Experienced shops will scan for codes before disassembling damaged cars.
While these shops are busy repairing crumpled fenders and waiting for paint to dry, they ship airbag modules and deployed SRS parts to MyAirbags for service. The majority of airbag modules we receive are from collision repair shops. If your car has been in an accident, the scan will generally indicate a range of soft and hard codes. A quick scan may reveal an easy-to-fix loose connection in the system. It is still useful for reading DTC fault codes. Your OBDII scanner is still very importantĪt the end of the day, your handheld OBD2 scanner simply cannot reset hard codes. OBD2 scanners - even high-end units from Autel and Snap-On - cannot reset Air Bag Module hard codes. Founded in 2006, MyAirbags has invested heavily in purchasing and developing the tools required to read and properly reset airbag modules. Likewise, there is no “one-size-fits-all” tool available to cover the gamut of vehicle makes and models. The equipment associated with servicing these electronic data recorders is not user-friendly. For instance, EDRs may record (1) pre-crash vehicle dynamics and system status, (2) driver inputs, (3) vehicle crash signature, (4) restraint usage/deployment status, and (5) post-crash data such as the activation of an automatic collision notification (ACN) system.”Ĭrash data is used by government agencies, vehicle manufacturers, insurance companies, and the medical industry to evaluate accidents after the fact and improve safety technology moving forward. According to the NHTSA, crash data is collected by the Electronic Data Recorder which is defined as follows: “…a device installed in a motor vehicle to record technical vehicle and occupant information for a brief period of time (seconds, not minutes) before, during and after a crash. Like the black box on an airplane, your vehicle stores crash data which can help investigators understand vehicle dynamics surrounding the time of the accident. “Hard” codes are associated with accident crash data. Hard Codes and EDR: Like the black box on an airplane As technology and regulation advance, newer vehicles have more SRS components than older vehicles. Otherwise, your airbag warning light will continue to illuminate. Deployed or faulty parts must be repaired or replaced in order to clear any “soft” error codes.
Soft DTC codes refer to faulty and or deployed safety equipment including airbags, seat belt pretensioners, collapsible steering column sensors, active headrests and rollover bars, and more. Hard codes refer to stored accident crash data. The first thing to comprehend is the difference between “soft” and “hard” DTC codes. Soft Codes and Hard Codes: What’s the difference?
