Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box, typically 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 and inspect it for damage.
Replace with a new fuse of the same amperage if it is blown.

3. Replace the Brake Pedal Switch

Locate the brake pedal switch, usually mounted near the top of the brake pedal.
Disconnect the wiring harness from the switch.
Remove the switch by unscrewing or unclipping it from its mount.
Install the new brake pedal switch and reconnect the wiring harness.

4. Repair or Replace the Cruise Control Switch

Remove the steering wheel cover if necessary to access the cruise control switch.
Disconnect the cruise control switch wiring harness.
Inspect the switch for any signs of wear or damage.
If defective, remove the switch from the steering wheel assembly and replace it with a new one.

5. Test Vehicle Speed Sensor

Use a multimeter to check the voltage output from the vehicle speed sensor while the car is in motion.
If the readings are outside the manufacturer's specified range, replace the vehicle speed sensor.

6. Reconnect Battery and Test

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