Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and socket set.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Inspect the Cruise Control Switch

Sub-steps:
1. Remove the steering wheel cover using a screwdriver.
2. Disconnect the cruise control switch connector.
3. Use a multimeter to test the switch for continuity when pressed.
4. Replace the switch if it is faulty.

3. Check the Brake Pedal Position Switch

Sub-steps:
1. Locate the brake pedal position switch (usually near the top of the brake pedal).
2. Disconnect the wiring harness from the switch.
3. Use a multimeter to check for continuity when the brake pedal is pressed.
4. Adjust or replace the switch if it does not function correctly.

4. Inspect the Throttle Position Sensor (TPS)

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector.
3. Use a multimeter to check the voltage output while moving the throttle.
4. Replace the TPS if the voltage readings are out of specifications.

5. Examine the Cruise Control Actuator

Sub-steps:
1. Locate the cruise control actuator, typically found near the engine bay.
2. Check for any physical damage or disconnections.
3. Test the actuator by applying power directly to the connector to see if it engages.
4. Replace the actuator if it does not operate correctly.
