Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the cruise control fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity with a multimeter.
- If blown, replace it with a new fuse of the same amperage.

3. Check Brake Pedal Switch

Locate the brake pedal switch, usually above the brake pedal arm.
Ensure the switch is properly aligned and functioning.
- If faulty, disconnect the wiring harness and replace the switch with a new unit.

4. Inspect Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and test the sensor's resistance with a multimeter.
- If out of range, replace the throttle position sensor.

5. Examine Cruise Control Actuator

Locate the cruise control actuator, typically mounted near the throttle body.
Inspect the actuator for any visible damage or disconnections.
If damaged, remove the actuator by unscrewing it from its mount and replacing it with a new unit.

6. Test Steering Wheel Controls

Remove the airbag and steering wheel cover as per manufacturer guidelines.
Inspect the wiring and connections for the cruise control buttons.
- If damaged, repair or replace the wiring harness or controls.
