In the fourth quarter of 2007, Bosch released both hardware, and an update to its Crash Data Retrieval Tool software allowing users to download PCM data – including pre-collision data.
This paper presents methods to use in order to safely retrieve the data contained in currently support Ford PCM’s and methodologies used to interpret the retrieved data.

Introduction (slightly abridged)
Low speed
rear-end impacts resulting in minimal damage to the involved vehicles are common occurrences on our roadways. Claims, and/or litigation, involving neck and back injuries often result from these collisions. A surprising number of claims of injury result from impacts involving transit buses. Many transit bus collisions involve multiple claimants, who frequently claim whiplash-type injuries.
Because of the large number of often suspicious claims, the need for
low collision data became apparent. The impact severities speed car-to-busand the kinematics of the occupants involved in crash tests couldbe recorded and studied. This would help give thereconstructionist information needed to evaluate the injury potential fromreal-world accidents .
