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 terminal to prevent electrical shorts.

2. Inspect Cruise Control Switch

Remove the airbag module from the steering wheel using a socket set (usually Torx or socket screws).
Disconnect the wiring harness for the cruise control switch.
Visually inspect the switch for any visible damage.
If damaged, replace the cruise control switch with a new part.

3. Check Brake Pedal Switch

Locate the brake pedal switch, typically mounted above the brake pedal.
Disconnect the wiring connector and use a multimeter to test continuity when the brake pedal is pressed.
Replace the brake pedal switch if it fails the continuity test.

4. Verify Vehicle Speed Sensor

Locate the vehicle speed sensor, usually found on the transmission or differential.
Disconnect the sensor's wiring harness and test the sensor with a multimeter for proper resistance values according to manufacturer specifications.
Replace the vehicle speed sensor if it is faulty.

5. Inspect Cruise Control Module and Wiring

Locate the cruise control module, usually found near the engine compartment.
Check all wiring connections for corrosion, loose connections, or damage.
Repair or replace any damaged wiring or connectors.
