Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Disconnect the negative battery terminal to ensure safety.

2. Inspect Cruise Control Switch

Remove the steering wheel cover using a socket set.
Disconnect the cruise control switch connector.
Inspect the switch for any visible damage.
If damaged, replace with a new cruise control switch.

3. Check Fuses

Locate the fuse box (refer to the owner's manual for exact location).
Identify the fuse associated with the cruise control system.
Use a multimeter to check for continuity; replace any blown fuses with the same amperage rating.

4. Inspect Brake Pedal Position Switch

Locate the brake pedal position switch, typically mounted near the top of the brake pedal.
Check for proper operation by pressing the brake pedal; the switch should click.
If faulty, replace the brake pedal position switch.

5. Test Vehicle Speed Sensor

Locate the vehicle speed sensor, typically mounted on the transmission.
Disconnect the sensor and use a multimeter to measure resistance; refer to service manual for specifications.
If out of range, replace the vehicle speed sensor.

6. Examine Throttle Cable and Electronic Throttle Body

Inspect the throttle cable for signs of wear or binding; lubricate or replace as necessary.
If equipped with an electronic throttle body, check for error codes and clean if necessary using throttle body cleaner.
