  • Ensure the vehicle is parked on a flat surface with the ignition off.
2. Inspect the Cruise Control Switch
  • Remove the steering column cover using a socket set.
  • Disconnect the cruise control switch connector.
  • Inspect the switch for damage or wear; test continuity using a multimeter.
  • Replace the switch if faulty.
3. Test the Brake Pedal Switch
  • Locate the brake pedal switch, usually mounted above the brake pedal.
