PCM/TCM Malfunction History

PCM/TCM Malfunction History:

The PCM/Transaxle Controller (TC) will store important information when certain malfunctions are detected. This information allow one to determine what vehicle operating conditions existed when the fault occurred.

These parameters are normally read with the Saturn Portable Diagnostic Tool (PDT) which is the Saturn Scan Tool. Check with your scan tool documentation to see if these parameters can be read with your tool.
