Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure vehicle is parked on a flat surface, and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean the Camera

Locate the rearview camera on the tailgate.
Remove any dirt or obstructions using a soft cloth and mild cleaner.
Confirm that the camera lens is clear and not cracked.

3. Check and Replace the Fuse

Locate the fuse box under the dashboard and/or in the engine compartment.
Identify the fuse corresponding to the rearview camera (refer to the owner’s manual).
Remove the fuse and inspect it; replace it if blown with a fuse of the same amperage.

4. Inspect Wiring Connections

Remove the panel covering the rear camera wiring (if applicable).
Check the connectors for any signs of corrosion or damage.
Tighten any loose connections; replace connectors if necessary.

5. Test the Camera Voltage

Reconnect the battery and turn on the ignition (do not start the engine).
Use a multimeter to check voltage at the camera connector; it should read approximately 12V.
If no voltage is detected, trace wiring back to the display unit for further inspection.

6. Software Reset (if applicable)

If the camera is still unresponsive, perform a reset on the multimedia system.
Disconnect the vehicle battery for about 10 minutes and reconnect it.
Start the vehicle and check if the camera functions properly upon engaging reverse.
