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. Inspect and Clean the Camera

Locate the rearview camera, which is typically mounted near the trunk or rear license plate area.
Use a soft cloth to clean the camera lens gently, removing any dirt or debris that may obstruct the view.

3. Check and Replace Fuses

Open the fuse box and locate the fuse for the rearview camera (refer to the owner's manual for the specific fuse location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage; if blown, replace it with a new fuse of the same amperage.

4. Inspect Wiring Connections

Remove any covers or panels that obstruct access to the camera wiring harness.
Check all wiring connections for signs of corrosion, damage, or looseness.
If any wires are damaged, repair or replace them as necessary.

5. Test the Camera Functionality

Reconnect the negative battery terminal.
Put the vehicle in reverse and observe the infotainment display.
If the camera is still not functioning, consider replacing the rearview camera unit.

6. Reinstall Components

If any panels were removed during inspection, reinstall them securely.
Ensure all tools are removed from the vehicle before closing any compartments.
