• At the next screen, select the desired data list (e.g. Engine Data 1, Engine Data 2,
EGR Data).
• At the next screen, select trigger type and trigger point, as described on the next
page. Note that your choices may be limited depending on the application.
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 Tech2 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.
6. Press the Record Snapshot soft key. The Tech2 screen will display the flashing
message “standby.”
• When the fault occurs, press the Trigger soft key.
• The Tech2 will display the message “triggered.”
• Allow the scan tool to record a sufficient amount of data, then press [EXIT] to store
the snapshot data.
• Press the Continue soft key when the snapshot trigger type screen is displayed.
7. Exit to the Main Menu, then power down and disconnect the Tech2 from the vehicle.
Uploading the Snapshot to the PC
After a snapshot has been successfully captured, perform the following steps to upload it
from the scan tool to the computer.
1. Launch TIS2Web.
2. Select Snapshot Upload/Display from the TIS2Web main screen.
3.
Select the “Upload from Handheld” box in the center of the screen, or select the Upload
from Handheld icon on the Snapshot toolbar.
4. Select Tech2
on the “Upload from a Handheld Device” window, verify that the Tech2 is
connected to the computer, and then select OK.
5. Select the snapshot to be uploaded, then select OK.
6. After the snapshot uploads, a list of data parameters will display on the monitor.
