2. Check the multimedia display for any settings that may disable the camera; refer to the owner’s manual for guidance.

Step 2: Inspect the Camera Lens

Action: Check for physical obstructions or damage.
Tools Required: Microfiber cloth, possibly a step ladder or stool for access.
Instructions:
1. Visually inspect the camera lens located on the rear of the vehicle.
2. Clean the lens with a microfiber cloth if dirty.
3. Look for any cracks or damage; if damaged, the camera may need replacement.

Step 3: Check for Faulty Wiring or Connections
