5-1. Essential information
Event data recorder
In a crash or near crash eventThe SRS airbag sensor assembly co ntains the EDR. In a crash or
near crash event, this device may record some or all of the following
information:
● Gasoline engine speed
● Whether the brake pedal was depressed or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Position of the transmission shift lever
● Whether the driver and front passenger wore seat belts or not
● Driver’s seat position
● SRS airbag deployment data
● SRS airbag system diagnostic data
● Front passenger’s occupant classification
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 an event
data recorder (EDR) that records data in a crash or near crash
event.
