1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Clean the Camera Lens

Sub-steps:
1. Locate the backup camera at the rear of the vehicle, typically above the license plate.
2. Gently clean the camera lens with a soft cloth and a mild cleaner to remove dirt or debris.
3. Reconnect the battery terminal after cleaning.

Sub-steps:
1. Remove any trim panels or covers to access the wiring harness connected to the backup camera.
2. Check for loose, damaged, or corroded connectors and wiring.
3. If any damage is found, repair or replace the affected wiring or connectors as necessary.

4. Test Power Supply

Sub-steps:
1. Set the multimeter to measure DC voltage.
2. Locate the power wire for the backup camera connection.
3. With the vehicle in reverse, probe the power wire to check for proper voltage (typically around 12V).
4. If voltage is absent, trace back to the fuses and check for any blown fuses or faulty components.

5. Reprogram or Reset Infotainment System

Sub-steps:
1. With the vehicle running, access the vehicle settings from the infotainment system.
