Step 4: Inspect Wiring (If Necessary)

  1. Visual Inspection:

    • If the ACC is still not available, perform a visual inspection of the wiring harness and connectors associated with the radar and cameras.
    • Look for any signs of damage, corrosion, or loose connections.

  2. Reconnect or Repair:

    • If you find any issues, disconnect the wiring, clean the contacts, and reconnect to ensure a good electrical connection.
