Starter Signal: Testing and Inspection
Starter Signal Circuit
CIRCUIT DESCRIPTION
When the engine is cranked, the intake airflow 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 ECM. The starter signal is mainly
used to increase the fuel injection volume for the starting injection control and after-start injection control.
