Transmission Scan Tool Data List
Use the scan tool data list under the following conditions:
* The Diagnostic System Check is complete.
* The outboard diagnostics are functioning properly.
* No DTCs are present.

The 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 the parameters listed are used in this manual for diagnosing. If a scan tool displays other parameters, the values are not recommended by General Motors for use in diagnosis.

Scan tool values were recorded under the following conditions:
* Engine at Idle
* Upper radiator hose hot
* Closed throttle
