Cranking Signal: Description and Operation
PURPOSE / OPERATION
When the engine is cranked, the intake air flow is slow, so fuel vaporization is poor. A rich mixture is therefore necessary in order to achieve good
startability. While the engine is being cranked, the battery positive voltage is applied to terminal STA of the Engine Control Module. The starter
signal is mainly used to increase the fuel injection volume for the starting injection control and after-start injection control.
