Do You Know Your Terms? Scanning, ESC, SAS and ADAS

Written by Toby Chess

What if a vehicle was involved in accident and your shop repaired the vehicle, but failed to scan it and make sure that all of the ADAS were in operation. Who would be liable if the same vehicle was in another accident and wound up in litigation? You of course. I know that scanning is the buzz word today, but is it something new? The answer is NO.

At first there were few standards and each manufacturer had their own systems and signals. In 1988, the Society of Automotive Engineers (SAE) set a standard connector plug and set of diagnostic test signals. The EPA adapted most of their standards from the SAE on-board diagnostic programs and recommendations. OBD-II is an expanded set of standards and practices developed by SAE and adopted by the EPA and CARB (California Air Resources Board) for implementation by January 1, 1996.

 

What is ESC?

 

ESC (Electronic Stability Control) is constantly monitoring how the vehicle is responding to the driver and road conditions. If a problem starts to develop, it takes whatever measures that are necessary to bring the vehicle under control. The engine power is reduced letting off of the throttle, retarding the timing and simultaneously applying the brake. All these processes coupled together will counter the forces that are causing the vehicle to lose traction or control. This whole process is accomplished without the driver’s input.
