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 and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box and identify the cruise control fuse according to the owner’s manual.
Remove the fuse and inspect it for continuity. If blown, replace it with a fuse of the same amperage.

3. Check Brake Pedal Switch

Tools Required: Multimeter.
Locate the brake pedal switch, typically found near the top of the brake pedal.
Disconnect the switch connector and use the multimeter to test for continuity. If the switch is faulty, replace it with a new one.

4. Test Cruise Control Buttons

Tools Required: Multimeter.
Remove the steering wheel cover to access the cruise control buttons.
Disconnect the cruise control wiring harness and use a multimeter to test the buttons for continuity when pressed. Replace any faulty buttons or the entire switch assembly.

5. Verify Throttle Position Sensor

Tools Required: Multimeter.
Locate the throttle position sensor and disconnect it.
Use the multimeter to check the sensor’s voltage output as per manufacturer specifications. If out of range, replace the throttle position sensor.
