Datastream

Select Datastream from the OBDII

Session Menu and press enter.

The Scan Tool will search for data

and display what it has found. For

each item of data, the Scan Tool will

display the ECU Number, Name and

Value. The ECU number indicates

which ECU in the vehicle is reporting

the data. It is not uncommon for the

transmission to display RPM, and

Throttle position in conjunction with

the main ECU on the vehicle. The

ECU number helps you notice the

difference. The name is displayed in an abbreviated manner. To learn

the full name of the data bit, just use the up and down arrow keys to

highlight the data bit and read the expanded description at the bottom

of the screen. The value is the actual data as recorded by the ECU.

The Scan Tool has the ability to lock up to 3 lines of data on the screen.

For example, if you want to see

RPM, and vehicle speed all of the

time, simply scroll down until the data

is highlighted, then press the Enter

key. Once the Enter Key is pressed,

a lock symbol will appear and the

selected data will jump to the top of

the list. Up to three lines of data can be locked on the screen at any

one time. To unlock the data, scroll to the top of the data list, select the

line you want to unlock, and press the Enter key again.

In the upper right and lower right of the Datastream screen, a small arrow

will appear to help you know where in the data list you are scrolling.
