Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Clean the Camera Lens

Locate the backup camera mounted above the rear license plate.
Use a soft cloth and mild cleaner to gently wipe the lens free of dirt or debris.
Reconnect the battery and test the camera before proceeding.

3. Inspect and Replace Fuses

Open the fuse box located under the dashboard or under the hood (refer to the owner's manual for exact location).
Identify the fuse associated with the backup camera system (typically marked as "Back Up" or "Rear Camera").
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage (usually 7.5A).
Reconnect the battery and test the camera.

4. Check and Repair Connections

Remove the interior panels to access the backup camera wiring harness.
Inspect the connectors for corrosion or damage.
If any connections are loose or damaged, reconnect securely or replace the connector as necessary.
Reassemble the panels and test the camera.

5. Test Power Supply to the Camera

With the vehicle in reverse, use a multimeter to check the voltage at the backup camera connector.
Ensure it reads approximately 12V. If not, trace the wiring back to the multimedia unit for faults.
Repair any damaged wiring or connectors identified during the inspection.

6. Reset Infotainment System

If the camera is still not functioning, perform a reset of the infotainment system according to the owner's manual instructions.
After resetting, test the backup camera once more.
