(Part 2 Of 2):

TYPICAL SCAN TOOL DATA VALUES
Use the typical Scan tool data values listed in this section for a comparison after the Instrument Cluster System Check and finding the system is functioning properly with no diagnostic trouble codes displayed. The typical scan tool data values are an average of the displayed values recorded from normally operating vehicles. The typical scan tool data values are intended to represent what a normally functioning system would display with certain preliminary settings. The values you get may vary slightly due to a low battery charge or other reasons. But the values should be very close.

Use only the parameters listed in the tables for diagnosis. It a scan tool reads other parameters, the values are not recommended for use in diagnosis.
