Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Cruise Control Fuse

Locate the fuse box (typically found under the dashboard or in the engine bay).
Remove the cruise control fuse and inspect it for damage.
If blown, replace it with a fuse of the same amperage (usually 10A or 15A).
Reconnect the battery terminal.

3. Inspect Brake Pedal Switch

Locate the brake pedal switch, typically mounted on the pedal assembly.
Check the switch operation by pressing the brake pedal; it should click.
If faulty, disconnect the switch and replace it with a new one, ensuring proper alignment and connection.

4. Examine Cruise Control Stalk/Buttons

Remove the steering column cover to access the cruise control stalk.
Inspect for any visible damage or wear.
If necessary, replace the cruise control switch assembly by disconnecting the wiring harness and securing the new unit in place.

5. Test Throttle Position Sensor

Use a multimeter to test the throttle position sensor for proper resistance values.
If out of specification, replace the throttle position sensor by disconnecting the harness and removing the mounting screws.

6. Verify Vehicle Speed Sensor

Locate the vehicle speed sensor (often near the transmission).
Check wiring and connections for damage.
If faulty, replace the sensor by removing it from its housing and installing the new sensor securely.
