Solution

1. Preparation

Gather tools such as a socket set, multimeter, OBD-II scanner, and cleaning materials.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean the Camera

Remove any debris blocking the camera lens.
If the lens is dirty, use a microfiber cloth and a gentle cleaning solution to clean it.

3. Check and Replace the Fuse

Locate the fuse box using the vehicle's manual.
Identify the fuse for the rearview camera (refer to the fuse box diagram).
Remove the fuse using a fuse puller or needle-nose pliers; inspect it for continuity.
Replace with a new fuse of the same amperage if the old fuse is blown.

4. Reconnect or Replace Wiring Harness

Locate the wiring harness connected to the rearview camera.
Inspect for any signs of damage or corrosion; repair if necessary.
If damaged beyond repair, replace the wiring harness with a new one.

5. Test Camera Voltage

Reconnect the battery.
With the vehicle in reverse, use a multimeter to check the voltage at the camera connector.
If no voltage is present, further investigate wiring or electrical issues.

6. Reprogram or Reset Infotainment System

If necessary, reset the infotainment system by disconnecting the battery for a few minutes and reconnecting it.
Check for software updates that may address camera functionality issues.
