Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers
Torque wrench

2. Inspect Fuses

Locate the fuse box (refer to the owner's manual for the exact location).
Use a fuse puller or needle-nose pliers to remove each fuse related to the cruise control system.
Inspect each fuse for continuity; replace any blown fuses with the correct amperage.

3. Check Brake Pedal Switch

Locate the brake pedal switch (usually found above the pedal).
Disconnect the electrical connector from the brake pedal switch.
Use a multimeter to test the switch for continuity when pressed; replace the switch if it fails to show continuity.

4. Inspect Steering Wheel Controls

Carefully remove the airbag module from the steering wheel (follow manufacturer's safety procedures).
Inspect the electrical connectors for the cruise control buttons.
Verify no damaged wires or poor connections; repair or replace connectors as necessary.

5. Test Speed Sensors

Locate the vehicle speed sensors (typically near the transmission).
Use a multimeter to check the output voltage while the vehicle is moving.
If the speed sensor is not providing the correct voltage, replace it with a new sensor.
