Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect Camera and Connections

Camera Inspection:
- Clean the camera lens with a soft cloth.
- If any damage is present, replace the camera assembly.
Connection Check:
- Remove the rear camera cover using a flathead screwdriver.
- Inspect the wiring harness for loose connections or frayed wires.
- Secure any loose connections and repair any damaged wires.

3. Fuse Check

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse related to the rear view camera (refer to the owner’s manual).
Use a fuse puller to remove the fuse and inspect it; replace if blown.
Reinstall the fuse and ensure it is firmly seated.

4. Voltage Testing

Reconnect the camera harness if previously disconnected.
Turn on the vehicle’s ignition without starting the engine.
Use a multimeter to check voltage at the camera connector; it should read approximately 12V.
If no voltage is detected, trace the wiring back to the fuse box for any breaks.

5. Reprogram or Reset Infotainment System

If all hardware appears functional, reset the infotainment system by disconnecting the battery for 10 minutes.
Reconnect the battery and check if the rear view camera activates upon engaging reverse.
