For 1990-2009 cars

This Typical Scan Tool Data Values table contains all transmission related parameters that are available on the scan tool. The list is in alphabetical order. A given parameter may appear in any one of the data lists, and in some cases may appear more than once, or in more than one data list in order to group certain related parameters together. The Engine and Misfire data list, typical values and data definitions are covered in Engine Controls.

Use the Typical Scan Tool Data Values table only after the following is determined:

• | Powertrain or Transmission On-Board Diagnostic System Check is completed.

• | No Diagnostic Trouble Codes (DTCs) are set.

• | The on-board diagnostics are functioning properly.

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

Scan tool values from a properly operating vehicle may be used for comparison with the vehicle you are diagnosing. The Typical Scan Tool Data Values table represents values that would be seen on a normally operating vehicle.

Only the parameters listed below are in this service manual for use in diagnosis. For further information on using the scan tool in order to diagnose the TCM and related components, refer to the applicable reference section listed below. If all values are within the typical range described below, refer to Symptoms in Engine Controls for diagnosis.

Scan values are performed under the following conditions:

• | Engine at idle

• | Upper radiator hose is hot

• | Closed throttle

• | Transmission in Park

• | Closed loop operation

• | Accessories OFF

• | Brake pedal not applied
