Solution

1. Preparation

Gather tools including an OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a level surface with the engine off and the keys removed from the ignition.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Record any error codes related to the cruise control system for further analysis.

3. Inspect the Cruise Control Switch

Remove the steering wheel cover using a socket set and screwdrivers.
Check the cruise control switch for any visible damage or loose connections.
If damaged, replace the switch with a new one.

4. Check Brake Pedal Switch

Locate the brake pedal switch under the dashboard.
Use a multimeter to test the switch for continuity when the pedal is pressed.
If the switch is faulty, replace it with a new component.

5. Inspect Fuses

Open the fuse box and locate the fuse related to the cruise control system.
Remove the fuse and inspect it for continuity; replace if blown.
Refer to the vehicle’s manual for the specific fuse location and rating.

6. Examine Wiring and Connectors

Visually inspect wiring harnesses and connectors leading to the cruise control system.
Look for frayed wires or corroded connectors; repair or replace as necessary.

7. Test Vehicle Speed Sensor

Locate the vehicle speed sensor (usually near the transmission).
Use a multimeter to test the sensor output for proper voltage signals.
If the sensor is malfunctioning, replace it with a new unit.
