Data Screens
When a Data selection is made, the screen displays the data list for the selected module.The
items available for any 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 touching the screen and
drag your finger up or down to reposition the parameters being displayed. Position bars to the right
of each column indicate the position of the current screen in relation to the entire list. Each column
of parameters scrolls independently of the other column.
