Диагностический разъем предназначен для скоростного обмена данными с устройствами диагностики по одному из трех специальных протоколов обмена данными. Данный способ позволяет считывать коды ошибок и стирать их, корректировать некоторые предустановки в RAM |
Назначение контактов диагностического разъема.
Контакт 02 - J1850 Bus+
Контакт 04 - Chassis Ground
Контакт 05 - Signal Ground
Контакт 06 - CAN High (J-2284)
Контакт 07 - ISO 9141-2 K Line
Контакт 10 - J1850 Bus
Контакт 14 - CAN Low (J-2284)
Контакт 15 - ISO 9141-2 L Line
Контакт 16 - Battery Power
Протокол ISO 9141-2 идентифицируется наличием контакта 7 и отсутствием 2 и/или 10 контактов на диагностическом разъеме. Если отсутствует контакт 7, в системе используется протокол SAE J1850 VPW (Variable Pulse Width Modulation) или SAE J1850 PWM (Pulse Width Modulation). Все три протокола обмена данных работают через стандартный кабель OBD-II J1962 connector.
Контакты диагностического разъема
для используемых протоколов.
Контакты 4, 5, 7, 15, 16 -
ISO 9141-2.
Контакты 2, 4, 5, 10, 16
- J1850 PWM.
Контакты 2, 4, 5, 16 (без
10) - J1850 VPW.
При наличии критической ошибки, на приборной панели автомобиля загорается лампа "MIL", которая указывает на необходимость проведения диагностики автомобиля. При этом в памяти контроллера фиксируется пяти-значный код ошибки. Коды ошибок включают в себя три категории:
"P" - is for powertrain codes;
"B" - is for body codes;
"C" - is for chassis codes.
Категория
указывается в первой
позиции пяти-значного
кода ошибки. Вторая
позиция в этом коде говорит о стандарте, где "0"
- общий для OBD-II код или "1"
- если код производителя.
Третья
позиция идентифицирует тип неисправности:
"1"
и "2" - неисправности в топливной системе
и/или воздухоподачи;
"3" - проблемы в системе зажигания;
"4" - для вспомогательного контроля
эмиссии;
"5" - проблемы холостого хода;
"6" - неисправности контроллера
и/или его выходных цепей;
"7"
и "8" - неисправности трансмиссии.
Четвертая
и пятая позиции
пяти-значного
кода ошибки указывают непосредственно на саму ошибку.
