EDR (Event Data Recorder)

The airbag sensor assembly monitors and control certain aspects of the 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 the Event Data Recorder (EDR).
The 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:

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 seat belts or not

Driver’s seat position

SRS airbag deployment data

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.

Toyota will not disclose the data recorded in an EDR to a third party except when:


An agreement from the vehicle’s owner (or the leasing company for a leased vehicle) is obtained

Officially requested by the police or other authorities

Used as a defense for Toyota in a law suit

Ordered by the court

However, if necessary Toyota will:

Use the data for research on Toyota vehicle safety performance

Disclose the data to a third party for research purposes without disclosing details of the vehicle owner, and
only when it is deemed necessary

Disclose summarized data cleared of vehicle identification information to a non-Toyota organization for
research purposes

 

Especially if the other guy is whom you hit (or hit you) is claiming otherwise.
