Starter Signal: Description and Operation
CIRCUIT DESCRIPTION
When the engine is cranked, the intake air flow is slow, so fuel vaporization is poor. A rich mixture is there fore necessary in order to achieve
good startability. While the engine si being cranked, the battery positive voltage is applied to terminal STA of the ECM. The starter signal is
mainly used to increase the fuel injection volume for the starting injection control and after-start injection control.
