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:
l Engine speed
l Whether the brake pedal was applied or not
l Vehicle speed
l To what extent the accelerator pedal was depressed
l Position of the transmission shift lever
l Whether the driver and front passenger wore seat belts or not
l Driver’s seat position
l Front passenger’s occupant classification
l SRS airbag deployment data
l SRS airbag system diagnostic data
If your vehicle is equipped with a vehicle stability control (VSC) sys-
tem, its Electronic Control Unit (ECU) may contain another EDR.
There are a variety of driving situations which include activating the
vehicle stability control (VSC) under which the VSC EDR will record
certain information. The VSC EDR may record some or all of the fol-
lowing information:
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 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).
