Your Volvo has exceptional technological features that help to improve the quality of rides and enhance safety. One such feature is the Adaptive Cruise Control (ACC) which helps to adjust your car’s speed based on road conditions. However, the ACC is not 100% perfect as it could develop some issues along the way.
The best way to address any issue is to first understand why it is happening. We have provided this guide to explain the common causes of adaptive cruise control failure in a car and how to deal with the problem.
Volvo’s Adaptive Cruise Control System and Reasons for its Failures
When your Volvo has the adaptive cruise control feature, it can automatically adjust the speed of your car to ensure you don’t have a collision with the car in front of you. If you are using cruise control, it can also detect if the vehicle in front of you is slowing, and it will adjust your Volvo’s speed as well. This helps to prevent accidents and collisions along with your cruise control features.
Unfortunately, in some cases, this cruise control system may fail to work, and here are some common reasons why this could happen.
- Faulty Sensors: Usually, the ACC relies on radar sensors and cameras at the front of your vehicle to help detect obstacles in your front and also determine the speed or movement of other vehicles you are following. If these sensors get faulty or the camera is blocked by dirt or other contaminants, the ACC may fail to perform its functions.
- Bad Weather Condition: Visibility is an important factor when it comes to the use of adaptive cruise control when driving. Poor visibility, which is usually caused by poor lighting or bad weather conditions can affect the ACC’s function. For example, when it is raining heavily, your Volvo’s windshield can fog up and since the sensor radar and camera are usually behind the windshield, they may be unable to function adequately, leading to a failure.
- Software Problems: Another common reason why your Volvo’s adaptive cruise control could be failing is when your car has software issues. The ACC relies on your car’s computer software for its function and software glitches are common with many systems. You may experience issues such as unexpected shutdown or restart, incorrect information, or inability to recognize vehicles when the ACC’s software system begins to glitch. However, you can easily fix this issue with a simple system restart or reboot.
How to Deal with Adaptive Cruise Control Failure in Your Volvo
If you notice that your car’s ACC is not as effective as it used to be or you suspect there’s a problem, here are some tips to help you handle the situation:
- Start by cleaning the windshield, radar sensor, and camera. This helps to remove any dirt or debris that may be blocking the ACC system.
- Look for obstructions and remove them. Sometimes, you may have unconsciously added some obstacles to the windshield, preventing the ACC from functioning as it should. Some common obstructions are decorative items, stickers, or frames.
- Check for physical damage to the sensor and camera as this can happen on hard impact. Also, look out for blown fuses and replace them as required.
- Reset the system. A system reset may be all you need to get the ACC working again. You can check the owner’s manual for the location of the reset or default button.
- Have our professionals inspect your ACC to ensure you’re safe while using the feature.
