Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Cruise Control Switch

Tools Required: Screwdriver set, trim removal tool
Remove the steering wheel cover by using a trim removal tool to gently pry it off.
Unscrew and remove the cruise control switch from the steering wheel.
Inspect the switch for any signs of damage; if damaged, replace with a new switch.
Reinstall the cruise control switch and reassemble the steering wheel cover.

3. Check and Replace Brake Pedal Position Switch

Tools Required: Socket set
Locate the brake pedal position switch, typically mounted on the brake pedal assembly.
Disconnect the wiring harness from the switch.
Remove the switch by unscrewing it from its mounting.
Install a new brake pedal position switch and reconnect the wiring harness.

4. Inspect and Replace Fuses

Tools Required: Fuse puller or pliers
Locate the fuse box under the dashboard or hood.
Identify the fuse associated with the cruise control system (refer to the owner's manual for exact location).
Check the fuse for continuity; if blown, replace it with a fuse of the same amperage.

5. Test Throttle Position Sensor

Tools Required: Multimeter
Locate the throttle position sensor on the throttle body.
Disconnect the sensor's electrical connector.
Set the multimeter to measure resistance and check the sensor's readings against the specifications in the service manual.
If out of spec, replace the throttle position sensor.
