Snap-on Training Solutions helps you get the most out of your SOLUS Edge diagnostic tool. This training module covers the use of scanner data in graphing view.
Live data parameters are some of the most valuable clues to help track down a vehicle fault. Live data is one form of “back door” information, or data that is output from the Electronic Control Module, or ECM.
A numeric view of Parameter ID, or PID data, will not always reveal problems and or show relationships between PIDs.
Graphing relationships between data parameters gives you a view of performance over time.
Data PID View
Data graphing can show momentary failures, and data trends over time.
Live Data Screen - PID List with View Selection menu
The View icon switches the live data viewing mode between a numeric view and a graphing display. From one to four graphs can be displayed on the screen.
Live Data Screen - 4-Graph View with View Selection menu
The graph provides a large number of data points plotted so you can compare events over time. Multiple graphs allow you to view relationships between components.
Live Data Screen – 4 Graph
Scroll down for more data, using the scroll bar on the right. All data is continuously being recorded for all available parameters for the selected ECM.
Values to the left of each graph show the current, maximum and minimum value of captured data. Minimum and maximum values are stored even after the data has scrolled off screen.
Highlight Toolbar on Live Data Screen
The PID Trigger is a valuable tool to automatically capture data when a parameter value is outside of normal range.
Live Data Screen - Graphing with PID Trigger Menu
The Set Trigger command sets upper and lower values to start recording a data movie when the signal crosses the set value. This is similar to an OBD-II freeze-frame. To set a trigger, select the data parameter you want to use. Then tap the Trigger button and select Set Trigger from the dropdown menu.
Live Data Screen with upper trigger value +/-
Tap the plus and minus buttons on the toolbar, or use the up and down arrow buttons to position the upper trigger line to the desired level. Tap the checkmark on the toolbar, or press the Yes button, to accept the value.
Live Data Screen with lower trigger value +/-
The lower trigger level line will appear on the graph. Position the line to the desired level. Tap the checkmark on the toolbar to accept the lower trigger value.
Live Data Graph Screen with trigger lines
The trigger points will appear as horizontal lines across the designated parameter graph. Triggers can be set on up to three parameters at once.
Live Data Screen with Trigger menu: Arm Triggers
To arm the triggers, tap the PID Trigger button on the toolbar and select Arm Triggers from the dropdown menu.
Live Data Screen with Trigger menu: Triggers Armed (purple)
The trigger lines on the data graphs change color to indicate an armed condition, and any data point outside of your set conditions will pause data collection and save a recording.
Once triggering is armed, it remains on until you clear or disarm.
Home Screen
View Saved Data Screen
The recorded data movie is automatically saved. Tap the Previous Vehicles & Data icon on the home screen and select View Saved Data to review the movie.
Select a File to View
Select the movie file you wish to view.
Change to Graph View.
Use the scroll buttons to scroll forward or back through the collected data.
Scroll down to view more data parameters.
Highlight Toolbar on Live Data Screen
The Zoom icon incrementally increases and decreases the scale of the data being displayed.
Live Data Screen with Zoom Menu
Zoom Plus
Zoom Minus
Tap the zoom icon and select a plus level to zoom in for more detail. Select a minus level to zoom out and see more data.
Highlight Toolbar on Live Data Screen
The Save Icon saves any current screen information, along with all data stored in the buffer. Simply tap the Save icon. Then select View Saved Data to recall and view the data movie.
