Scan Tool Data List 3.6L

Use the scan tool data list under the following conditions:

    • The Diagnostic System Check is complete.
    • The on-board diagnostics are functioning properly.
    • No DTCs are present.

The values below 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 below 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 below were recorded under the following conditions:

    • Engine at Idle
    • Upper radiator hose hot
    • Closed throttle
    • Transmission in PARK
    • Closed Loop operation
    • Accessories OFF
    • Brake pedal not applied
