Cruise Control: Exploring its Benefits, Common Issues and Expert Repair Insights

In today’s fast-paced world, long drives and road trips have become an integral part of our lives. To make these journeys smoother and more enjoyable, modern vehicles are equipped with a sophisticated feature known as cruise control. Bashi’s Auto Electrical specialises in cruise control repairs and maintenance. In this guide we will cover the functionalities and advantages of cruise control, common reasons for its failure and how Bashi’s Auto Electrical expertly diagnoses and repairs these issues.

How Cruise Control Functions

Cruise control, also referred to as speed control or autopilot, is an automotive feature that allows drivers to maintain a constant speed without applying the accelerator pedal. Once the desired speed is set, the vehicle’s cruise control system takes over, adjusting the throttle and ensuring the car maintains a steady pace. This feature is particularly useful during long drives on highways, as it reduces driver fatigue and provides a more relaxed driving experience.

Cruise control operates through a combination of electronic components, including sensors, actuators, and a control module. The driver activates the cruise control system using buttons or a lever on the steering wheel. The system then utilises data from vehicle speed sensors to determine the current speed. By modulating the throttle and adjusting the engine’s output, the cruise control maintains the selected speed until the driver intervenes by applying the brakes or deactivating the feature.

Common Reasons for Cruise Control Failure

Despite the convenience of cruise control, it can experience issues that lead to malfunctioning. At Bashi’s Auto Electrical, our experienced technicians have encountered several common reasons for cruise control failure:

Electrical Issues:

  • Blown Fuses and Circuit Problems: Faulty fuses or damaged circuits can disrupt the flow of electricity to the cruise control system, causing it to fail.
  • Faulty Control Module: The control module is the brain of the cruise control system. If it malfunctions, the entire system can be affected.
  • Damaged Wiring or Connectors: Corroded or broken wiring and connectors can interrupt the communication between various components, leading to failure.

Mechanical Problems:

  • Throttle Linkage or Cable Malfunctions: Issues with the throttle linkage or cable can prevent the system from adjusting the throttle properly.
  • Brake Light Switch Issues: A faulty brake light switch may not signal the cruise control to disengage when the brakes are applied, posing a safety risk.
  • Vehicle Speed Sensor Problems: Malfunctioning speed sensors can result in inaccurate speed readings, leading to erratic cruise control behaviour.

Sensor and Actuator Failures:

  • Accelerator Pedal Position Sensor: If the accelerator pedal position sensor fails, the system may not respond to the driver’s input correctly.
  • Brake Pedal Position Sensor: Malfunctions in the brake pedal position sensor can prevent the cruise control from disengaging when the brakes are applied.
  • Clutch Position Sensor (for manual vehicles): In manual transmission vehicles, a faulty clutch position sensor can lead to cruise control issues.

The Impact of Cruise Control on the Engine

A common misconception is that using cruise control adversely affects the engine’s performance and fuel efficiency. However, when properly utilised, cruise control can have a positive impact on the engine. By maintaining a steady speed, cruise control reduces unnecessary acceleration and deceleration, leading to improved fuel efficiency and reduced engine strain during long journeys.

Frequently Asked Questions

Q: What would cause the cruise control to stop working?

A: Cruise control may stop working due to blown fuses, circuit problems, a faulty control module, damaged wiring, or connector issues.

Q: How do you diagnose a bad cruise control?

A: Diagnosing a faulty cruise control involves a comprehensive inspection of the system, checking for electrical, mechanical, sensor, or actuator issues.

Q: Does cruise control affect the engine?

A: No, when properly used, cruise control can actually benefit the engine by maintaining a constant speed and reducing unnecessary strain.
