Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the vehicle battery to prevent any electrical shorts during repair.

2. Inspect and Replace Fuse

Locate the fuse box (refer to the owner's manual for specific location).
Remove the fuse associated with the rearview camera using a fuse puller.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Check Camera Connections

Remove the rear trim panel to access the camera wiring harness.
Inspect the wiring for signs of wear, corrosion, or disconnection.
Reconnect any loose wires and secure the connections.

4. Test Camera Voltage

Reconnect the battery.
Turn the ignition to the "ON" position without starting the engine.
Use a multimeter to measure voltage at the camera connector; it should typically read around 12V.
If no voltage is present, trace wiring back to the source for additional issues.

5. Replace Camera (if necessary)

If the camera is determined to be faulty, remove the camera from the vehicle.
Disconnect the wiring harness from the camera.
Install the new camera by connecting the wiring harness and securing it in place.
Reassemble the rear trim panel.
