A recent webinar highlighted the importance of Advanced Driver Assistance Systems (ADAS) calibrations and why your technicians should have a record of what they’ve done during the process. The webinar featured Brent Johnson, Chief Collision Technology global product management director, and was sponsored by the Collision Industry Electronic Commerce Association (CIECA).
Ed Weidmann, CIECA executive director started the presentation, “ADAS Calibrations—Do It Right and Document What You Do” by introducing Johnson. Johnson began by defining the following:
- ADAS – Advanced Driver Assistance Systems;
- Static Calibration – A Calibration Method that uses predefined targets, locations and distances from the vehicle along with special software to Calibrate an ADAS; and
- Dynamic Calibration – Placing the vehicle in calibration mode and driving a preset distance/time, traffic density and marking pattern.
“ADAS need a real-world reference,” said Johnson, as he was comparing the program’s need for training to teaching a teenager to drive.
“At distances needed for safety, small errors create big problems. If you’re going down the road and have a very small error, the system reacting improperly or failing to react will create havoc on the road,” Johnson added. “All vehicles are calibrated in the factory using static calibration methods, so this gives the vehicles, as they’re coming off the production line, a real-world reference.”
According to Johnson, most systems do have artificial intelligence and have the ability to learn. He did note: that “like a teenager driving, it will take them a little while to pick up what they should and should not ignore.”
ADAS should be calibrated if a sensor has been replaced or reoriented, if a vehicle has sustained structural damage and has been repaired, or if the sensor is behind the windshield, panel or facia that has been repaired or replaced, according to Johnson.
Johnson also highlighted a few reasons to keep documentation of ADAS calibrations. He said that for each repair the technician should keep track of who performed repairs on the vehicle, including scanning and calibrations, along with their training level. Auto glass records should also state all repairs that were done to each vehicle, according to Johnson.
“Part of your quality control procedures should include making sure that your calibration tool software is up-to-date, and then document when those updates happened and what version of the software you used. It could save you a great deal of grief in the future if you can prove that you were using the current software version at the time that the calibration took place,” Johnson said.
