TYPICAL SCAN DATA VALUES
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 that the on–board diagnostics are functioning
properly. Tech 2 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 Tech 2 that displays faulty data should not be
used, and the problem should be reported to the Tech 2
manufacturer. Use of a faulty Tech 2 can result in
misdiagnosis and unnecessary replacement of parts.
Only the parameters listed below are referred to in this
service manual for use in diagnosis. For further
information on using the Tech 2 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, for diagnosis, refer to the Symptoms
section.
