6. Press the Record Snapshot soft key. The Tech 2 screen will display the flashing message “standby.”

7. Exit to the Main Menu, then power down and disconnect the Tech 2 from the vehicle.
Trigger Type (F0 - F3 function keys) determines how the snapshot is triggered:
F0: Manual Trigger triggers a snapshot when you press the Trigger soft key.
F1: Any Code triggers a snapshot whenever any current trouble code is stored. This event occurs
when the first code is stored in the vehicle controller memory.
F2: Single Code triggers a snapshot when a user specified trouble code is stored.
F3: Automatic Trigger (chassis applications only) automatically triggers a snapshot.
Trigger Point (F4 - F6 function keys) is the exact point at which the trouble code (fault) or manual
trigger occurs within the snapshot period. It helps to know the trigger point when you are looking for
changes in data parameters. Trigger point may be set for:
F4: Beginning causes the Tech 2 to start recording information from the trigger point until
snapshot storage is full. This choice is useful if the fault is predictable.
F5: Center is the most commonly used trigger point because it stores information leading up to
and following the trigger point. This function allows comparison of events before, during, and
after a fault.
F6: End sets the trigger point at the end of the snapshot recording and therefore shows only
information leading up to and including the fault.
