Typical Scan Data Values

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 are referred 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 . If all values are within the typical range described, refer to the Symptoms section for diagnosis.
