Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean the Camera

Remove the camera housing if necessary (consult repair manual for specific instructions).
Clean the camera lens using a microfiber cloth and appropriate lens cleaner.
Reattach the camera and verify it is securely mounted.

3. Check Wiring and Connections

Visually inspect the wiring harness leading to the backup camera for frays or cuts.
Disconnect the camera connector and inspect for corrosion or bent pins.
Use electrical contact cleaner on the connectors if corrosion is present.

4. Test Voltage Supply

Reconnect the battery and turn the ignition to the "On" position without starting the engine.
Set the multimeter to measure DC voltage and connect the probes to the camera connector terminals.
Verify that the voltage reading is within the manufacturer's specifications (typically around 12V).

5. Replace Faulty Components

If the camera or wiring is damaged, replace the defective camera or wiring harness as needed.
Ensure all connections are secure and reassemble any removed parts.
