Система самодиагностики MITSUBISHI
Здесь тоже имеется диагностический разъем, расположенный, как видно из рисунка, "правее правой" ноги водителя. Для осуществления самодиагностики необходимо соединить вывод "1" диагностического разъема с "массой". Считывание кодов неисправностей производится как и лампочкой CHECK на панели приборов, так и при помощи стрелочного вольтметра.
Диагностический разъем на моделях выпуска после 90-х годов
Диагностический разъем "старый"
Удаление  кодов неисправностей происходит путем отсоединения отрицательной клеммы аккумуляторной батареи более чем на 15 секунд.

(1) - MIL will illuminate on first detection of the malfunction. For
all other malfunctions, MIL will illuminate when engine is next
turned on and malfunction is again detected.
(2) - If misfire is severe enough to cause catalytic converter damage,
MIL will continuously flash as long as danger is present.
