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 cable to prevent electrical shock.

2. Inspect and Replace the Cruise Control Switch

Remove the airbag module from the steering wheel (follow manufacturer's guidelines for safe removal).
Disconnect the electrical connector from the cruise control switch.
Inspect the switch for continuity using a multimeter. If faulty, replace it with a new component.
Reconnect the electrical connector and reassemble the airbag module.

3. Check and Replace Brake Pedal Switch

Locate the brake pedal switch, usually mounted above the brake pedal.
Disconnect the electrical connector from the switch.
Test the switch for continuity. If the switch is defective, remove it from the mounting bracket and install a new switch.
Reconnect the electrical connector and ensure proper alignment with the brake pedal.

4. Inspect and Replace Fuses

Locate the fuse box (refer to the owner’s manual for location).
Identify the cruise control fuse and visually inspect it for damage.
If blown, replace it with a fuse of the same amperage rating.

5. Throttle Position Sensor Check

Locate the throttle body and disconnect the throttle position sensor connector.
Use a multimeter to check the sensor’s voltage output while manually moving the throttle.
If the readings are outside the manufacturer’s specifications, replace the throttle position sensor.
