Cruise control is a useful technology for drivers, as it is designed to solve the problem of driver fatigue during frequent long-distance trips. However, it is also prone to breakage. In most cases, cruise control failure is due to a faulty brake or clutch pedal sensor. However, there are other problems that the driver should be aware of. If you are worried that you will have to use a scrap car value calculator in 2022 due to numerous car breakdowns, then this article is for you. Here are some tips for caring for such an important element of a car as cruise control.
There are five main reasons why cruise control does not work:
You need to check the cruise control for performance at speed. In most cars, the activation of the system is blocked when the speed does not exceed 24,85 miles per hour.
Most often, passive cruise control does not work due to problems with contacts and limit switches. The ECU will not allow turning on the cruise control system even if it does not receive a signal from one of the sensors due to broken wiring, oxidation of the terminals, etc. Among the main causes of breakdowns of passive cruise control:
Often due to problems with cruise control, automatic speed control is not available for the following reasons:
Adaptive cruise control (ACC) is a more advanced system, closer to autopilot. She knows how not only to maintain a given speed but also to adapt to the surrounding traffic, focusing on the readings of the distance sensor (radar, lidar) installed in the front of the car.
Modern ACC systems can determine the position of the steering wheel, wheels, and track road markings. This system helps the driver to maintain control with the help of the EPS to keep the car in the lane when the road bends.
The main ACC malfunctions are:
A speed limiter is a system that prevents the driver from exceeding the speed set by the user in manual control mode. Depending on the model, the limiter may be part of a single system with cruise control or be independent. Drivers are faced with the fact that cruise control does not hold the speed limit. Also, cruise control may not work even if the speed limiter works.
Typical malfunctions of a speed limiter:
In certain models, cruise control often fails due to design flaws – unreliable or poorly installed sensors, weak contacts, etc. The problem is also typical for cars with high mileage and cars operated in difficult conditions. In such cases, the most vulnerable parts should be checked first.
Let’s look at the weak points of cruise control in some popular car models.
Most often, a cruise malfunction is detected on the highway when there is no diagnostic scanner or multimeter at hand. If the cruise control suddenly stops working, first of all, it is worth checking the main reasons for the failure:
Cruise control is an important technology for drivers who spend a lot of time behind the wheel. It is important to monitor the performance of cruise control and related components. If you have a car with broken cruise control, transmission, or engine, you can sell it quickly with JunkCarsUs. The company buys used, non-running cars, as well as cars after accidents.
