Scan Tool Data List: Overview

DESCRIPTION
Use the TYPICAL SCAN DATA VALUES table only after the On-Board Diagnostic System Check has been completed, no DTC(s) were noted and you have determined the on-board diagnostics are functioning properly. Testing and Inspection

Scan tool values from a properly running engine may be used for comparison with the engine you are diagnosing. The TYPICAL SCAN DATA values represent values that would be seen on a normally running engine.

NOTE: A scan tool that displays faulty data should not be used, and the problem should be reported to the scan tool manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.

Only the parameters listed in the following articles are provided from the OE manual for use in diagnosis. If all values are within the typical range described below, refer to Symptoms for diagnosis. Testing and Inspection
