What causes the reverse light not to light up and the reverse camera not to display?

[StevenLynn]

The possible causes and solutions for the reverse light not lighting up and the reverse camera not displaying are as follows: 1. Display settings issue: There is usually a camera switch control in the display settings, which should be set to "ON." 2. Camera malfunction: Inspect and replace the camera if necessary. 3. Wiring issue: This is the most common problem. The wiring harness for the reverse camera runs from the dashboard to the trunk, which is a long distance, and it's likely that a wire or connector is not making proper contact. A thorough inspection is needed. 4. Scratched reverse camera: Most camera surfaces are fragile, so it's advisable to apply a protective film over the camera. 5. Poor-quality reverse camera.
