Solution

1. Preparation

Gather tools and necessary equipment.
Ensure the vehicle is parked on a level surface with the engine turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect the Brake Pedal Switch

Locate the brake pedal switch, which is usually mounted above the brake pedal.
Remove the connector from the brake pedal switch.
Use a multimeter to test the switch for continuity. The switch should close when the brake pedal is pressed.
If the switch is faulty, replace it with a new component.

3. Check the Cruise Control Switch

Remove the steering column covers to access the cruise control switch.
Inspect the switch for wear or damage.
If necessary, disconnect the electrical connector and test the switch with a multimeter.
Replace the cruise control switch if it’s not functioning properly.

4. Inspect the Vehicle Speed Sensor (VSS)

Locate the VSS, typically found on the transmission.
Disconnect the wiring harness from the VSS.
Check for continuity and proper voltage output while the vehicle is in motion.
Replace the VSS if it fails to provide accurate readings.

5. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse related to the cruise control system, referring to the owner’s manual.
Inspect the fuse for continuity and replace it if blown.
