Typical bipolar steppers have 4 leads, connected to two isolated coils in the motor. The fast idle solenoid is not the same as an IAC motor, or anything that is controlled like a stepper motor. It is either open or closed. One example of an application for the screw-in IAC is a 1984 Corvette. Apparently some valves are fully closed at 100% PWM, others are fully closed at 0% PWM, you will have to experiment to see which way yours operates.

Required if your stepper ‘free wheels’ when you spin its pintle un-powered with your hand. 15-minute IAC: Operates the IAC is always on for 15 minutes, then switches to ‘moving only’. This is sometimes helpful if your IAC operation is erratic. These motors can be operated through ~256 ‘steps’. The GM IAC, for example, can turn up to 320 steps. Ассистент движения по полосе (rus.) Конструкция и принцип действия. The most practical place is at the 40 pin socket where you put the +12V supply. The fast idle solenoid is an off/on electrically controlled vacuum “leak” that speeds the engine RPM for cold starts. Likewise, to decrease the idle speed, the pintle is moved closer to its seat.

Если вы не нашли информацию по своему автомобилю — посмотрите ее на автомобили построенные на платформе вашего авто. С большой долей вероятности информация по ремонту и обслуживанию подойдет и для Вашего авто. However setting it to «IAC Stepper Moving Only», might cause a problem with idle speed changing from one start to another. Each pulse results in specific amount of rotation of the motor . The motor can be made to spin either direction by changing the polarity of the pulses. On GM IAC steppers, the one coil usually has blue wires leading to it, the other coil has green wires. This is very likely to be the problem for those who see the proper step commands given in software but inconsistent response from the motor, such as requiring a restart to lower the hot rpm after a cold start.
