Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the vehicle battery to avoid electrical shorts while working on the system.

2. Inspect and Replace Cruise Control Switch

Remove the airbag cover from the steering wheel using a socket set.
Disconnect the electrical connector from the cruise control switch.
Test the switch for continuity using a multimeter. Replace if faulty.
Reconnect the switch and reassemble the steering wheel components.
Reconnect the battery.

3. Check and Replace Brake Pedal Switch

Locate the brake pedal switch above the brake pedal.
Disconnect the electrical connector and remove the switch from its mounting.
Test the switch with a multimeter for continuity when the pedal is pressed. Replace if defective.
Install the new switch and reconnect the electrical connector.

4. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse related to the cruise control system.
Remove the fuse and visually inspect for a break. Replace with the same amperage fuse if blown.

5. Inspect Throttle Body and Sensor

Remove any air intake ducting to access the throttle body.
Check for carbon build-up and clean if necessary using throttle body cleaner.
Inspect the accelerator pedal position sensor wiring for damage. Replace if required.
Reassemble all components and reconnect any removed ducting.
