- As a result of fire damage or other trauma, electronic crash data recorded to an airbag control module’s (ACM) memory may be inaccessible by traditional imaging. These methods include traditional imaging through a vehicle’s diagnostic link connector (DLC) or accessing the electronic crash data directly through the ACM. Previous literature explored recovering electronic crash data from ACMs containing eight-pin small outline integrated circuits (SOIC8) electronically erasable programmable read-only memory (EEPROM). The current literature explores new methods to extract and clone hexadecimal electronic crash data from multipurpose complex memory chip, without the need to remove the subject complex memory chip. The hexadecimal raw data can be harvested, preserved, and even implanted into surrogate ACMs. This research explores non-destructive methods to clone ACMs using subject hexadecimal data for the purpose of extracting electronic crash data without disturbing the subject modules memory chip. The methodology presented in this paper will be tested and explored on many common passenger vehicle ACMs and pin-out diagrams for the respective modules are included. The electronic crash data obtained from the imaging of the subject module and the subsequent cloned modules were compared and further analyzed.
