Lexus, unlike traditional vehicles, has various adaptive features that improve driving safety, convenience, and comfort. Adaptive cruise control is one of these advanced technology systems that helps to achieve an excellent driving experience.
Adaptive cruise control (ACC) works like the regular cruise control system by keeping a safe distance from the vehicle in front of your car. However, the ACC system does even more by adjusting your car’s speed to match traffic conditions. What do you do if this system malfunctions and fails? This guide will help provide some answers.
What Causes Adaptive Cruise Control Malfunctions in your Lexus?
Let us first understand the intricacies of the Adaptive Cruise Control (ACC) system and its functions. The ACC system is a driver assistance system that helps to improve safety and driving conditions. As discussed above, the ACC helps to keep your car at a safe distance from other vehicles on the road to prevent accidents. However, this is not all that it does.
The ACC system detects and monitors road conditions, it then adjusts your car’s speed to match the conditions. For example, if the vehicle before you suddenly stops or reduces its speed, the ACC system detects this and also reduces your car’s speed to prevent collision.
For this system to function adequately, it relies on various components such as sensors and cameras. If any of these components fail or malfunction, it could affect the function of the adaptive cruise control system.
Here are some factors that influence ACC system failures in a car:
1. Faulty Radar Sensors
The importance of radar sensors and cameras cannot be overemphasized when it comes to the adaptive cruise control system. The sensors and cameras allow the system to detect obstacles and other surrounding vehicles so the ACC system can adjust the car’s movement to prevent clashes.
2. Visibility Problems
Another common cause of failure in the adaptive cruise control system for most vehicles is a visibility problem. The sensor radar and camera are typically located behind the windshield and if anything clouds the windshield, then there can be problems with visibility. Factors such as a dirty or stained windshield, fog, heavy rain, and poor lighting can cause ACC problems.
Symptoms of a Faulty Adaptive Cruise Control in Your Lexus
Malfunctions in your car’s adaptive cruise control system can show up in various ways and ignoring these signs can put your car at a safety risk. Here are some of the signs you should look out for.
Warning Lights
The ACC system, like several other systems, has warning lights to help indicate when there is a problem with its system. This light usually illuminates on a car’s dashboard when the sensors are faulty or not properly aligned.
Speed Control Issues
If your car fails to maintain a steady speed or does not match the speed of surrounding vehicles when the ACC system is activated, then it means there is a problem with the cruise control system. If you notice that your car does not stop or slow down when the car before it slows down, it means there is a system issue.
Unresponsive Braking
The braking system works along with the ACC system to prevent collision with traffic. However, if the adaptive cruise control system fails or malfunctions, its sensors will fail to communicate with the braking system and this usually leads to braking or acceleration issues.
Other signs include;
- Error message on the dashboard or infotainment system.
- Difficulty in maintaining a safe following distance.
