Applies To: ETHOS® PRO
Scanner Data PID View: Data Menu, PID View, Data Recording / Playback / Pause, Custom Data Lists, PID Sorting
Snap-on Training Solutions helps you get the most out of your ETHOS PRO diagnostic tool. This training module covers the use of scanner data in parameter ID view, also known as PID view.
The scanner data display shows the live data parameter information from the vehicles control module. To access live data, select Data from the scanner main menu. Depending on the vehicle, this may open a sub menu of viewing options. Remember, you can scroll down with the touch screen or key pad for additional selections. For this example, we will choose to view engine data from the sub menu. A list of engine data parameters is shown along with a brief description of each parameter. The data appears in a digital text format on the right called PID view. The data values refresh as the vehicle sends new data. The speed may vary depending on the speed of the data being sent from the vehicle and the number of data parameters being viewed. Scroll down to view all available data.
The data is continuously recorded for all data parameters. After 2000 frames are recorded, new data is recorded and overwrites the oldest frames of data. The pause button freezes the data display for closer examination and review. When viewing paused or recorded data, the left and right arrows move forward and back one data frame at a time. Move the position indicator to navigate to any part of the recorded data. The pause icon indicates live data from the vehicle is being displayed. Selecting the pause icon stops data collection. You also have the option to clear the data buffer and start over. This is useful when vehicle conditions change and you want to record and view new frames of data. Use the record icon to restart data recording at any time. Scroll down to view the complete list of data parameters at any time the live data is playing, or when it is paused.
Here are the rest of the engine data parameters for this vehicle. You can choose data parameters you want to view together on one screen. Just highlight any parameter and select the lock icon to lock it on top of the screen. Scroll down and lock to select additional parameters. This enables you to see relationships between data parameters. Simply select the lock icon again, to unlock a parameter.
The custom data list function gives you even more power to customize the view. Selecting the custom data list checkmark opens a menu for selecting parameters to display. Check marks to the left of the data parameter description indicate which parameters are selected for display. Here we see the select all icon, use it to hide or display all the data parameters. Touch once to select all data parameters in the list. Touch again to de-select all parameters in the list. Touch the select button on the toolbar to add a parameter to the custom data list. Touch it again, to delete the checkmark and delete the parameter from the list. Select as few or as many as you want. When you have created your custom data list, use the back arrow to return to the data, display and view the list. Custom data lists can significantly accelerate the speed of the data display by processing only the vehicle data that you need. So you can find tough intermittent failures, faster.
The sort function is another handy way to find and view the parameters you need. Select the Sort icon to sort the list by the factory default sort order or from A to Z or Z to A.
