Use the scan tool data listed in this table for comparison after the Powertrain On-Board Diagnostic (OBD) System Check and finding the on-board diagnostics function properly with no diagnostic codes displayed.
The Typical Scan Tool Data Values are an average of display values recorded from normally operating vehicles. The Typical Scan Tool Data Values are intended to represent what a normally functioning system would display. The values you get may vary due to a low battery charge or other reasons, but they should be close.
Do not use a scan tool that displays erroneous data. Report the problem to the manufacturer. The use of a malfunctioning scan tool can result in misdiagnosis and unnecessary parts replacement.
Use only the parameters listed in the tables for diagnosis. If all values are within the range illustrated, refer to Symptoms .
