Event Data Recording Devices - Mack Granite GU Series Operator's Handbook Manual

EVENT DATA RECORDING DEVICES

Your MACK vehicle is equipped with a device generally referred to as an
"event data recorder" or "EDR." Please note that while the term "event data
recorder" is typically used throughout the motor vehicle industry, not every
EDR is the same; i.e., they do not all record the same data elements. The
EDR on your MACK vehicle records vehicle speed, engine rpm, time and
date, plus a variety of pedal and switch positions, both before and after an
"event." Sudden vehicle deceleration or the occurrence of certain other vehicle
operational characteristics will define (trigger) an "event."
Optional equipment available for your MACK vehicle, such as the Eaton®
VORAD® Collision Warning System, may also provide event data recording
features.
If you have a question about your EDR, please contact your MACK dealer or
regional service office.
