! Ошибки OBD2 - Обсуждение и решение проблем.

[Richmond 98]

Достаточно часто в клубном чате, на форуме и в личке на drive2 спрашивают по той или иной ошибке и что с этим делать. 

В этой связи, решил создать 1 общую тему,  где будут ссылки на номера ошибок и описание, а в обсуждении будем рассматривать и подсказывать как победить поломку)

Что такое OBD ? OBD (On-Board Diagnostic) systems - Идентификатор параметра, используемый для запроса диагностической информации автомобилей. Стандарт SAE J1979 определяет стандартный список таких кодов, но производители вправе добавлять свои специфические коды. Также производители могут использовать не все коды, регламентированные стандартном SAE J1979.

 

Системы OBD встречаются в большинстве транспортных средств, используемых сегодня. OBD - это электронная система, предназначенная для управления функциями двигателя и диагностики проблем двигателя или отказов компонентов, а также минимизации выбросов. OBD-II, новый стандарт, введенный в автомобили, выпущенные после 1 января 1996 года, обеспечивает практически полное управление двигателем, а также контролирует детали шасси, кузова и вспомогательных компонентов, а также сеть диагностического контроля автомобиля.

Автомобили, оснащенные OBD-II, имеют разъем, расположенный в пассажирском салоне, обычно доступный с места водителя (под приборной панелью над рычагом открывания капота в Grand Cherokee WJ). Кабель подключен к разъему OBD-II и подключен к сканирующему инструменту. Это может варьироваться от простого ручного счетчика, который обеспечивает кодированное считывание различных диагностических функций, до большого консольного компьютерного устройства стоимостью в тысячи долларов.

Коды неисправностей обычно появляются после того, как загорелся индикатор «Check engine». Данные, предоставляемые системой OBD-II, могут иногда точно определять неисправность конкретного компонента, экономя существенное время и стоимость обслуживания. Сканирование сигналов OBD-II также может предоставить важную информацию при покупке подержанного автомобиля. Недавнее внедрение менее дорогих сканирующих устройств позволило домашним механикам и небольшим магазинам получить доступ к сигналам OBD-II, чтобы использовать их для собственных испытаний и ремонта.

 

Malfunction Indicator Lamp (MIL) (Индикаторная лампа неисправности (MIL))

 

В Grand Cherokee WJ MIL дает указание оператору транспортного средства, когда модуль управления силовым агрегатом (PCM) записал код неисправности диагностики (DTC) для неисправности цепи или неисправности, связанной с выбросами бортовой системы диагностики II (OBDII). MIL управляется транзистором на печатной плате комбинации приборов на основе программирования кластера и электронных сообщений, полученных кластером от PCM по шине данных интерфейса программируемой связи (PCI).

Лампа MIL полностью контролируется логической схемой комбинации приборов, и эта логика позволяет этому индикатору работать только тогда, когда комбинация приборов получает ток от аккумулятора на выходной цепи плавкого выключателя зажигания. Поэтому лампа всегда будет выключена, когда ключ зажигания находится в любом положении, кроме «Вкл» или «Пуск». Лампа горит только тогда, когда транзистор комбинации приборов обеспечивает путь к земле.

Комбинация приборов включит MIL по следующим причинам:

ИСПЫТАНИЕ НА ЛАМПУ - Каждый раз, когда ключ зажигания поворачивается в положение «Вкл.», Индикатор MIL горит в течение примерно трех секунд в качестве теста лампы.

MIL LAMP-ON MESSAGE - Каждый раз, когда кластер получает сообщение PCM о включении лампы MIL, индикатор загорается. Индикатор может включаться и выключаться или светиться непрерывно, как указано в сообщении PCM. Для некоторых кодов неисправности, если проблема не повторяется, PCM автоматически отправит сообщение о выключении лампы. Другие коды неисправности могут потребовать устранения неисправности и сброса PCM перед отправкой сообщения об отключении лампы.

ОШИБКА СВЯЗИ - Если кластер не получает сообщений о включении или выключении лампы от PCM в течение двадцати последовательных секунд, MIL подсвечивается комбинацией приборов. Индикатор остается управляемым и освещенным кластером до тех пор, пока от PCM не будет получено действительное сообщение о включении или выключении лампы.

МИЛ освещение

Во многих случаях системы выбросов должны проходить диагностические тесты более одного раза, прежде чем PCM высветит MIL. Эти тесты известны как «два монитора поездки». Другие тесты, которые включают лампу MIL после одного сбоя, называются «мониторами с однократным отключением». Поездка определяется как «завести автомобиль и эксплуатировать его в соответствии с критериями, необходимыми для работы данного монитора».

Определенные условия, такие как незакрепленная или отсутствующая газовая крышка, плохое качество топлива и т. Д., Могут загореться после запуска двигателя. Автомобиль следует обслуживать, если свет продолжает гореть в течение нескольких типичных циклов движения. В большинстве случаев автомобиль будет двигаться в обычном режиме и не потребует буксировки.

Длительное вождение с включенной лампочкой «Индикатор неисправности» или «Проверить двигатель» может привести к дальнейшему повреждению системы контроля выбросов. Это также может повлиять на экономию топлива и управляемость. Транспортное средство должно быть отремонтировано до проведения любого испытания на выбросы.

Если индикатор мигает, это может привести к серьезным повреждениям каталитического нейтрализатора и потере мощности. Требуется немедленное обслуживание.

 

Ну это немного теории, ниже пишите, делитесь своими ошибками и как вы их исправляли!

Follow all appropriate diagnostics for the fault that is present. Prior to replacing parts, check all connectors between the speed control switch and the PCM for moisture Internally the PCM uses the same A/D (analog to digital) converter for TPS voltage as it does for the speed control switch sense. If the v-37 circuit has voltage bleed over from another source, a code of TPS Shorted to voltage may be set in the PCM. The DN model equipped with rear heat option, has an external water pump to circulate coolant to the rear heater. If you find coolant in the bulkhead connector, the likely cause would be a leaking coolant pump. Pump should be replaced if found leaking. If the code sets when the A/C is turned on go right to the bulk head connector and check for moisture. Check for a shorted clock spring causing the speed control 5 volt feed to be shorted to power.

If after performing all powertrain test for P0441 with results that appear to be normal/test pass, check for fuel in the purge canister. If there is fuel in the purge canister check ORVR (on-board refueling vapor recovery) system per service manual section 25. If ORVO is working as designed insure that the vehicle owner is not overfilling the fuel tank.
P0442 (M)	Evaporative Emission Control System Leak Detected (medium leak)	A 0.040 leak has been detected in the evaporative system. (A faulty gas cap may cause this code). Also see TSB 25-001-02A. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.

P0455 (M)	Evaporative Emission Control System Leak Detected (large leak)	A large leak has been detected in the evaporative system. See TSB 25-001-02. Also, possible faulty or loose gas cap. Note: The respective Powertrain Diagnostic Procedures Manual will direct the technician to determine if the vehicle evaporative system has an external system leak. Examples of some external system leaks are: a loose gas cap, a disconnected evaporative system hose, or a loose hose connection. Remember that the evaporative system may also have an internal system leak. This internal leak may be caused by an intermittent or permanently stuck open Duty Cycle Purge (DCP) valve. This leak source is considered to be internal because any escaping emissions enter into the engine system and not directly into the atmosphere, unlike an external leak. An internal leak may cause one of the above DTC?s. Possible causes of a stuck open (intermittent or permanent) DCP valve are: 1. Corrosion due to system moisture or possible water intrusion into the system.
P0456 (M)	Evaporative Emission Control System Leak Detected (very small leak)	A 0.020 leak has been detected in the evaporative system. See TSB's 25-001-02A, 18-002-03 and 25-004-01. Also, possible faulty or loose gas cap. (Also see Notes in P0455 above). Does customer regularly commute on a steep grade (down hill grades in excess of 10%? Has the Leak Detection Pump Operation and Diagnosis booklet (Publication No. 81-170-000606) been used to assist in the diagnosis? Review and if necessary, perform TSB 18-010-02. Be sure to completely read the TSB. The fix for the condition is a PCM replacement, not a reprogramming of the controller. Be sure that there is not any leaks in the system. This TSB applies in a very limited number of cases and usually in mountainous regions. TSB 18-010-02 Is a PCM replacement correct an erroneous MIL illumination for SAE P0456 that sets when driven on steep grades.

This may occur after driving the vehicle in rain or by washing the vehicle. Also if the rear heater water pump is leaking, as on a DN model with rear heat, the C200 could be contaminated with anti-freeze. Once connector is cleaned from antifreeze contamination, review water pump for potential leak and repair as necessary. If there is water intrusion into the connector, dry the connector and repair area that is allowing water into the connector. This area is the source of many speed control complaints. Various fault codes can be set due to contamination of this connector.
