Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual for location).
Remove the fuse for the cruise control system using a fuse puller.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reinstall the fuse and reconnect the battery.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Ensure that the switch is properly aligned and functioning; it should click when the pedal is pressed.
If faulty, disconnect the switch and replace it with a new one.
Reconnect the battery and test the cruise control.

4. Test Vehicle Speed Sensor

Locate the vehicle speed sensor, typically found on the transmission.
Disconnect the electrical connector and check for continuity using a multimeter.
If the sensor is faulty, replace it with a new sensor.
Reconnect the wiring and test the cruise control operation.

5. Reconnect and Test

Reconnect the battery.
Start the vehicle and test the cruise control functionality on a safe, open road to ensure proper operation.
