ASA Partners With Bosch for 5th, Final Webinar: Recalibrating Driver Assistance Systems

Written by



On Wednesday, May 16, the Automotive Service Association (ASA) partnered with Bosch for the fifth and final webinar of their series on scanning: “Recalibrating Driver Assistance Systems: The Road to Repairing Autonomous Vehicles – Collision Avoidance System Recalibration.” 

ASA Vice President Tony Molla began the webinar by welcoming attendees and thanking Bosch’s Doc Watson and Pat Pierce for their patience throughout the series. He reminded attendees that the webinar would focus on key procedures for both collision and mechanical repair and that the tips provided also apply to other brands of scan tools. 

Before starting the training video, Watson shared, “As a representative for Bosch, we’re happy to have as many attendees as we do today. This is a big topic in our industry, and whether you’re in collision [or] mechanical repair, it applies to all of us.”

The video began by looking at the ADAS systems being used today and defining a long list of enhanced features and technology that are integrated into modern vehicles. Bosch’s stance on scanning aligns with most OEMs’ position statements that support pre- and post-scans of vehicles to help identify potential collision and non-collision related DTCs. It also supports reporting all DTCs to the vehicle owner and the insurance company. 

Discussing adaptive lighting systems that could have several sensors located in many different areas of the vehicle, Watson shared common locations and how to determine when calibration is necessary. He also discussed common locations for blind spot sensors that monitor the location of other vehicles that the driver cannot see. Calibration of this feature often includes removal of the sensor as well as removal of the bumper cover to avoid damaging the mounting location.

Regarding forward radar sensors, it is important to monitor the forward distance of objects in front of the vehicle and to control the following distance because systems use this data when calibration is required. Park assist sensors---ultrasonic sensors located in the front and rear bumper covers---monitor the distance between the vehicles and other objects, and calibration or aiming may need to be done after removal of the bumper cover, removal of the sensor or an impact on or near the sensor.
