Information Contained in the EDR

The type of data that may be available in an HV EDR generally are dependent on four factors:

• Brand of engine
  • For example: Detroit Diesel, Cummins, Caterpillar.
• Type of engine control module
  • This is usually dependent on the year model of the engine and ECM/EDR.
• Settings the end-user has (or has not) selected
  • For example: deceleration rate required to record data, data recording on/off.
• Specifics of the crash in question
  • Not all types of accidents can be expected to trigger data recording. Some accidents may be so severe that the ECM is destroyed.
