5−1. Essential information
Event data recorder
In a crash or a near car crash event
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 follow−
ing information:
lEngine speed
l
Whether the brake pedal was applied or not
lVehicle speed
l
To what extent the accelerator pedal was depressed
l
Position of the transmission shift lever
lWhether the driver and front passenger wore seat belts or not
l
Driver ’s seat position
l
Front passenger ’s occupant classification
lSRS airbag deployment data
l
SRS airbag system diagnostic data
The information above is intended
to be used for the purpose of
improving vehicle safety performance. Unlike general data recorders,
the EDR does not record sound data such as conversation between
passengers.
Your vehicle has computers that monitor and control certain aspects
of your vehicle. These computers assi
st in driving and maintaining
optimal vehicle performance.
Besides storing data useful for tr oubleshooting, there is a system to
record data in a crash or a near
car crash event. This is called an
Event Data Recorder (EDR).
