Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, cleaning supplies (glass cleaner, microfiber cloth).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Clean Camera

Locate the rearview camera at the tailgate or bumper.
Clean the lens using glass cleaner and a microfiber cloth to remove dirt or debris.
Inspect for physical damage; if damaged, replace the camera.

3. Check and Replace Fuses

Open the fuse panel located under the dashboard or in the engine compartment.
Locate the fuse labeled for the rearview camera system (refer to the owner's manual for specific fuse location).
Remove the fuse using a fuse puller or pliers; inspect for continuity.
Replace with a new fuse of the same amperage if the old fuse is blown.

4. Verify Wiring and Connections

Remove any covers or panels to access the wiring harness connected to the rearview camera.
Inspect the connections for corrosion, loose wires, or damage.
Secure any loose connections and repair any damaged wires using electrical tape or connectors.

Engage reverse gear and observe the infotainment screen for camera activation.
If the camera still does not function, consider replacing the camera unit.
