Repair Instructions

1. Addressing Obstructions and Cleaning the Radar Sensor

  • Step 1: Open the hood and locate the front radar module.
  • Step 2: Remove any debris, dirt, or ice that may be obstructing the sensor.
  • Step 3: Clean the radar sensor lens with a soft cloth and appropriate cleaner.

2. Checking and Repairing Wiring

  • Step 1: Inspect the wiring harness leading to the radar module for damage.
  • Step 2: Use a multimeter to check for continuity in the wires.
  • Step 3: Repair or replace any damaged wires or connectors.

3. Resetting or Replacing the Cruise Control Switch

  • Step 1: Remove the steering wheel airbag (ensure to disconnect the battery before this step).
  • Step 2: Access the cruise control switch assembly.
  • Step 3: Test the switch with a multimeter for continuity.
  • Step 4: Replace the switch if it is faulty and reassemble the steering wheel.

4. Recalibrating the Radar Sensor
