data list in order to group certain related parameters
together.
Use the Engine Scan Tool Data List only after the
following conditions are determined:
• The Diagnostic System Check - Vehicle is completed.
• There are no diagnostic trouble codes (DTCs).

Description
Scan tool values from an engine that is operating
correctly may be used for comparison with the engine
you are diagnosing. The Engine Scan Tool Data List
represents the values that would be seen on a normal
operating engine.
NOTE
Do not use a scan tool that displays faulty
data. The scan tool concern should be
reported to the manufacturer. Use of a faulty
scan tool may result in misdiagnosis and
unnecessary parts replacement.
