Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic socket set, cleaning cloth, and lens cleaner.
Ensure the vehicle is parked on a level surface and is in "Park" mode.

2. Clean the Camera Lens

Using a cleaning cloth and lens cleaner, gently wipe the camera lens.
Inspect for any physical damage or obstructions. If damaged, consider replacing the camera.

3. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual for exact location).
Identify the fuse associated with the backup camera (check the diagram on the fuse box cover).
Remove the fuse using a fuse puller and inspect it for continuity; replace if blown with a fuse of the same amperage.

4. Inspect and Repair Wiring

Access the wiring harness connected to the backup camera.
Inspect for any signs of wear, fraying, or corrosion.
Repair any damaged wires using electrical tape or heat-shrink tubing. Ensure connections are secure.

5. Test Camera Voltage

Set the multimeter to DC voltage.
Connect the multimeter probes to the camera power connector.
With the vehicle in reverse, check that the voltage reading is within the manufacturer specifications (typically around 12V).
If voltage is low or absent, trace the wiring back to the source and repair any issues.

6. Reset the Infotainment System

If all hardware components are functioning, reset the vehicle’s infotainment system.
Disconnect the vehicle battery for about 10 minutes to reset the system.
Reconnect the battery, turn on the ignition, and test the backup camera.
