Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the vehicle's battery to ensure safety while working on electrical components.
2. Inspect Cruise Control Switch
  • Tools Required: Screwdriver set, multimeter.
  • Remove the steering wheel cover to access the cruise control switch.
  • Use a multimeter to test the switch for continuity when engaged.
  • Replace the cruise control switch if defective.
3. Test Brake Pedal Switch
  • Tools Required: Multimeter.
  • Locate the brake pedal switch and disconnect the wiring harness.
  • Use a multimeter to check for continuity when the brake pedal is depressed.
  • If the switch does not function properly, replace it.
4. Examine Throttle Position Sensor
  • Tools Required: Multimeter, wrench set.
  • Locate the throttle position sensor (TPS) on the throttle body.
  • Disconnect the TPS connector and check voltage output with a multimeter.
  • If readings are outside the specified range (refer to the vehicle service manual), replace the TPS.
5. Verify Vehicle Speed Sensor (VSS)
  • Tools Required: Multimeter, socket set.
  • Locate the VSS, typically on the transmission.
  • Disconnect the sensor and test it for proper voltage output and signal.
  • If faulty, replace the VSS.
