An airbag control module is an important part of your vehicle. In addition to storing crash data and sending cut-off signals to your engine following a crash, it also deploys your airbags. If you have been in an accident where the airbags were set off, you will need to replace the airbags and the SRS airbag control module in order to make the car safe to drive again. It is always best to send your original module for reset after an accident. Because your original module is already programmed to your vehicle and will not need additional programming after you get it back. If you purchase a new or used airbag module it may need to be programmed to your vehicle. This can be done on your vehicle. We will not be able to program it to your vehicle. Be sure to match part numbers of your replacement module to your original control module. The part numbers need to match to work in your vehicle.
