Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Clean the Camera Lens

Use a microfiber cloth and automotive glass cleaner to gently clean the camera lens.
Inspect for any physical damage; if the lens is cracked, replacement may be necessary.

3. Check Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuse for the rearview camera (refer to the fuse diagram).
Remove the fuse using a fuse puller and inspect it. Replace it if blown with the same amperage rating.

4. Inspect Wiring Connections

Access the rearview camera by removing the trim panel if necessary.
Disconnect the wiring harness from the camera and inspect for corrosion or damage.
Reconnect the harness securely and ensure no wires are pinched or exposed.

5. Test Camera Voltage

Reconnect the wiring harness and turn the ignition to the accessory position.
Using a multimeter, measure voltage at the camera connector (should be around 12V).
If no voltage is present, trace the wiring back to the infotainment unit for continuity.

6. Software Update

Connect an OBD-II scanner to the vehicle’s diagnostic port.
Check for any available software updates for the infotainment system and follow manufacturer instructions to perform the update.
