Typical Scan Tool Data Values
Use the Typical Scan Tool Data Values listed in this section for comparison after the BCM Diagnostic System Check and finding the on board diagnostics are functioning properly with no diagnostic trouble codes displayed. The Typical Scan Tool Data Values are an average of displayed values recorded from normally operating vehicles and 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 very close.
Important: Do not use a scan tool that displays faulty data. Report the scan tool problem to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
