Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to avoid electrical short circuits during repairs.
2. Replace Cruise Control Fuse
  • Locate the fuse box, typically under the dashboard or in the engine compartment.
  • Identify the cruise control fuse using the diagram on the fuse box cover.
  • Remove the faulty fuse with a fuse puller or pliers.
  • Insert a new fuse of the same amperage rating.
3. Inspect and Replace Brake Pedal Switch
  • Locate the brake pedal switch, usually mounted on the brake pedal assembly.
  • Disconnect the electrical connector from the switch.
  • Test the switch for continuity using a multimeter.
  • If faulty, remove the switch by unscrewing it from the assembly.
  • Install the new brake pedal switch and reconnect the electrical connector.
4. Test Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body.
  • Disconnect the wiring harness from the TPS.
  • Use a multimeter to measure the resistance across the TPS terminals while manually moving the throttle plate.
  • If the readings are out of specifications, replace the TPS.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle and test the cruise control system to ensure it functions correctly.
