The Engine Scan Tool Data List contains all engine related parameters that are available on the scan tool.
A given parameter may appear in any one of the data lists, and in some cases may appear more than once, or in more than one data list in order to group certain related parameters together. Use the Engine Scan Tool Data List only after the following is determined:
• The Engine Controls - Diagnostic System Check is completed.
• On-board diagnostics are functioning properly.
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 normal running engine.
Only the parameters listed below are referenced in this service manual for use in diagnosis.
