What is the electronic data recorder?
Your car has a number of pretty advanced systems onboard, such as the SYNC system. It also has an electronic data recorder, or EDR. This is a computerized device that works sort of like the “black box” in an airplane. It doesn’t record anything but crash and near-crash data, however. The system records about 30 seconds of data for use in crash analysis, including the following:
The operation of vehicle systems
What seat belts were buckled
How far the gas pedal was pressed in (if it was at all)
The speed of your car
The steering wheel position
The EDR only records data during crash and near-crash situations. It doesn’t record at any other time.
