DESCRIPTION

Input Logic:

The electrical load inputs are used by idle speed control strategy to prevent idle speed fluctuations when loads are demanded or turned off by the driver. Four circuits are used by the processor to detect the ON and OFF status of the blower motor and daytime running lights (Canadian vehicles), the headlights and the rear window defroster.
