Насос подключен через реле, управляется мозгами двигателя
ENGINE-ECU.
Сработало зажигание, двигатель запустился -
насос работает.
Насос должен отключатся если срабатывают подушки\шторки (авария).
When current flows through the fuel pump relay, the relay turns ON and the fuel pump is driven. The fuel pump relay is built into the ETACS-ECU. When the ignition switch-ST signal is input, engine-ECU turns ON the power transistor for control of the fuel pump relay. As a result, power is supplied to the fuel pump. Also, if engine speed falls below a set value, the fuel pump relay is turned OFF. Thus, it deals with sudden stoppages such as engine stalling etc. by stopping the pump.
