Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid any electric shock or short circuits.

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 fuse diagram.
Remove the fuse using a fuse puller and inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

3. Check Brake Pedal Switch

Locate the brake pedal switch, usually mounted on the brake pedal assembly.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity when the brake pedal is pressed.
If the switch is faulty, remove it by unfastening any screws or clips, then replace it with a new switch.

4. Inspect Cruise Control Stalk

Remove the steering wheel cover by unscrewing the screws and gently prying it away.
Inspect the cruise control stalk for any signs of damage or wear.
If damaged, remove the stalk by unscrewing it from the steering column and replace it with a new one.

5. Verify Vehicle Speed Sensor

Locate the vehicle speed sensor, usually found on the transmission.
Disconnect the sensor connector and remove the sensor.
Test the sensor using a multimeter to check for proper voltage output when the vehicle is in motion.
Replace the sensor if it fails the test.

6. Reconnect and Test

Reconnect the battery and start the vehicle.
Test the cruise control system to ensure it engages and maintains speed properly.
