Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Clean the Camera Lens

Locate the rear view camera, typically positioned above the license plate.
Use a soft cloth and mild cleaner to gently clean the camera lens, ensuring no smudges or dirt obstruct visibility.

3. Check and Replace Fuses

Open the fuse box cover and locate the fuse related to the rear view camera (refer to the owner's manual for the exact location).
Remove the fuse with a fuse puller and inspect it for continuity; replace with a new fuse of the same amperage if blown.

4. Inspect Wiring and Connectors

Remove any panels covering the camera wiring harness.
Check the camera connector for any signs of corrosion or loose connections.
If a loose connection is found, reconnect securely; if corroded, clean with electrical contact cleaner.

5. Test Camera Voltage

Reconnect the battery and use a multimeter set to DC voltage.
Measure the voltage at the camera connector while the vehicle is in reverse; it should read approximately 12 volts. If not, trace back to the display unit and check for continuity in the wiring.

6. Reassemble Components

Reattach any panels or coverings that were removed during inspection.
Ensure all tools are accounted for and the work area is clean.
