Event data recorder
In a crash or a near crash eventThe SRS airbag sensor assembly co ntains the EDR. In a crash or near
crash event, this device may record so me or all of the following informa-
tion:
● Engine speed
● Whether the brake pedal was applied or not
● Vehicle speed
● To what extent the accelerator pedal was depressed
● Hybrid transmission shift position
● 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 abov e is intended to be used for the purpose of improv-
ing vehicle safety performance. Unlike general da ta 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 assist in driving and maintaining optimal
vehicle performance.
Besides storing data usef ul for troubleshooting, there is an event data
recorder (EDR) that records data in a crash or near crash event.
