US: Toyota clarifies facts about its EDRs

There are a variety of EDRs installed on Toyota and Lexus vehicles in the U.S. today. The data that is recorded and that can be read out and analyzed differs depending on the type of EDR that is installed in a particular vehicle and when the vehicle was manufactured.

Although there are a variety of EDRs installed on Toyota and Lexus vehicles in the U.S. today, EDRs can generally be split into two groups: those that record only post-crash data, and those that record pre- and post-crash data. In both cases, the EDRs record data only for collisions that meet certain criteria that are based on the severity of the collision.

While the large majority of Toyota and Lexus vehicles have EDRs equipped to record both pre- and post-crash data, several models have EDRs that do not record pre-crash data. Therefore, data regarding vehicle speed, engine speed, accelerator angle and brake application is not available in every make and model.

However, by the end of 2010, all newly-manufactured Toyota and Lexus vehicles will have EDRs that can record both pre- and post-crash data.

Toyota has always provided all data recorded by the EDRs to the National Highway Traffic Safety Administration (NHTSA), law enforcement authorities, and courts when requested or ordered to do so.

Contrary to some media reports, Toyota does not deliberately provide printouts of data with key columns left blank. In some cases, data columns have been blank because data for the column did not exist. This is not an omission, but is due to the specifications of the EDR installed in the vehicle concerned.
