Scan Tool Data List Except Holden
The Engine Control Module 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 Control Module Scan Tool Data List only after the following is determined:
| • | The Diagnostic System Check - Vehicle is completed. |
| • | No diagnostic trouble codes (DTCs) are present. |
| • | The on-board diagnostics are functioning properly. |
Scan tool values from a properly running engine may be used for comparison with the engine you are diagnosing. The Engine Control Module Scan Tool Data List represents values that would be seen on a normal running engine.
Important: A scan tool that displays faulty data should not be used. The scan tool problem should be reported to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
The column labeled Data List indicates where a parameter can be located on the scan tool. Refer to the scan tool operating manual for the exact locations of the data lists. The following is a description of each term listed:
All: The parameter is in all of the data lists indicated below.Eng: Engine Data List
CH: Cooling/HVAC Data List
CC: Cruise Control Data List
EGR: Exhaust Gas Recirculation (EGR) Data List
