Snapshot In On-Board Diagnostics
RECORDING AND RETRIEVING SNAPSHOT DATAPowertrain Control Module (PCM) snapshot data may also be taken and retrieved while in on-board diagnostic mode by selecting the "PCM SNAPSHOT" option. If no customer and PCM code snapshots are saved, or if they are not selected, "TAKE PCM SNAPSHOT" will appear. Selecting "TAKE PCM SNAPSHOT" will record all data and input parameters. These parameters may then be viewed right away. This snapshot will only be saved while in on-board diagnostics. Exiting on-board diagnostics or turning the ignition "OFF" will erase a PCM snapshot taken while in diagnostics.
SELECTION AFTER SNAPSHOT
After the snapshot is taken, "PCM SNAP DATA" will appear. Select "PCM SNAP DATA" to view saved data parameters. If "PCM SNAP DATA" is not selected, "PCM SNAP INPUTS" will appear. Select "PCM SNAP INPUTS" to view saved input parameters. Keep in mind that once "PCM SNAP DATA" or "PCM SNAP INPUTS" is selected, 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.
NOTE: Taking a PCM snapshot will erase any Customer Snapshot data previously stored.
AFTER SNAPSHOT
