Scan Tool Data List - Engine Controls - 3.6L (LY7)
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The Engine Scan Tool Data List contains all engine related parameters that are available on the scan tool. The list is arranged in alphabetical order. A 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.
Use the Engine Scan Tool Data List only after the following conditions are determined:
- The Diagnostic System Check - Vehicle is completed.
- There are no diagnostic trouble codes (DTCs).
- The on-board diagnostics are functioning correctly.
Scan tool values from an engine that is operating correctly may be used for comparison with the engine you are diagnosing. The Engine Scan Tool Data List represents the values that would be seen on a normal operating engine.
NOTE:
Do not use a scan tool that displays faulty data. The scan tool concern should be reported to the manufacturer. Use of a faulty scan tool may result in misdiagnosis and unnecessary parts replacement.
Only the parameters listed below are referenced in this service information for use in diagnosis. If all values are within the typical range described below, refer to SYMPTOMS - ENGINE CONTROLS .
The column labeled Data List indicates where a parameter is located on the scan tool. Review the scan tool operating manual for the exact locations of the data lists. The following is a description of each term listed:
