3. Notice the following about the Live Data
screen:
Each line displays a data item.
You use the PG Up and PG Down Direction
buttons to scroll through the page of data and
use the stylus pen to select lines (one line at a
time).
The screen’s data updates as the software
reads from the vehicle’s ECU. Each update is
called a “frame” of data.
You can stop and start the live readings at any
time by clicking on the Pause button. When
you stop the readings, the data “freezes” on
the screen.
The function keys and options at the top and
on the right of the screen allow you to
perform several other functions on the screen.
For details, refer to Sub-Section 3.3.2 Live
Data Functions on page 20.
4. When you are finished using the screen, click
on ESC to return to the Function Menu
screen.
