When the engine begins to run but it was not hot enough and the electricity load is raising, such as the time after the warm air fan switch, cooling fan relay and tail lamp switches are connected, meanwhile the cutting/offering oil injector is working asynchronously, the signals are sent to ECU in the form of switch volume or analog volume signals, and the ECU will order VSVI terminals to connect with the ground, so that the idling speed is raised, and the magnetic valve(VSV) allows some air to flow in the balance box(not through the throttle).
