Learn to Fix Cruise Control.
While most drivers do not use it on a daily basis, a vehicle’s cruise control system comes in extremely handy when drivers are on the open highway. And because it is so rarely used, a vehicle with cruise control problems can be difficult to diagnose. Moreover, when it comes to knowing how to fix cruise control, Gilbert AZ drivers agree that it is most certainly not an easy task. To begin with, most drivers do not even understand how a cruise control system works, much less how to fix cruise control issues. This article will provide a brief overview of the cruise control system, and the various components that could potentially wear out and give reason to fix a vehicle’s cruise control system. Drivers from Gilbert, AZ and the world around can benefit from this discussion.
How does cruise control work?
As most people know, a cruise control system works to maintain a vehicle’s speed. What many people do not realize is that cruise control operates much as if a driver was adjusting the throttle manually. Instead of opening the throttle with the gas pedal, however, a cruise control uses an actuator with a cable connecting it to the throttle. When the throttle opens up, more air goes into the vehicle’s engine, causing the car or truck to accelerate. The majority of vehicles use a vacuum-like device to power the actuator. As you can see, there are many components in a cruise control system. If any one of these pieces wears out, it could give reason to fix cruise control.
What is a cruise control system comprised of?
The following describes all of the components in a cruise control system, and provides a description of what each component does:
1. The Actuator: This component is powered by the cruise control module, and controls the throttle so that the appropriate speed may be maintained.
2. The Brake Switch: This component is mounted on the brake pedal to stop the cruise control system if the pedal is so much as tapped. Once the vehicle’s cruise control is disengaged with this switch, the speed is saved in the system’s memory so that it can be reset.
3. The Cruise Control Module: This component stores the speed that the driver sets, compares it to the actual speed of the vehicle, and then sends messages to the actuator until the set speed matches the actual speed.
4. The Speed Sensor: This component is used to send the actual speed of the vehicle to the cruise control module so that the cruise control module knows whether to tell the vehicle to speed up or slow down.
5. The Clutch Switch: This component is only present on vehicles with a manual transmission, and operates like a brake switch to disengage the cruise control if the clutch is pressed.
6. The Throttle Linkage: This is the connection between the throttle and the actuator.
Each of these components has a unique purpose, and they all must work in conjunction for the cruise control system to function. The average driver will have difficulty diagnosing a problem with the cruise control system, due to its complexity. As such, most people call on professionals to fix cruise control.
