Solution

1. Preparation

Gather necessary tools (screwdriver set, multimeter, OBD-II scanner).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Identify the fuse related to the backup camera (typically labeled as "Rear View Camera").
Remove the fuse using a fuse puller or pliers; inspect it visually for damage.
Replace with a new fuse of the same amperage if blown.

3. Check Camera Connections

Access the rear camera by removing any panels or covers as necessary.
Inspect the camera connector for corrosion or loose connections.
Disconnect and reconnect the camera connector to ensure a secure fit.

4. Test Voltage Supply

With the multimeter, test the voltage at the camera connector while the vehicle is in reverse.
Ensure the reading is within the manufacturer's specifications (typically around 12V).
If the voltage is not present, trace the wiring back to the infotainment system to identify any breaks or shorts.

5. Software Reset

Reconnect the vehicle battery.
Start the vehicle and use the OBD-II scanner to clear any stored error codes.
Check the infotainment settings to ensure the backup camera is enabled.
