Привет!
Я сам владелец LandRover Discovery. И как то у меня загорелась лампочка ABS. Первый раз я заехал на сервис и за 25$ мне ее погасили. Второй раз пришлось искать в интернете ресурсы как сделать это самому. Спасибо Jim and Jan который помог мне с разобраться с диагностикой ABS.
LandRover Discovery оснащен разъемом стандарта OBD-II (OnBoardDiagnostic-II). Этот разъем идет на автомобилях с года выпуска 1996 и позже. На LandRover Discovery 1996 (у меня такой) этот разъем присутствует под рулевым управлением ниже фальшпанели. В некоторых машинах необходимо открыть 2 винта что бы сбросить фальшпанель, так как разъем может быть засунут внутрь вместе со жгутами проводов. Разъем имеет вид:

Нас интересуют следующие контакты:
Коды ошибок выдаются по двум очередям вспышек. Расшифровка кодов приведенв в таблице.
