After selecting the data List type, press
the
ENTER
key to start playing back the
recorded data.
The Playback Data screen has a
Vehicle Data List header that marks the
beginning of the data list. On the Playback Data screen, lines 1-3 are used to
display vehicle data parameters. The fourth line displays the Frame number and
Time in seconds.
Negative frames and timestamps indicate data recorded before the trigger
event. Positive frames and timestamps indicate data recorded after the trigger
event.
Use the
UP/DOWN
arrow keys to view the recorded PID data of each frame. The
end of the list is reached when only the
] (up) icon is visible.
Use the
LEFT/RIGHT
arrow keys to scroll back and forth through the frames.
The
RIGHT
arrow key advances to the next frame, “wrapping around” to the
earliest frame when the final frame is reached. The
LEFT
arrow key goes back
to the previous frame, again “wrapping around” to the final frame.
✓ After reaching the last time interval recorded. The Time display will
change from data recorded after trigger to data recorded before. This is
normal. The
LEFT/RIGHT
arrows may be used to scroll through all time
intervals in either direction.
The Frame index is very similar to the Time index. A Frame is a “snapshot” of
engine operating conditions at that moment. The Frame number increases
every time the vehicle’s PCM transmits data across the communication link.
Remember, not all Ford vehicles use the same number of PIDs. For this reason,
not all vehicles will start and end with the same Frame number. The vehicles
with less PIDs will have the greater Frame number range. Like the Time index,
Frame 0 is the trigger point. Thus, negative Frame numbers contain data prior
to the trigger point, and positive Frame numbers contain data after.
If you wish to change the Custom Data List parameters, press the
BACK
key
to return to the Playback Data As: menu. When you have finished playing back
a recording, press the
FUNC
key to return to the Ford Function List.
