Engine Immobiliser System (w/o Entry & Start System)
Theft Deterrent

The fuel trim is related to the feedback compensation value, not to the basic injection duration. The fuel trim consists of both the short-term and long-term fuel trim. The short-term fuel trim is fuel compensation that is used to constantly maintain the air fuel ratio at stoichiometric levels. The signal from the air fuel ratio sensor indicates whether the air fuel ratio is rich or lean compared to the stoichiometric ratio. This triggers a reduction in the fuel injection volume if the air fuel ratio is rich and an increase in the fuel injection volume if it is lean. Factors such as individual engine differences, wear over time and changes in operating environment cause short-term fuel trim to vary from the central value. The long-term fuel trim, which controls overall fuel compensation, compensates for long-term deviations in the fuel trim from the central value caused by the short-term fuel trim compensation. If both the short-term and long-term fuel trim are lean or rich beyond predetermined values, it is interpreted as a malfunction, and the ECM illuminates the MIL and sets a DTC.

1. СНИМИТЕ ЛЕВЫЙ БРЫЗГОВИК ПЕРЕДНЕГО КРЫЛА В СБОРЕ. Снимите 3 болта и винт. Поверните зажим, указанный стрелкой на иллюстрации, чтобы снять брызговик крыла. 2. СНИМИТЕ ПРАВЫЙ БРЫЗГОВИК ПЕРЕДНЕГО КРЫЛА В СБОРЕ. УКАЗАНИЕ: Используйте те же процедуры, что и для левой стороны.

Diesel Clean Advanced Technology (TOYOTA D-CAT) comprehensively regulates engine control (consists of a catalytic system and a fuel injection system) that purifies both particulate matter (PM) and nitrogen oxides (NOx) discharged by diesel engines. The catalytic system purifies hydrocarbons (HC) and carbon monoxides (CO), and reduces PM and NOx with a catalytic converter with the Diesel Particulate-NOx Reduction system (DPNR)

ОТСОЕДИНИТЕ КАБЕЛЬ ОТ ОТРИЦАТЕЛЬНОЙ КЛЕММЫ АККУМУЛЯТОРА. Подождите не менее 90 секунд после отсоединения кабеля от отрицательной (-) клеммы аккумуляторной батареи, чтобы предотвратить срабатывание подушки безопасности и преднатяжителя ремня безопасности.

Отсоедините 4 зажима и снимите кожух двигателя. Отсоедините разъем форсунки. Измерьте сопротивление.

REPAIR INTAKE VALVE SEAT NOTICE: Keep the lip free from foreign matter. If the seating is too high on the valve face, use 30° and 45° cutters to correct the seat.
