  • Ensure the vehicle is parked on a level surface and the engine is turned off before starting any repairs.
2. Check Electrical Connections
  • Disconnect the battery to ensure safety while working on electrical components.
  • Inspect the wiring harness and connectors associated with the cruise control system for damage or corrosion.
  • Clean any corroded connections with an appropriate electrical contact cleaner.
3. Inspect Brake and Accelerator Pedal Sensors
  • Locate the brake pedal sensor and ensure it is functioning correctly by testing it with a multimeter.
    • Sub-steps:
      • Remove the plastic cover from the brake pedal assembly.
      • Disconnect the sensor wiring harness.
      • Use a multimeter to check for continuity when the pedal is pressed.
      • Replace the sensor if it shows no continuity.
  • Repeat the process for the accelerator pedal position sensor.
4. Replace Fuses if Necessary
  • Locate the fuse box and identify the fuse related to the cruise control system using the owner's manual.
  • Remove the fuse and inspect it for continuity.
