Data Display
Depending upon the test vehicle, this selection may appear as Data, Data Display, Data Only,
Data (No Codes), or something similar. All are similar. Selecting has one of the following results:
•
A submenu of data viewing choices displays.
•
Vehicle data displays.
A submenu displays when more than one data viewing mode is available on the identified vehicle.
On some models, the engine must be started or cranked before data can be displayed. For these
models, a “Waiting to Communicate” message displays if the engine was not cranked or started.
Data Screens
When a Data selection is made, the screen displays the data list for the selected module.The
items available for any electronic control module vary from one vehicle to another.
Data is presented in a 2-column format. An abbreviated parameter name is at the left of each
column and its value is at the right edge of the column. Parameters display in the order that they
are transmitted by the ECM, so expect variation between vehicles.
Gesture scrolling allows you to quickly move through the data list. Simply touch the screen and
drag your finger up or down to reposition the parameters being displayed. Position bars
momentarily appear to the right of each column to indicate the position of the current screen in
relation to the entire list as you scroll. Each column of parameters scrolls independently of the
other column.
