Scan Tool Data List

Transmission Scan Tool Data List








Use the scan tool data values under these conditions:
^ The Diagnostic System Check is complete.
^ The On-Board Diagnostics are functioning properly.
^ No DTCs are present.
These values represent a typical display recorded from a properly functioning system.

Important: Do not use a scan tool that displays faulty data. Report the condition to the scan tool manufacturer. The use of a faulty scan tool can result in misdiagnosis and the unnecessary replacement of parts.

Only these parameters listed are used for diagnosing. If a scan tool displays other parameters, the values are not recommended by General Motors for use in diagnosis.
Scan tool values listed were recorded under these conditions:
^ Engine at idle
^ Upper radiator hose hot
^ Closed throttle
^ Transmission in Park
