Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dash or in the engine compartment).
Remove the cover and identify the cruise control fuse using the diagram on the cover.
Use a multimeter to check continuity; if the fuse is blown, replace it with a fuse of the same amperage.

3. Check Brake Pedal Switch

Locate the brake pedal switch mounted above the brake pedal.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity with the pedal pressed and released.
If faulty, remove the switch by unscrewing it from its mount and replace it with a new part.

4. Inspect Cruise Control Module

Locate the cruise control module (usually near the steering column).
Disconnect the power connector and inspect for corrosion or damage.
If damaged, remove the module by unscrewing it from its mounting bracket and install a new module.

5. Verify Throttle Position Sensor

Locate the throttle position sensor (TPS) on the throttle body.
Check the sensor’s connector for any loose wires or damage.
Use a multimeter to check the TPS voltage; it should vary smoothly as the throttle is opened and closed.
Replace the TPS if it fails to provide the correct voltage readings.

6. Reassemble and Reconnect

Reconnect all connectors and ensure all components are securely mounted.
Reconnect the battery.
Test the cruise control functionality before closing up the fuse box or any covers.
