Accessing OBDII Data
From the Start Menu, select OBDII
Session using the up and down
arrow keys, then press Enter.
Follow the screen instructions, and
turn the Ignition Key to the ON
position, or start the engine. Press
Enter.
Once you press enter the Scan
Tool will try a number of different
communication protocols to establish
a connection with the vehicle. Even
though OBDII is a “standard” for
vehicle communication, there are
multiple languages that make up
the OBDII specication.
Once communication has been
established with the vehicle, the Scan
Tool will display the results of the
comprehensive readiness monitor. If
any of the readiness monitors have
failed, or are pending, the screen
will say “NOT all system readiness
tests have been completed. Press
Enter when you are nished with this
screen.
The OBDII Session screen is now
displayed. At this point you can
select Datastream, Trouble Codes,
Readiness Monitors, Test Modes, or
Disconnect from the menu.
