       Обеспечьте выключение зажигания, ручной тормоз, положение "Р" для АKKП.
1. Соедините подходящим проводом контакты диагностического разъема "TEN" и"GND".(не допуститe электрическое соединение с контактом "B+").
2. Включите зажигание, но двигатель не заводите и наблюдайте за индикатором "CHECK ENGINE" или "MIL" ("Malfunction Indicator Light").
3. Считайте код(ы) неисправности, обращая внимание на длительность вспышек и пауз.

        Первыми высвечиваются коды с меньшим числом. Пауза между кодами - 4 сек. Длительность импульсов определяющих разряд десятков больше длительности импульсов разряда единиц. Т.е. первым "индицируются" количество десятков, следующим количество единиц, например - "Fuel pump relay"(код "51") - это 5 вспышки большей длительности и 1 вспышкa меньшей длительности.
        Выключите зажигание, удалите перемычку. Сравните с таблицей. Для достоверной диагностики после очистки памяти рекомендуется контрольная поездка и повторное считывание.
       Для автомобилей без индикатора "CHECK ENGINE", или "MIL" можно использовать стрелочный вольтметр или светодиодный индикатор. Присоедините его положительный контакт с "+" аккумулятора, контакт "-" с контактом "FEN" диагностического разъема и проведите ранее описанную процедуру считывания. Отсутствие импульсов - признак отсутствия кодов самодиагностики (DTC).

*The VRIS valves are manifold-effective-length altering butterfly valves that are used to tune the length of the intake tract to maximize ram-effect tuning and thus torque. The PCME activates these valves at present RPM values if the TPS setting is high enough.There are two valves. The #1 set is located the the left side (viewed from the radiator) and the #2 set is located nearer the throttle body. The solenoid for both valves are located at the firewall side of the intake plenum and you can see them just poking out from behind it. The #1 solenoid is the one on the left as viewed from the radiator.
The VRIS #1 solenoid sensor has a 2-position connector.

**The ECTF (engine coolant temperature - fan) sensor is used by the PCM in 1993 models to determine when it is necessary to turn on the radiator cooling fans. In 1994, the ECT (see code 9) was used to make the same determination, saving the expense of one sensor and its wiring.

       После того как коды считаны и неисправность устранена, проведите стирание кодов и повторное считывание.

Cтирание кодов:

1. Отсоедините "минусовую" клемму аккумулятора и удерживайте педаль тормоза нажатой в течение по крайней мере 10-30 секунд. Восстановите подключение.
2. "Заземлите" соответствующий тестовый контакт. Включите зажигание, но не запускайте двигатель в течении 6-10 секунд.
3. После заведения необходимо чтобы двигатель проработал при 2000 ОБ/МИН в течение 2 минут.
4. Убедитесь в отсутствии свечения индикатора CHECK ENGINE после заведения двигателя.
