Using the procedures laid out by the OEM you can take into consideration the time, cost, tool, information and space requirement to perform these procedures. Moving right along, we can address the question of what is required to get the job done. I have worked with a fair number of shops that have attended ADAS classes. I’ve attended some myself. What I can tell you with certainty is these classes have truth and fiction in them. The problem for an instructor trying to put one of these classes together is the amount of time available and the number of systems that can be covered in a class. Considering that an OEM can change the procedure from model to model and year to year, most instructors don’t have the time to cover all the different systems.
To be considerate of time and maintaining the audience's interest, it is easier to build and present a class that addresses the technology in a general manner. I’m not saying don’t go to one of these classes or that they are not good. I’m saying that now that you have some understanding, it’s time to consider going to more classes and reading more articles. As you do this, you should start seeing some contradictions. When you are at a class or read an article that contradicts what you’ve learned before, that is the time to ask questions to the person making the statement. Trainers and those writing articles need to be challenged. The conversation will hopefully lead to a more complete understanding, maybe by both parties.
I was recently at a shop that requested MAS service on a Lexus that had been in a front-end collision. This model had all the bells and whistles. The windshield replacement required that the lane keep system to be calibrated. The ACC (adaptive cruise control) module was replaced requiring another calibration but that is not where it ended. Having Lexus intelligent clearance sonar means if the bumper or sensor is replaced, one more calibration is needed. Three calibrations for this Lexus was a supplement I’m sure nobody was prepared for. Is your shop applying the knowledge from classes when the vehicle is in the estimating process or towards the delivery end? Having a sense of what is needed during the estimating process is going to help with unwanted supplements and help with cycle time.
Considering Toyota is installing collision prevention on Corollas, it’s time to get in front of the issues these systems are presenting. In my opinion, the best way to do this is to start with a pre-scan. Having a technician or company that is trained to use the diagnostic information and have understanding of what types of disassembly the repair will require should allow the estimator to include any calibrations needed into the repair estimate. Hopefully, whoever is tasked with any needed calibrations will also include a post-repair vehicle scan.
