PCM/ECM SNAPSHOT
Used to diagnose intermittent conditions, the snapshot selection will store one set of all the PCM/ECM data parameter values and output status
indications at the time that the snapshot is requested. To enter snap-shot mode, enter diagnostic mode, then push "LO" until "ECM SNAP-SHOT?" is
displayed and then push "HI", "EXXX SNAPSHOT?" will then be displayed. The "XXX" is the 3 digit diagnostic code that recorded the snapshot. Push
"LO" again, and "TAKE ECM SNAPSHOT?" will be displayed. When the intermittent condition occurs, or when the parameters are to be recorded,
press "HI" and hold until the message "Snap-shot Taken" appears. The "Snapshot Taken" message indicates that the data is now stored for review.
