Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set.
Disconnect the vehicle's battery to ensure safety while working on the electrical components.

2. Inspect the Brake Pedal Switch

Locate the brake pedal switch, typically mounted on the brake pedal assembly.
Remove any necessary covers to access the switch.
Use a multimeter to check for continuity when the brake pedal is pressed. If there is no continuity, the switch needs replacing.
If necessary, replace the brake pedal switch by disconnecting the wiring harness, removing the switch, and installing the new one. Reconnect the wiring harness.

3. Check the Vehicle Speed Sensor

Locate the vehicle speed sensor, usually found on the transmission.
Disconnect the sensor's electrical connector.
Use a multimeter to measure the output voltage while the vehicle is moving. If the sensor is faulty, it should be replaced.
Remove the old speed sensor and install a new one, ensuring it is properly secured and reconnected.

4. Inspect Wiring and Connections

Visually inspect all wiring and connections related to the cruise control system, including those at the cruise control module and the steering wheel buttons.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring as necessary.

5. Test the Cruise Control Stalk/Button

Remove the steering column covers to access the cruise control stalk or buttons.
Inspect for any physical damage or wear.
Conduct a continuity test with a multimeter to ensure that the stalk/button is functioning correctly.
Replace the stalk/button if any issues are detected.
