PART 563_EVENT DATA RECORDERS--Table of Contents
 
Sec.  563.9  Data capture.

    The EDR must capture and record the data elements for events in 
accordance with the following conditions and circumstances:
    (a) In an air bag deployment crash, the data recorded from any 
previous crash must be deleted (both events). The data related to the 
deployment must be captured and recorded. The memory must be locked to 
prevent any future overwriting of these data.
    (b) In an air bag non-deployment crash that meets the trigger 
threshold, delete all previously recorded data in the EDR's memory. 
Capture and record the current data, up to two events. In the case of 
two events, detection of the second event starts after the End of Event 
Time for event 1.
