Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect Brake Pedal Switch

Locate the brake pedal switch, which is usually mounted above the brake pedal.
Remove any covers if necessary to access the switch.
Disconnect the wiring harness from the brake pedal switch.
Test the switch for continuity using a multimeter. Replace the switch if it does not function correctly.
Reconnect the wiring harness and ensure the switch is properly aligned and installed.

3. Check Cruise Control Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the cruise control fuse.
Inspect the fuse for continuity. Replace it with a new fuse of the same amperage if it is blown.
Reinstall the fuse and close the fuse box.

4. Inspect Steering Wheel Controls

Remove the airbag module or steering wheel cover carefully following the service manual.
Check the connections and wiring for the cruise control switches for any damage or disconnection.
Test the cruise control switches with a multimeter to ensure they are functioning. Replace them if defective.
Reassemble the steering wheel and airbag module, ensuring all connections are secure.

5. Verify Throttle Body and Speed Sensor

Remove the air intake duct to access the throttle body.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
Inspect the throttle position sensor for proper operation and wiring integrity.
Check the vehicle speed sensor located on the transmission. Inspect wiring and connectors; replace if faulty.
