Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Address Error Codes

If error codes are present, research them to determine the specific issue and address it accordingly.

3. Cruise Control Switch Replacement

Remove the steering wheel cover:
- Disconnect the battery.
- Use a socket set to remove screws securing the cover.
- Gently pry off the cover.
Replace the cruise control switch:
- Disconnect the electrical connector from the old switch.
- Install the new switch and reconnect the electrical connector.
Reassemble the steering wheel cover:
- Secure the cover back in place and reattach screws.

4. Brake Switch Inspection/Replacement

Locate the brake pedal switch:
- Inspect the switch for proper alignment and function.
Adjust or replace the switch if necessary:
- If misaligned, adjust its position to ensure proper operation.
- If faulty, remove the old switch and install a new one.

5. Fuse Inspection

Check the fuse box:
- Locate the fuse related to the cruise control system (refer to the owner's manual for the exact location).
- Replace any blown fuses with the correct amperage.

6. Throttle Position Sensor Testing

Test the throttle position sensor:
- Disconnect the sensor and connect a multimeter to the terminals.
- Measure voltage while manually moving the throttle; it should show a smooth transition without dead spots.
Replace the sensor if it is faulty.
