Доброго времени суток, уважаемые форумщики Крайслер Клуба.
Jeep Cherokee (Liberty) 2001г.в. 3,7 Limited Edition.
Авто приобрёл чуть больше полтора месяца назад. Мой первый автомобиль.
Половину месяца отъездил нормально, а после начались проблемы, думаю, в решение которых можно положиться на вас.
Началось всё с того, что загорелся на панели приборов сам по себе Chek. Но ездил нормально, ничто нигде не глючило. После появилась такая проблема как — поездил по городу остановился, заглушил двигатель, а обратно он не заводился, приходилось ждать минут 15-30 и всё приходило в норму (прошлй владелец говорил что у него такое было)
Позже, недели через 2 загорелась ABS, хотя она работает (стучит педаль), а ещё недели через 2 загорелся значок ручника Brake. И в «конце» он мне выдал такой номер что стал глохнуть на ходу (причём почти всегда сразу же и заводится с ключа). А потом и отключился спидометр, просто перестал показывать.
В итоге выдаётся 3 ошибки P0500,P1687,P1686
P0500 — неисправен датчик скорости. Оказалось что неисправен датчик скорости на переднем колесе. Заказали, его привезли через 3 недели. Поставили, а всё осталось по-прежнему (только глохнуть на ходу стал меньше). Ставили другую АБС (новую) и 0 результатов.
Так сейчас и езжу без спидометра и с периодически глохнущим двигателем.
И, да, заметил 2 раза одну вещь — когда с утра еду в универ (около 10км) то авто глохнет на одном и том-же месте, встаю, завожу и нормально.
Подскажите, пожалуйста, в чём причина, т.к. был на нескольких СТО, делали диагностики, и не знают что это. Jeep’ов Liberty у нас почти нет в городе.
0500 — это ошибка не датчика АБС на переднем колесе, а ошибка датчика скорости машины, который стоит на коробке. Вот Вам и неработающий спидометр. Если загорелась лампочка BRAKE проверьте сначала уровень жидкости в тормозном бачке.
Ошибка 1686 относится к тому, что пропадает сигнал с иммобилайзера (вот вам и глохнущий мотор), 1687 — пропадает связь между приборкой и центральными «мозгами». Очень похоже, что у Вас дурит проводка, проверьте ее от рулевой колонки (иммобилайзер) и до приборки, просмотрите все разъемы под торпедо ну и т.д.
Что включала в себя «диагностика» на СТО? НАйдите пожалуйста станцию у которой есть сканер DRB и прочитайте показания всех датчиков и ошибки АБС в режиме он-лайн. Только так получите полную и ясную картину.
А вот по кодам ошибок можно было поиском по ФАКу пройтись и сразу бы Вам стало ясно, где собака порылась.
