Чуть больше года назад уже выскакивала ошибка U0284. Активные жалюзи радиатора тогда были куплены новые и ошибка самоликвидировалась. Как оказалась, не на всегда. Пару дней назад вновь пришла в гости, а гостья эта не из дешёвых. Прошлый раз обошлось в 200 долларов. Позвонил на своё любимое СТО и поделился проблемой. Всё по старой схеме- приезжай, разберемся. Приехал, сняли бампер, посмотрели, а контакты на разъёме окислились и почти отгнили. Думали, что перепаяв контакты проблема исчезнет. Но это было бы слишком легко. Контакты перепаяли, подключили разъём к жалюзям и ошибка U0284 ушла… Но пришла другая U0077. Сбрасываться категорически не хотела никакими сканерами и программами. Ещё раз позвонили и проверили проводку. Всё ОК. Сняли электропривод с моих жалюзей, но оставили подкюченным к питанию. На включение зажигания он никак не реагировал (а должен закрутиться механизм). Благо, что СТО большое и ремонтируют много автомобилей, привезенных с Америки. Нашли ещё два, вроде как рабочих, электопривода жалюзей. Подключили, по очереди, сначала один, а потом другой. В обоих закрутился, при включении зажигания, механизм привода жалюзей, но ошибка сама не уходила и сканером не удалялась. Мозги у всех начали потихоньку закипать. Я попросил найти третий электропривод, если есть. И он действительно нашёлся. Последний. Конечно надежда была слабой, но я не отчаивался. И как только мы подключили его к разъёму, он закрутился, как и предыдущие, но ОШИБКА ушла. Слава богу! И спасибо любимому СТО и его сотрудникам, за то, что с душой подошли к моей проблеме. Как то так. Всем мира и добра!

Описание U0284 ошибки автомобиля Subaru. В нашем справочнике имеется следующая информация:
На русском языке:
Это не часто встречающаяся неисправность в электрической цепи двигателя или автоматической коробки передач, вероятнее всего специфическая для Вашей марки автомобиля.
На английском языке:

Найти причину >>>
Принимая во внимание тот факт, что OBD2 ошибки работы электронных систем автомобиля не всегда на прямую указывают на неработающий элемент, а чаще дают всего лишь общую информацию о неисправности, мы пришли к следующему выводу:
В разных марках и моделях автомобилей одна и также ошибка может возникать как следствие неисправности абсолютно разных элементов.
Стало понятно, что просто необходим ресурс в котором можно найти не только общую информацию об OBD2 ошибке, а практические данные по конкретному автомобилю.
Опыт автоэлектриков показал, что если рассматривать определенную марка-модель автомобиля, то в подавляющем большинстве случаев причина возникновения какой либо ошибки одна и также.
Мы создаем, не без вашей помощи, справочник причинно-следственной связи возникновения той или иной OBD2 ошибки у конкретного автомобиля (марка и модель). Если на Ваш автомобиль не найдено описание (причинно-следственной связи) ошибки, то не стесняйтесь задавайте вопрос.
Если у вас есть опыт в устранении той или иной ошибки — делитесь опытом с другими пользователями. Так мы сможем сформировать полезный ресурс. По капле от каждого и всем будет полезно.
Возможно будет интересно:
Если ошибка указывает на неверные параметры (высокие или низкие значения) какого нибудь из датчиков или анализаторов, то вероятней всего этот элемент исправен, а проблему надо искать так сказать «выше по течению», в элементах работу которых анализирует датчик или зонд.
Если ошибка указывает на постоянно открытый или закрытый клапан, то тут надо подойти к решению вопроса с умом, а не менять бездумно этот элемент. Причин может быть несколько: клапан засорен, клапан заклинил, на клапан приходит неверный сигнал от других неисправных узлов.
Автомобили с каждым днем становятся все более сложными, но и более диагностируемыми. Наш форум создан для всех, от простых автолюбителей до профессиональных автоэлектриков.

INTRODUCTION:
This bulletin announces an additional troubleshooting step to follow when diagnosing a DTC U0284: “LOST COMMUNICATIONWITH ACTIVE GRILLE SHUTTER MODULE “A”. Water intrusion into the harness wiring leading to connector B63 for the Active Grille Shutter (AGS) may lead to corrosion of the harness wiring and / or connector terminals and result in a communication loss with the ECM.
PRODUCTION CHANGE INFORMATION:
The installation method of the corrugated plastic harness protection tube was changed to prevent damage starting with the following VINs:
- 4-door: J3624930
- Wagon: J3751997
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
Always refer to the applicable Service Manual and review the full requirements of the repair being performed. The Service Manual procedures contain information critical to performing an effective repair the first time and every time. This includes but is not limited to: important SAFETY precautions, proper inspection criteria, necessary special tools, required processes and related onetime-use parts needed for a complete and lasting repair.
The AGS harness connector B63 is located at the end of the AGS assembly in the l/front as shown below.
IMPORTANT: Before proceeding with any other electrical testing as directed by the current Service Manual diagnostics, access and disconnect the AGS harness connector. The photos below show both sides of the harness connection with corrosion present. If corrosion or an open circuit in the wiring is identified, replace both the bulkhead wiring harness and AGS assembly following the procedure outlined in the applicable Service Manual.
NOTE: Do not attempt to repair the wiring or clean the connector terminals. If there is no corrosion in either connector, check the wiring to the harness connector and confirm there is not an open circuit, broken wire as shown below or unexpected high resistance to indicate corrosion in the wiring. If no wiring or connector damage is identified, proceed with electrical testing Steps 3 to 6 as outlined in the applicable Service Manual for DTC U0284.
The related Service Manuals will be updated with this new initial diagnostic step.
