What is Cruise Control in a Vehicle?

When you are driving on an open road for a long time, it is very tiring to keep pressing the accelerator pedal.

The cruise control system is a technology that helps drivers maintain a steady speed. It uses the vehicle’s speed sensors to monitor the speed of the car and activates the brakes when it detects the driver trying to accelerate too quickly. It does this by maintaining a certain distance between you and the car in front of you.

 

With the cruise control system, you can speed up or slow down while you are driving. You can also set the vehicle to automatically accelerate or decelerate when you reach a certain speed.  Instead of pressing the accelerator pedal, the throttle is controlled by an actuator. And it allows your car to continue to cruise at the same speed.

 

The features that allow you to use cruise control are very useful to help relieve the feelings of fatigue that you may feel while driving a long distance. This system is based on the way human drivers drive.

What to Do if Cruise Control is Not Working

If you are driving your vehicle and it does not seem to be accelerating or decelerating, the cruise control system may be not working. Here are some of the things that you can do:

 

1) Look for a blown fuse

The first thing you should do is to check the fuse that is connected to the cruise control system. This is because a blown fuse is one of the most common reasons as to why the cruise control system in a vehicle can stop working.

 

It can be found under the hood of your car or on the side of it. You can remove the fuse from its place and try testing it with a voltmeter. If it checks good, then you can move on to the next troubleshooting objective. If not, though, you will need to replace it with a new one. Check the owner’s manual for the fuse that corresponds to your car’s specific cruise control technology.

 

2) Look for a faulty brake pedal switch

If the fuse is not the problem, then you will need to check for a faulty brake pedal switch. The brake pedal switch is a small metal plate that sits between the brake pedal and the throttle. It’s connected to your cruise control system and it senses if you are pressing on the brake pedal or not.

 

If it is damaged, then your cruise control system will stop working until you replace it. If you notice that there is no power coming from your cruise control system while driving, then this may be one of the causes of this problem.

 

Because the cruise control is wired into the brake pedal switch, any fault or defect in the wiring may cause it to stop working. When the brake pedal switch malfunctions, the car thinks that the brakes are engaged and therefore it will turn off automatically. Additionally, your car’s brake light might be stuck on, leaving other drivers in the same road as yours confused.

 

If you have a faulty brake pedal switch, then you will need to replace it.

 

3) Look for a damaged speed sensor

If the brake pedal switch is not the problem, then you will need to check for a damaged speed sensor. The speed sensor is located in front of your engine and it monitors your vehicle’s speed. It sends this information to the cruise control system and it activates the brakes when you try to accelerate too quickly.

 

If a sensor stops working, the cruise control will subsequently malfunction, and the speedometer may start to act strangely. You may end up getting inaccurate readings from the sensor, which can be very dangerous

 

When there is a problem with a speed sensor, you will have either an ABS warning light or a check engine light on the dashboard. Check if there are any signs of damage on your speed sensor. If so, then you will need to replace it with a new one.

 

4) Check for faulty wirings or connectors

If you have replaced the brake pedal switch and speed sensor, but the cruise control still does not work, then you will need to check for faulty wirings or connectors. This is a common problem with most cars. There are many electrical parts that are in close proximity to each other, which can lead to short circuits.

 

Check your wiring diagram to see if there is any faulty wiring that needs to be repaired or replaced. If so, then you will need to repair it by replacing damaged wires or fixing a faulty connector. Check the owner’s manual for the exact location of each wire and make sure that it matches your car’s specific wiring diagram.

 

5) Check the cruise control buttons and levers

If the cruise control is not working, then you will need to check the buttons and levers on your dashboard. There are many buttons and levers that are located in front of your steering wheel.

 

Some of them are for controlling your car’s functions such as the windows, windshield wipers, seat heaters, and more. Some other ones are for controlling your cruise control system such as the button or the button that allows you to turn off the cruise control.

 

Make sure that these buttons and levers work correctly, and that neither of them are loose or lodged somewhere. When these do not work properly, it can be very dangerous for you on the road.
