Scan Tool Data List - Engine Controls - 3.6L (LY7)

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" for diagnosis.

Selection(s)
The engine control module (ECM) commands the generator OFF
by removing the 5-volt reference signal from the L-terminal of the
GEN L-Terminal
voltage regulator when you select OFF. The generator will then stop
generating an output voltage.
The ECM supplies 12 volts to the starter relay control circuit when
ON is selected. When OFF is selected, 12 volts is removed from the
control circuit
