Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, Phillips screwdriver, and electrical tape.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical shorts while working.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the cruise control fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Test the Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal.
Disconnect the electrical connector from the brake pedal switch.
Use a multimeter to test the switch: it should show continuity when the pedal is pressed and no continuity when released.
If faulty, replace the brake pedal switch.

4. Check and Replace Cruise Control Switch

Remove the steering wheel cover to access the cruise control switch.
Disconnect the wiring harness from the switch.
Test the switch for continuity using a multimeter. If it fails, replace the switch.
Reassemble the steering wheel cover after replacement.

5. Verify Speed Sensor Function

Locate the vehicle's speed sensor, usually near the transmission.
Disconnect the sensor and test it with a multimeter to ensure it is sending a signal.
If the sensor is not functioning, replacement is necessary.

6. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Start the vehicle and test the cruise control system to ensure it operates correctly.
