это изменение протокола общения с контроллером

может у вас сбилась настройка

а мы тут головову ломаем и желоезо ковыряем

кстати да в этих разъемах часто контакт пропадает

или вылазиет в обратную сторону, потому как фиксатор загнулся

думал что провода проверены уже

В итоге что было ? 
у меня просто видимо такая же проблема обнаружилась на курке lh-100. При включении курка и сразу нажатии на газ то реакция есть на 1 секунду а потом появляется ошибка e-10. На другом курке тоже самое.

переткните все разъемы от БК до контроллера

прозвоните

Попробую сделать это. У меня это началось все когда вечером вчера при повороте руля у меня стал вырубаться курок (стал искать возможный обрыв) Нашёл в итоге его и соединил все 5 проводов которые идут на курок. После этого курок стал включаться на пол секунды и гаснуть. Сегодня дали два курка на тест и вот с ними происходит ошибка е-10(( Пол дня сегодня вожусь с этим делом и не могу понять в чем причина

Ну по линии вроде все ок (которая идёт от фишки курка и до контроллера) Может дело в распиновки курка? У меня до этого курок был где провод шёл цельный без круглого разъёма. Пробовал менять местами зелёный и желтый но результата не получил. Может стоит чёрный или синий поместить за место зелёного или желтого?

Восстановил старый курок (перебит где то минус) По итогу моторы стали крутиться и все вроде заработало. Но ошибка е-10 не перестала гореть.
