The engine Scan Tool Data List contains all engine related parameters that are available on the scan tool. The list is arranged in alphabetical order. The parameters in the Typical Scan Data values column represent values that would be seen on a normally running engine.
IMPORTANT: 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 below are referred to in this service manual for use in diagnosis. For further information on using the scan tool to diagnose the ECM and related sensors, refer to the applicable reference section listed below. If all values are within the typical range described below, refer to Symptoms - Computers and Control Systems Symptom Related Diagnostic Procedures. The Typical Scan Data Values table contains all the parameters included in the following data lists arranged in alphabetical order:
