Solution

1. Preparation

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

2. Inspect the Fuse

Locate the fuse box and identify the cruise control fuse.
Remove the fuse and check for continuity using a multimeter.
Replace the fuse if blown and reconnect it.

3. Check the Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Disconnect the wiring harness from the switch.
Test for continuity with a multimeter while pressing the brake pedal. If no continuity, replace the switch.

4. Test the Throttle Position Sensor

Locate the TPS on the throttle body.
Disconnect the TPS connector.
Using a multimeter, check the resistance and ensure it falls within the manufacturer’s specifications. Replace if out of range.

5. Inspect the Cruise Control Actuator

Locate the cruise control actuator in the engine bay.
Check for any loose connections or damaged wires.
Ensure that the actuator moves freely and is not obstructed. Replace if damaged.

6. Reconnect and Test

Reconnect all components, including the battery terminal.
Start the vehicle and test the cruise control system to ensure it is functioning correctly.
