how can I solve the reversing camera that won't display in my Volkswagen Tiguan?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe and stable position.
• Disconnect the vehicle battery to avoid electrical shorts.

2. Inspect and Replace Fuse

• Locate the fuse box and identify the fuse for the reversing camera.
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Inspect Wiring and Connectors

• Remove any necessary panels to access the wiring harness leading to the camera.
• Visually inspect the wiring for frays, cuts, or corrosion.
• Clean or replace any damaged connectors.

4. Test and Replace Camera

• If wiring is intact, disconnect the camera connector.
• Use a multimeter to test the camera for proper voltage when the vehicle is in reverse.
• If no voltage is present or the camera is not functioning, replace the rearview camera with a new one.
• Connect the new camera and secure it in place.

5. Reconnect Battery and Test

• Reconnect the vehicle battery.
• Start the vehicle and shift into reverse to check if the camera displays correctly on the infotainment screen.
