Event data recorder
Your vehicle has computers that monitor and control cer-
tain aspects of your vehicle. These computers assist in
driving and maintaining optimal vehicle performance. Be-
sides storing data useful for troubleshooting, there is a
system to record data in a crash or a near car crash
event. This is called an Event Data Recorder (EDR).
The SRS airbag sensor assembly contains the EDR. In a
crash or a near car crash event, this device may record
some or all of the following information:
! Gasoline engine speed
! Whether the brake pedal was applied or not
! Vehicle speed
! To what extent the accelerator pedal was depressed
! Position of the transmission selector lever
! Whether the driver and front passenger wore the seat
belts or not
! Driver’s seat position
! Front passenger’s occupant classification
! SRS airbag deployment data
! SRS airbag system diagnostic data
The Electronic Control Unit (ECU) of the electronically
controlled brake (ECB) may contain another EDR. There
are a variety of driving situations which include activating
the ECB under which the ECB EDR will record certain
information. The ECB EDR may record some or all of the
following information:
! Behavior of the vehicle
! Steering wheel angle
! Vehicle speed
! To what extent the accelerator pedal was depressed
! To what extent the brake pedal was applied
! To what extent the ECU controlled the condition of
the 4 wheels
! Vehicle stability control diagnostic data
