PCM Snapshot Using A Scan Tool

The scan tool can be set up to take a snapshot of the parameters available via serial data. The snapshot function records live data over a period of time. The recorded data can be played back and analyzed. The scan tool can also graph parameters singly or in combinations of parameters for comparison. The snapshot can be triggered manually at the time a symptom is noticed, or set up in advance to trigger when a DTC sets. An abnormal value captured in the recorded data may point to a system or component that needs to be investigated further. The snapshot will remain in the scan tool memory even after the tool is disconnected from its power source. Refer to the scan tool user instructions for more information on the snapshot function.
