vehicle into reverse and check if the camera activates.
If still non-responsive, measure the voltage at the camera connector using a multimeter.
- Ensure the camera is receiving power; if not, trace the wiring back to the source.

5. Software Reset

If the camera is powered but still non-responsive, perform a soft reset of the infotainment system.
Disconnect the vehicle battery for about 10 minutes, then reconnect.
Test the camera again after the reset.
