If the camera is determined to be faulty, replace it with a new unit:
- Disconnect the old camera, noting the connections.
- Connect the new camera, ensuring secure connections.
If wiring damage is found, repair or replace the damaged sections:
- Use a soldering kit for wire repairs or replace the entire harness if necessary.
