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 prevent any electrical shorts.

2. Inspect Fuses

Locate the fuse box, usually found under the dashboard or in the engine bay.
Use a fuse puller to remove the cruise control fuse.
Inspect the fuse for any signs of damage; replace with an equivalent fuse if blown.

3. Check Brake Pedal Switch

Locate the brake pedal switch, typically mounted near the brake pedal arm.
Disconnect the electrical connector and use a multimeter to test the switch for continuity.
If the switch is faulty, replace it with a new one, ensuring it properly engages when the brake pedal is pressed.

4. Verify Cruise Control Module

Locate the cruise control module, which may be found under the dashboard or in the engine compartment.
Inspect the module for any visible damage or loose connections.
Reconnect any loose wires and ensure all connections are secure. Replace the module if necessary.

5. Test Vehicle Speed Sensor

Locate the vehicle speed sensor, usually on the transmission.
Disconnect the sensor and check its resistance with a multimeter; refer to the service manual for specific resistance values.
If the sensor is faulty, replace it with an OEM part.

6. Check Cruise Control Switch

Remove the steering wheel cover to access the cruise control switch.
Inspect the switch for any physical damage or wear.
Use a multimeter to test for continuity. If defective, replace the switch.
