Saving and Reviewing Scanner / OBD-II/EOBD Data Files
The following procedures are used when saving and reviewing data files for Scanner and
OBD-II/EOBD.
Saving Files
During normal operation, data from the vehicle’s ECM is continuously being stored in buffer
memory as it is displayed onscreen. Buffer memory is limited to a predetermined “total” size and
is displayed on the counter (located below the toolbar on the right side of the screen)
(
).
Selecting
Save
writes the stored buffer memory to a file. Saving data is useful when trying to
isolate an intermittent problem or to verify a repair during a road test. The saved file can be played
back (similar to a movie clip) by selecting
Previous Vehicles and Data
> View Saved Data
. See
, on page 53 for additional information.
NOTE:
i
The
Save icon
performs the same function as “Save Movie” function choice for the programmable
Shortcut
button, see
, on page 57 for details.
The saved data file can also be downloaded to a personal computer (PC) using the Mini USB jack.
Once connected to the PC, the data files can be printed, transferred, and copied using
ShopStream Connect. ShopStream Connect is an application that creates an interface between
the Diagnostic Tool and a PC. The ShopStream Connect application is available free online, see
the ShopStream Connect website information at the front of this manual for additional information.
