Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Cruise Control Switch

Remove the steering wheel cover (if necessary) using a socket set.
Disconnect the cruise control switch connector.
Inspect the switch for damage and continuity with a multimeter.
If faulty, replace with a new cruise control switch. Reconnect the connector.

3. Test and Replace Brake Pedal Switch

Locate the brake pedal switch, usually situated above the brake pedal.
Check the switch operation by pressing the brake pedal; it should engage and disengage smoothly.
If defective, remove the switch by turning it counterclockwise and replace it with a new component.

4. Inspect Vehicle Speed Sensor (if necessary)

Locate the vehicle speed sensor, typically on the transmission.
Disconnect the sensor and check for any visible damage.
Use a multimeter to test the sensor's output; replace if it does not meet specifications.

5. Inspect Fuses

Open the fuse box and locate the fuse related to the cruise control system, usually labeled in the lid.
Remove the fuse and inspect for continuity. Replace if blown.

6. Reconnect Battery and Test System

Reconnect the battery.
Start the vehicle and test the cruise control system to ensure it functions properly.
