Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, screwdriver set, and cleaning supplies.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean Camera

Locate the rearview camera, usually mounted on the trunk or rear hatch.
Use a soft cloth and some glass cleaner to gently clean the camera lens, removing any dirt or obstructions.
Reconnect the battery and test the camera functionality.

3. Check Reverse Light Functionality

If the camera is still not working, inspect the reverse light bulbs.
Remove the reverse light assembly and check for burned-out bulbs; replace if necessary.
Test the reverse lights by putting the vehicle in reverse and checking if they illuminate.

4. Inspect Wiring and Connections

Remove any panels or covers to access the wiring harness connected to the rearview camera.
Check for frayed wires, corrosion, or loose connections and repair or replace as needed.

5. Test Camera Power Supply

With the multimeter, check the voltage at the camera connector while the vehicle is in reverse.
Ensure it is receiving approximately 12 volts. If not, trace the wiring back to the source for faults.
