Repair Instructions

Step 1: Clean the Camera Lens

  • Tools Needed: Cleaning cloth, window cleaner.
  • Instructions:
    1. Use the cleaning cloth and window cleaner to gently clean the camera lens located on the windshield.
    2. Inspect for any obstructions and ensure the area around the camera is clear.

Step 2: Clear Diagnostic Trouble Codes

  • Tools Needed: OBD-II scanner.
  • Instructions:
    1. Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
    2. Read and note any trouble codes related to the LDW system.
    3. Clear the codes and perform a test drive to see if the issue persists.

Step 3: Inspect Camera Alignment

  • Tools Needed: Screwdriver set.
  • Instructions:
    1. If the camera is misaligned, carefully remove the mounting screws (if applicable) using a screwdriver.
    2. Adjust the camera to ensure it is level and centered.

Step 4: Check Vehicle Settings

  • Instructions:
    1. Start the vehicle and navigate to the settings menu on the infotainment system.

    3. Adjust sensitivity settings as needed.

Step 5: Test Drive
