Generally, millennials prefer high-end cars like BMW for their advanced features which makes driving these high-end cars a real pleasure. One such advanced system is the active cruise control which plays a great role in the smooth running and better performance of your high-end car.

However, like other mechanical parts in your BMW, the active cruise control can also encounter issues. Here in this article, we will discuss the important parts that you need to inspect whenever the active cruise control stops working shared with us by the experts in Dallas, TX.

• Brake Pedal Switch
• Speed Sensor
• Fuse Box
• Vacuum Actuator
• Electrical Components

Brake Pedal Switch

One of the first things that you need to check whenever the active cruise control in your BMW fails is the brake pedal of your car. The cruise control is an automated system that manages the speed of the car without the need for any human intervention.

The activation and deactivation of the cruise control is dependent on the brakes of your car and the moment you press the brake pedal the cruise control deactivates as it is a safety-related feature in your vehicle. Most of the time it is observed that the cruise control functions erratically when the brake pedal switch malfunctions.

The erroneous signals being transferred from the brake pedal switch to the onboard computers make the cruise control believe that the driver is applying the brakes and that is when it stops functioning. If the cruise control in your high-end car frequently deactivates when driving, then you need to have a look at the brake pedal switch.

Now, identifying issues with the functioning of the brake pedal switch is very challenging for BMW drivers & that is why they need to get in touch with a qualified mechanic who can inspect the component and replace the brake pedal switch if it is faulty.

Speed Sensor

There are numerous sensors in your high-end vehicle that keep a tab on the functioning of the vital components and the speed sensor is one such sensor. Generally, drivers believe that the speed sensors only keep a tab on the speed of their vehicle, however, the speed sensors also regulate the fuel flow & operation of the active cruise control.

For the smooth functioning of the active cruise control your BMW needs to be above a certain speed threshold and then only the cruise control can be activated. The speed sensor plays a critical role over here by transmitting the required signal to the cruise control.

However, when the speed sensor is itself faulty then the correct information related to the speed of your vehicle won’t be transferred to the cruise control and it won’t get activated. No matter what is the speed of the vehicle, the cruise control won’t be able to determine the correct speed and will stop working.

Fuse Box

The active cruise control system in your vehicle is controlled electronically and there is a fuse that monitors the flow of electrical signal to the cruise control. The fuse is responsible for cutting off the connection in case there is a flow of heavy electrical current to the system in order to protect the other wires from damage.

Now, if you are having a blown fuse in your car then the active cruise control is not going to work because it won’t be receiving any electrical input because of a break in the connection. The fuse box in your car contains all the fuse and you have to refer to your owner’s manual to determine the correct fuse connected to the cruise control.

Vacuum Actuator

The active cruise control in your luxury car depends on the vacuum actuator & its connections for its smooth functioning. There are cables present in the vacuum actuator that connect the cruise control to the throttle response for its optimal functioning.

Most of the time it is seen that if there is an issue with the functioning of the vacuum actuator or the cable connecting the cruise control with the throttle is loose then the active cruise control won’t function.

Electrical Components

The electrical components connected to the active cruise control also play a critical role in its smooth functioning. Like other cars, your BMW is also prone to electrical problems and this can also affect the working of the active cruise control system in your car.

You need to have your electrical connections inspected by a certified mechanic so that the source of the problem can be identified and remedial measures initiated in time.
