Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers
Disconnect the negative battery terminal to ensure safety during the repair process.

2. Inspect the Cruise Control Switch

Remove the steering column cover using a screwdriver.
Disconnect the cruise control switch connector.
Visually inspect for any damage or loose connections.
If damaged, replace the cruise control switch with a new one.

3. Check the Brake Pedal Switch

Locate the brake pedal switch, usually mounted near the top of the brake pedal.
Use a multimeter to test the switch for continuity.
If the switch does not have continuity when the pedal is pressed, replace the brake pedal switch.

4. Inspect the Cruise Control Module

Locate the cruise control module, typically found near the engine bay or under the dash.
Check for any signs of corrosion, loose wiring, or damage.
If damaged, replace the cruise control module.

5. Test the Throttle Position Sensor

Use a multimeter to check the throttle position sensor (TPS) voltage readings.
Compare the readings with the manufacturer specifications (usually between 0.5V to 4.5V).
If readings are out of range, replace the throttle position sensor.

6. Verify Vehicle Speed Sensor

Inspect the vehicle speed sensor for any signs of damage or disconnection.
Use a multimeter to test the sensor's output.
If the speed sensor is faulty, replace it with a new one.
