Snap Shot Mode Operation
PCM/ECM CODE SNAPSHOT
The PCM/ECM snapshot mode gives the ability to view the PCM/ECM parameter values either when a code set or at a particular instant of time as
chosen by the technician. Snapshot captures all parameter values that were stored in the keep alive memory when a code was set. If more than one code
sets, the values associated with the last code will be stored with an "L" prefix (i.e. L.0.1 or L.0.2 etc.).
