The Importance of ADAS Calibration After A Wheel Alignment

Many modern vehicle models require ADAS recalibration after a wheel alignment. Proper alignment can influence how ADAS safety features work in your vehicle. Your vehicle’s alignment can directly affect the performance of your ADAS features, especially lane keep assist and collision braking.  It is important to know if your vehicle will require an ADAS recalibration after a wheel alignment by calling our experts.

Wheel Alignments Adjust Your Steering Wheel Sensor Which Impacts ADAS

Do I Need To Recalibrate My ADAS After A Wheel Alignment?

ADAS cameras and sensors receive feedback from different vehicle parts to function, such as input from the steering angle sensor. The steering angle sensor transmits the steering wheel’s angle, turn rate, and other data to your vehicle’s internal computer. Certain ADAS features like lane keep assist may be activated based on the input received.

Vehicles equipped with ADAS need their system to be in sync with how the vehicle is traveling down the road. ADAS calibration after a wheel alignment may be required, as steering wheel sensors are often adjusted during the alignment process. Without recalibration, your ADAS may think your steering wheel is turned a certain way even when it is not. This can cause your ADAS features to perform incorrectly, putting you and your passengers in danger.

Let’s use lane keep assist as an example. If your vehicle pulls to the left or the right, lane keep assist will work to correct your vehicle’s trajectory back toward the center. But what if your vehicle is driving straight down the road and your ADAS camera or steering angle sensor is miscalibrated? Your vehicle may try to self-correct itself, even when correction is not required. This could lead to collision or injury due to incorrect road feedback.

ADAS sensors and cameras are directly affected by a vehicle’s wheel alignment. Your ADAS features may depend on accurate input from your steering angle sensor to work correctly. For this reason, we recommend having your ADAS recalibrated anytime the steering angle sensor is adjusted, which commonly happens during a 4 wheel alignment.

In addition to re-calibrating after a wheel alignment, your ADAS may need to be re-calibrated after a fault code, a disconnect, a change of suspension, or after a replacement windshield is installed.

Understanding the Importance of ADAS Calibration After Windshield Replacement

An Advanced Driver(s) Assistance System, or ADAS, consists of various safety features designed to work together to prevent accidents and injuries. Your ADAS must be recalibrated following a windshield replacement so that certain safety features work correctly.

What is ADAS, and Why Is It Important?

ADAS (Advanced Driver Assistance Systems) safety features are designed to work together to enhance vehicle safety. Feedback is received from the road through windshield-mounted cameras, radars, sensors, and lasers. ADAS features will utilize this feedback and alert or assist the driver in helping them avoid potential problems and collisions. Some common ADAS features include:

  • Adaptive Cruise Control
  • Adaptive Headlighting
  • Blind Spot Monitoring
  • Collision Assist (Front and Rear)
  • Driver Drowsiness Monitoring
  • Lane Departure Warning
  • Lane Keep Assist
  • Park Assist
  • Pedestrian Detection
  • Traffic Sign Recognition

How Does Windshield Replacement Impact ADAS?

ADAS features rely on feedback from the road to operate. These cameras are often mounted onto a vehicle’s windshield and other areas, such as the rear and front bumpers and side mirrors. 

To install a replacement windshield, our technicians will need to remove the original, damaged windshield and then install the new replacement. In doing so, any cameras, sensors, radars, etc., that are mounted to the windshield will need to be removed from the damaged windshield and then reattached to the new windshield. This windshield replacement process will affect the accuracy of your ADAS readings, which can directly impact driver safety. Please consider the following about ADAS Calibration and Windshield Replacement.

  • If windshield-mounted cameras are not appropriately calibrated, ADAS safety features may not work as designed. The driver may receive inaccurate information. This puts the driver, their passengers, and other drivers at risk. 
  • Auto manufacturers specify which cameras need to be recalibrated after a windshield replacement. 
  • Without accurate road feedback, front-facing reliant ADAS features will not work as intended.

Imagine that you have a replacement windshield installed but do not recalibrate your ADAS after the fact. These ADAS features will still work, but they will be basing their alerts on inaccurate road feedback.  Each vehicle manufacturer lists specifications for how an ADAS needs to be synched with its internal system. Having these cameras and sensors misaligned, even if only slightly, is cause for concern.
