Scan Tool Testing and Procedures

Powertrain Control Module Scan Tool Information

The Powertrain Control Module Scan Tool Data List contains all engine related parameters that are available on the scan tool. The Scan Tool Data List is a master list arranged in alphabetical order.

Use the Engine Scan Tool Data List only after the following is determined:

* The Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) is completed.
* No diagnostic trouble codes (DTCs)
* On-board diagnostics are functioning properly

The scan tool values from a properly running engine may be used for comparison with the engine you are diagnosing. The Engine Scan Tool Data List represents values that would be seen on a normally running engine.

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


Only the parameters listed below are referenced in this service manual for use in diagnosis.
