I found a wrong connection in the relays box, i fix it and the problem finished, thanks for your comments swoop223, best regards!!

code E30
— ECCS C/U Error signal. No power supplied to the ECM or ECM detects an insufficient voltage supply.
— No or low or high supplied power to the ECM.

The most common causes :
— EGI relay 1 open or short circuit
— EGI Relay 2 open or short circuit
— Main C relay open or short circuit
— Ignition relay open or short circuit
— Open ground circuit
— Open across fuse: F6- EGI relay 1 or F7- EGI relay 2 open circuit
— Corroded or broken wires at the ECM or lower left side step plate relay box and body ground.
— Internal open or short in the ECM
— Abnormally low or high ECM to sensor output voltage detected

From my experience the most common issue i have seen causing this issue is either a bad ground on the frame side of the truck where the grounds connect to the stud on the side of the frame under the battery. Remove the cables and wires and make sure there is no paint on the surface where the wire connectors make connection, if there is scrape the paint away and then reconnect the wires.
Secondly mcfa had issues with the relays on these units and had to do a parts update on the relays, the old ones were black and were updated to a green colored one. Intermittant signal from these relays can cause the EGI circuit to trigger a code.
If you find it still has the black ones in it replace them. It mentions above checking the black relay box under the foot step on the left side, i have rarely had to deal with these relays so that would only be a step to take if you do not find any problem with the other relays.

Also check the fuses in the fuse box and make sure none are blown, since this code indicates an open circuit in the EGI circuit it could just be a blown fuse. (uncommon)

«Болезни»:

За несколько лет работы с данными двигателями выработался определенный опыт.

Вот основные уязвимые места в двигателе:

1.  Неисправность датчика MAF, в простонародье – «расходомера воздуха»

2. Потеря давления в топливном насосе

3. Неисправность катушек зажигания

4. Плохой запуск или его отсутствие из-за неисправности стартера

5. Потеря мощности из-за «срыва» катализаторов (фото 30 — 33)

6. Постоянная детонация и повышенный расход топлива из-за большого количества сажи на  клапанах (засаженность)

7. Нарушение фазы газораспределения

8. Неправильная работа инжекторов

Наверное, самая распространенная жалоба клиентов при посещении сервиса – горящий CHECK ENGINE

Горящий Check Engine
и, иногда, временное, а иногда  постоянное «троение» двигателя. Как следствие — потеря мощности;  как правило, это связано с нарушениями в системе зажигания. Блок управления оценивает работу катушек зажигания и при малейшем нарушении  информирует водителя о проблеме (зажиганием лампы CHECK ENGINE).

При сканировании выявляется код Р1320 — сигнал системы зажигания, «первичная сторона».

Про эту проблему уже писали на страницах данного форума.

Хочу лишь добавить свою методику проверки неисправной катушки зажигания. На левой головке двигателя доступ к катушкам зажигания открыт и здесь совсем не составляет труда осциллографом проверить импульсы на управляющих выводах катушек.  На правой же головке доступ, напротив, затруднен. Для нормальной проверки катушки  приходится демонтировать. Я меняю их местами с разных «головок» для проверки. Делаю это для того, что бы визуально проверить состояние наконечников. Нередки случаи пробоев и «зеленения» контактов из-за воды или масла.

Важно проверить катушку на разряднике — на неисправной катушке будут видны явные пропуски искрообразования.

Вот несколько осциллограмм:

ФОТО 7 — правильная работа

ФОТО 8 —  катушка в «обрыве» (силовой транзистор или обмотка)

ФОТО 9  и 10 — неправильная работа силового транзистора в катушке.

При проверке нужно обращать внимание и на наличие масла в свечных колодцах (оно туда может попадать через «задубевший» сальник клапанной крышки). При наличии масла есть вероятность «пробоя»  катушки либо коммутатора в ней.

Следующая проблема связана с отказом или нарушением правильной работы датчика MAF — датчик массового расхода воздуха.

При работе двигатель потребляет огромное количество воздуха и качество его фильтрования влияет коренным образом на работу данного датчика. В расходомере производители применили открытый кристалл. При постоянном воздействии частиц пыли на кристалл он мутнеет (от постоянного «пескоструя») или просто забивается грязью и, как результат, параметры датчика «уходят в сторону».  Нормальная работа двигателя становится невозможной. Диагностика данного девайса очень проста – замеряем напряжение при включенном зажигании на сигнальном выводе датчика  и сравниваем с нормативными показателями (1,03- 1,05 вольта).

Показания  завышены:

При отклонениях в параметрах меняем датчик на исправный.

При неисправном датчике (внутренний обрыв) на сканере «застынет» показание в 1,01-1,04вольт, и оно не будет меняться при перегазовках. При обрыве проводки к датчику
— показания на мониторе сканера будут нулевыми.

В Интернете бытует мнение о возможности промывания в спирте загрязнённой части датчика. Мне несколько раз приходилось мыть датчик, но к положительному результату эта процедура не приводила.

Если же параметры датчика заметно «уплыли» (на хх 1,5 — 1,7 в), то временно восстановить работу двигателя можно изменив количество проходящего через него воздуха. Для этого нужно лишь на 10 — 15 градусов повернуть датчик по часовой стрелке. Болты крепления, конечно, нужно демонтировать.

Фото 18
фото 18

Более серьезная проблема – это износ ТНВД. При пониженном давлении двигатель способен работать, но наблюдается заметный черный выхлоп, «троение», потеря мощности и очень большой расход топлива. Регистрировать давление очень просто. На сканер выводится строчка с параметром с датчика давления, установленного на насосе. Давление изменяется соразмерно оборотам двигателя.

Фото 19
фото 19

Правильное давление — 6,8-7,4МРа на хх.

Если нет сканера, то можно проконтролировать давление с помощью вольтметра на разъёме датчика давления. Разъем датчика расположен в доступном месте и проделать эту процедуру не составит труда.

можно посмотреть зависимость напряжения от давления.

(Р1232) high pressure regulator — регулятор высокого давления
то Вам, как диагносту, следует сделать некоторые замеры. Вы должны проверить наличие управляющего импульса на клапане ТНВД и проверить, какое давление развивает подкачивающий насос в топливном баке.

Это необходимо делать, чтобы исключить неправильный диагноз по замене насоса и не стать впоследствии «счастливым его обладателем». Не исключается  вероятность того, что при заклинивании насоса «срезало» привод ТНВД и «просто замена» не решит проблему, а время будет потеряно для Вас и для Клиента.

Часто при разборе насосов видны следы износа плунжеров, подшипников, разрыва гофры, заклинивание плунжеров. Основными  виновниками выхода из строя насоса являются вода, грязь, песок,  которых предостаточно в нашем «чистом» отечественном топливе.

А здесь «разбитый» подшипник в насосе деформировал «гофру» из-за деформированного сальника на приводе (вытекло масло из насоса и произошёл перегрев подшипника)

При снятии ТНВД обращайте внимание на направляющие втулки — их две. Они легко могут скатиться в полость головки, что приведет к непредсказуемым последствиям.

Следует отметить, что в новом насосе нужно обязательно проверить наличие масла,  без которого насос не проработает и несколько часов.

Многие проблемы на данных двигателях пересекаются. Одна является следствием другой. При проблемах в системе зажигания и отказах в работе катушек, несгоревший бензин догорает в катализаторах. Температура катализатора увеличивается до немыслимых значений. Коллектор накаляется докрасна, появляется вероятность возгорания автомобиля. На «Цедриках» и «Глориях» установлены три катализатора. Два непосредственно рядом с головками (они металлические) и один керамический под днищем автомобиля.

Катализаторы нередко срывает со штатного места и ими, буквально, выпускной тракт «запаковывается» как пробкой. Теряется мощность двигателя.

Проконтролировать «забитость» можно при помощи датчика давления. Доступ к датчикам кислорода ограничен. Порт датчика давления подключается в отверстия лямбда-зондов. При диагностике «пытайте» Клиента — сколько времени он катается на «троящем» двигателе.

Фото 32

Фото 33

При работе на ХХ следует обращать внимание на температуру патрубков системы EGR. Были случаи, когда металлические частицы прогоревшего катализатора попадали под шток клапана, тем самым не давая ему закрыться.

Как результат — неровная работа двигателя и раскаленная  подводная трубка.

Фото 34
фото 34

Еще одна серьезная проблема — это так называемая «засаженность» двигателя. Коллектор двигателя с прямым впрыском — он большого обьема. По моему мнению, это обусловлено необходимостью улавливания частиц сажи, оставшихся после полного сгорания смеси. Сажи накапливается огромное количество. В практике встречались автомобили с практически полностью перекрытыми клапанными каналами. Чистку коллектора следует производить при возникновении постоянной детонации при работе двигателя. Увидеть сажу можно просто при осмотре форсунки холодного пуска.

Очистка, как правило, не занимает много времени, так как кокс и сажа практически всегда имеют «сухую» структуру. Весь этот налет легко снимается скребками и всевозможными ёршиками. С чисткой коллектора не возникнет трудностей, а вот с клапанами придется повозиться. Ставим поршень цилиндра в ВМТ и счищаем сажу на днище клапана. Затем удаляем сажу пылесосом. Так все 12 отверстий.

Остатки выдуваем сжатым воздухом. Если вам «не повезло» и колпачки «текут», то кокс будет сырой — здесь придется воспользоваться очистителями. А собирать  растворённую грязь либо шприцем, либо «отсосом».

Блок управления постоянно фиксирует код ошибки.

Замена датчика не решает проблемы.

Импульс имеется, а запуска не происходит.

 Проблема лежит глубже.

Этот «трабл» не раз обсуждался на нашем форуме, я просто повторю то, что уже писалось и добавлю из своего опыта.

Вся проблема  заключается в «неровной работе стартера», «просадке» напряжения, разбитые втулки или изогнутый маховик, налипание частиц металла к датчику.  Это приводит к тому, что начальный импульс датчика коленвала становится неправильным.

Фото 45
фото 45

(…на нашем форуме диагност из города Санкт-Петергбурга Vasaby   так писал про эту проблему:

«Прикол в том, что электрические помехи от стартера тут ни при чем. Минусовой провод батарея-мотор можно поставить удлиненный, проложить мимо датчика и увести на болт крепления стартером. И все равно запуск станет легче. Дело в чувствительности датчика скорости вращения колена к большим угловым ускорениям-замедлениям венца при подклинивании якоря стартера или рывкам колена вблизи ВМТ из-за недостаточной мощности стартера».

Проблема решается либо заменой стартера, либо переносом дополнительного минусового провода на болт крепления стартера…).

Регистрировать  данную проблему можно, наблюдая за параметром  POS COUNT в «дате» сканера его значение должно быть 180

Можно просматривать импульс с датчика коленвала.

Чем меньше участок с «грязным» импульсом, тем быстрее произойдет запуск.

Есть еще одна проблема с затруднённым запуском – DTC P1335.

REF sensor – датчк КВ 120 град и ВМТ

Отсутствие сигнала с датчика коленвала (переднего) также нарушает процесс синхронизации. При отсутствии этого сигнала двигатель все же запускается, но с трудом (долгое вращение стартера)

Правильный сигнал

И сам датчик

Одна интересная деталь — ВМТ это всегда  REF двойной импульс, PHASE 3 импульса — 1 цилиндр, 4 импульса — 4 цилиндр.

Одна интересная деталь – ВМТ.
Так можно проверить метки цепи не снимая крышки на  двухканальном осциллографе. Так как датчики индуктивные, то можно вообще зажигание не включать (со снятыми коллекторами) просто подав «+» на стартер.

Синхронизация_ REF двойной импульс и PHASE 4 импульса — 4 цилиндр.

Синхронизация  ВМТ и катушки 1 цилиндра

IGN — это положение импульса на катушку 1 го цилиндра и REF

IGN - это положение импульса на катушку 1 го цилиндра и REF.

На данных двигателях  установлены низкоомные инжекторы, способные работать на обычном и на очень большом давлении, до 120кгсм2. Управляющий импульс вырабатывается специальным блоком — усилителем инжекторов. Усилитель вырабатывает импульс амплитудой до 100 вольт, который способен открыть и закрыть инжектор под большим давлением. За время эксплуатации сопла инжекторов загрязняются, загрязняется и игла.

Тем самым нарушается нормальная работа форсунок, распыл и производительность.

Мыть форсунки следует в ультразвуке по аналогии с инжекторами от TOYOTA или MMC.

Подающая топливо «рейка» прикручивается к инжекторам специальными болтами. Для их демонтажа потребуется изготовить особый ключ.

Снимать форсунки следует с осторожностью, и использовать простейший съемник.

Демонтаж форсунки надо производить плавно и равномерно во избежание ее повреждения. Предварительно на посадочное место надо распылить смазку, например VD-40.

«Закоксованные» форсунки также приводят к обеднению смеси, потери мощности, проявлениям детонации, не устойчивому ХХ.

Бывали случаи, когда из-за грязи форсунка начинает «лить» топливо. Увеличивается общий расход топлива. Заметен запах и «черный» выхлоп. Свеча зажигания  не успевает очищаться, а датчик кислорода постоянно регистрирует «богатую» смесь. Такую форсунку редко удается «оживить».

Работу инжекторов можно наблюдать осциллографом прямо на усилителе инжекторов.

При изменении в сопротивлении обмотки инжектора фиксируется код  неисправности P1216 injector D/U., эта ошибка может указывать и на отказ усилителя.

Следующая проблема связана с нарушением  фаз газораспределения.

Блок управления двигателем фиксирует шесть кодов,  связанных с данной проблемой. На распредвале установлена шестерня, способная изменять его положение  в зависимости от давления подводимого к ней масла. В этой системе есть четыре ключевых элемента – клапан, муфта с шестерней, датчик положения муфты, датчик распредвала

При нарушении в работе клапана (клапанов) блок управления фиксирует ошибку

DTC P1111, P1136 IVT control solenoid valve.

Эти коды указывают на электрические проблемы в управляющих клапанах (следует проверить сопротивление, наличие управляющего сигнала, питание). Сопротивление клапана 7,0 -7,7ом при температуре 20 градусов Цельсия.

При отсутствии импульса с датчиков положения муфты, ECM регистрирует ошибки

DTC P1140, P1145 IVT control position sensor.

Следует проверить импульсы на датчиках и наличие питания. Если смотреть на двигатель, то код P1140 указывает на неисправный левый датчик, а код P1145 на правый.

Правильный импульс

При невозможности установки заданного положения распредвала и при наличии импульсов с датчиков фазы фиксируются коды 

DTC P 1110, P1135.  INTAKE VALVE TIMING CONTROL PERFORMANCE

При возникновении этих кодов следует  проверить гидравлическую часть системы, подклинивание клапана, грязь в сетке, неисправность самой гидравлической муфты.

Форму сигналов можно посмотреть по ссылке

И напоследок небольшая хитрость по снятию и установке необычных разъемов на датчиках.

Под пружинки механизма попадает грязь, из-за чего разъеденить разъем очень сложно. Чтобы не сломать эту конструкцию, нужно брызнуть проникающей смазкой в место хода защелки и вся конструкция вновь заработает.

Я попытался  максимально коротко осветить наиболее часто встречающиеся проблемы с данной серией двигателей. Всем удачных ремонтов и добрых клиентов.

How to clear forklift error codes

How to clear forklift error codes?

In all new generation of forklift and also some old models of forklift sometimes when you are using the forklift will see some error code on the monitor(dashboard) of the forklift.
In different forklift, each Error code means different things.
On Yale and Hyster forklift the error code can be showed or can be in the system.

 Yale and Hyster Forklift Fault Codes List 

Yale and Hyster error codes

How to going inside the system to clear the error codes?

for going inside the system you need the password that the company using or can be changed by the dealer before they ship it to the customer.
When you go inside the system you are able to see the error code and you will see how many time this error code showed in your forklift and also when (In witch hours of using the forklift), from the error code list that the company gives for each forklift to the dealers and forklift technician you will understand what is the problem and you can solve the issue with any headache.
In some other trucks same as Raymond, Toyota, and Nissan you will see the error code directly in the forklift and you can solve the issue and use the forklift easy.
 

How to detect and figure out forklift error codes?

In all forklift when the technician connect with computer to forklift all the issue and error will show up and he can fix for you, your forklift
Sometimes you see the error code in your forklift but you see your forklift work well, But it can be a point and you have to solve it because it is same as alarm and if you don’t ask the forklift technician for this issue in future you will be stuck with the bigger problem and big charge to repair your forklift.
Our suggestion is when you do your daily checklist please look and see your forklift doesn’t have any error code.
If you find any error code, don’t use the forklift to solve the issue.
 

How you can figure out forklift error codes?

Please leave the error code below this article then We and other specialists will answer you as soon as possible.
