Transmission Scan Tool Data:

TYPICAL SCAN DATA VALUES
If after completing the On-Board Diagnostic (OBD) system check and finding the Tech 1 diagnostics functioning properly and no Diagnostic Trouble Codes (DTC's) displayed. The Tech 1 Data Values are an average of display values recorded from normally operating vehicles and are intended to represent what a normally functioning system would display. The values you get may very due to low battery charge or other reasons, but they should be very close.

NOTE: A scan tool that displays faulty data should not be used, and the problem should be reported to the manufacturer. the use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.

Only the parameters listed in the images are used for diagnosis. If a scan tool displays other parameters, the values are not recommended by General Motors for use in diagnosis. For more description on the values and use of the Tech 1 to diagnose Vehicle Control Module (VCM-A) inputs refer to Testing and Inspection of the component being tested.. If all values are within the range illustrated, refer to Diagnosis By Symptom.
