... Technical Service Training Center Actuator Fig 2-7 illustrates example measurement of fuel injection waveform for a voltage drive type low resistance injection Fig 2-8 illustrates measurement... shows battery voltage when ECM transistor is at off state, but waveform on the figure will be observed by effect of external resistance when transistor is on When transistor shifts to 'on', injector... ECM's injector drive transistor is on and transmit injection signal, the waveform will be 'on'(grounded) and almost continuously remain 'on' In addition when ECM turns off the transistor, solenoid
