Engine Control Module Scan Tool Information (LU3)
The Engine Control Module (ECM) Scan Tool Data List contains all ECM related parameters that are available on the scan tool. The list is arranged 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.
Use the Engine Scan Tool Data List only after the following is determined:
* The Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) is completed
* No diagnostic trouble codes (DTCs)
* On-board diagnostics are functioning properly
The Engine Scan Tool Data List represents values that would be seen on a normally running engine under the conditions listed below.
Note: A scan tool that displays faulty data should not be used. The scan tool concern should be reported to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
If all values are within the typical range described below, refer to Symptoms - Engine Controls (Symptoms - Engine Controls) for diagnosis.
