Engine Scan Tool Data List
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 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:
| • | Powertrain On-Board Diagnostic System Check is completed. |
| • | No Diagnostic Trouble Codes (DTCs). |
| • | 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 Scan Tool Data List represents values that would be seen on a normally 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.
Only the parameters listed below are referenced in this service manual for use in diagnosis. For further information on using the scan tool to diagnose the PCM and related sensors, refer to the applicable reference section listed below. If all values are within the typical range described below, refer to service category Symptoms for diagnosis.
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 data lists indicated below. |
| • | Eng 1 = Engine 1 Data List |
| • | Eng 2 = Engine 2 Data List |
| • | FF = Freeze Frame Data List |
| • | FR = Failure Records Data List |
| • | Misfire = Misfire Data List |
| • | FT = Fuel Trim Data List |
