Most late model cars have a partial VIN stored in the Diagnostic Energy Reserve Module.
What is a DERM (Diagnostic Energy Reserve Module)?
The DERM is General Motor’s fancy term for an airbag module. This is important safety module which controls air bag deployment. During a collision this module receives information from the impact sensors, which then relays a signal to deploy the airbags. The airbag sensor is then locked until it is either replaced or reprogrammed.
