Minimum and maximum values are stored even after the data has scrolled off the screen.Įngine Data Screen with PID Trigger Icon highlighted Values to the left of each graph show the current, maximum and minimum value of captured data. All data is continuously being recorded for all available parameters for the selected ECM. Scroll down for more data, using the scroll bar on the right. Multiple graphs allow you to view relationships between components. The graph provides a large number of data points plotted so you can compare events over time. Live Data Screen – 4 Graph View with View Selection menu From one to four graphs can be displayed on the screen. The View icon switches the live data viewing mode between a numeric view and a graphing display. Live Data Screen - PID List with View Selection menu Data graphing can show momentary failures, and data trends over time. Graphing relationships between data parameters gives you a view of performance over time. Live data is one form of “back door” information, or data that is output from the vehicle electronic control module, or ECM.Ī numeric view of Parameter ID, or PID data, will not always reveal problems or show relationships between PIDs. Live data parameters are some of the most valuable clues to help track down a vehicle fault. This module is designed to help you get the most out of your MODIS Edge diagnostic tool, and covers the use of scanner data in graphing view.
