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

Written by Toby Chess


The answer is yes. Take a look at what Fiat-Chrysler Corp has to say about scanning.

“Safety and security related systems, such as antilock brakes, supplemental restraint systems (SRS – air bags), occupant restraint controller (ORC), seat belts, active head restraints, forward facing camera and radar, blind spot monitoring, and other automated electronic driver assistance systems, MUST be tested for fault codes (DTCs) that could be active (current) or stored following a collision. Use of the Mopar wiTECH vehicle diagnostic tester is necessary before and after collision repair.”

“Furthmore, voltage loss, collisions, significant vehicle disassembly, interior trim repair or removal, and glass removal and replacement operations could trigger DTCs prior to or during collision repairs, which could result in improper vehicle performance.” These two paragraphs were taken from the Fiat-Chrysler web site. Next, take a look at what Honda states about post scans.

“Any repair that requires disconnection of electrical components in order to perform the repair will require a post-repair diagnostic scan to confirm if the component is reconnected properly and functioning. Damage that requires body parts replacement will always require a post-repair diagnostic scan."


Remember, mirror switches,window switches,power door locks, fuel door switch, and trunk switch can be attached to a door trim panel and they are connected to a computer module that uses electrical current to operate.




Any of these items could set off a diagnostic trouble code (DTC).  If you do not think this is nuts, look at the next flow chart from Honda.
