Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Inspect the Brake Pedal Switch

Locate the brake pedal switch, typically mounted above the brake pedal.
Remove any panels obstructing access.
Disconnect the switch connector and use a multimeter to test continuity while pressing the brake pedal.
- If there is no continuity, replace the brake pedal switch.
- If continuity is present, reconnect the switch.

3. Check Steering Wheel Controls

Remove the steering wheel cover following manufacturer instructions.
Inspect the cruise control buttons for proper connection to the wiring harness.
If damaged, replace the steering wheel control assembly.

4. Test Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Disconnect the electrical connector and use a multimeter to measure voltage output.
- Compare readings to manufacturer specifications.
- If readings are out of range, replace the TPS.

5. Inspect Vehicle Speed Sensor

Locate the speed sensor, usually found near the transmission.
Remove the sensor and inspect for dirt or damage.
Test the sensor output using a multimeter while the vehicle is in motion.
- If it fails to provide a consistent signal, replace the speed sensor.

6. Verify Cruise Control Module

Inspect the cruise control module for any signs of damage or corrosion.
Ensure all wiring connections are secure and free from fraying.
If the module is faulty, replace it with a new unit.
