Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers.
Ensure the vehicle is parked on a flat surface with the ignition turned off.

2. Inspect Camera Lens

Locate the rearview camera, usually mounted near the tailgate.
Clean the lens using a soft cloth and automotive glass cleaner to remove any dirt or obstruction.

3. Check the Fuse

Open the fuse panel, typically located under the dashboard or in the engine compartment.
Locate the fuse designated for the rearview camera (refer to the owner's manual for the exact location).
Inspect the fuse and replace it if it is blown.

4. Verify Wiring Connections

Remove the rearview camera assembly from its mount.
Inspect the wiring harness for any visible damage or corrosion.
Ensure all connections are secure; reconnect any loose wires.

5. Test Voltage Supply

Using a multimeter, check for voltage at the camera connector while the vehicle is in reverse.
Confirm that the voltage matches the manufacturer specifications (usually around 12V).
If no voltage is detected, trace the wiring back to the infotainment unit.

6. Reset Infotainment System

Disconnect the vehicle battery for about 10 minutes to reset the infotainment system.
Reconnect the battery, then start the vehicle and check if the rearview camera displays correctly.
