PCM Snapshot Using A Scan Tool
Description
PCM snapshot data may also be taken and retrieved using a diagnostic tool by selecting the Snapshot option. These parameters can then be reviewed at
any time.
Operation
Keep in mind that once a Snapshot is triggered, the parameter and input data displayed will look just like the normal PCM parameter and input data with
the same parameter numbers except it will not vary since it is displaying recorded data.
