Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface with the engine off and the keys removed.
Disconnect the vehicle battery to prevent electrical shorts.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers
Torque wrench

2. Inspect and Test the Cruise Control Switch

Remove the steering column trim using a screwdriver.
Disconnect the cruise control switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed.
If the switch is faulty, replace it with a new one and reconnect.

3. Check the Brake Pedal Position Sensor

Locate the brake pedal position sensor under the dashboard.
Disconnect the sensor connector and test it for proper voltage output using a multimeter while pressing the brake pedal.
If the sensor is defective, replace it.

4. Inspect the Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the sensor connector and use a multimeter to measure the voltage output.
If output is outside the manufacturer-recommended range, replace the throttle position sensor.

5. Check Fuses

Open the fuse box and locate the fuse designated for the cruise control system.
Pull the fuse out and inspect it visually and with a multimeter for continuity.
Replace any blown fuses with the same amperage rating.

6. Reconnect Battery and Test

Reconnect the vehicle battery and ensure all components are securely attached.
Start the vehicle and test the cruise control system for proper functionality.
