Индикатор Check Engine Light (CEL)

Индикатор Check Engine Light (CEL) на панели приборов сигнализирует о том, что ЭБУ обнаружил проблему. ЭБУ обычно отображает код ошибки, мигая CEL определенным образом.


Диагностика по поколениям:

  1. OBD0:
    • На ЭБУ имеется окошко, через которое виден мигающий светодиод (LED), отображающий коды ошибок.
  2. OBD1:
    • Под торпедо со стороны пассажирской ноги расположен диагностический разъем.
    • Для считывания кодов его нужно замкнуть, после чего CEL на приборной панели начнет мигать, отображая коды ошибок.
  3. OBD2:
    • Разъем находится под торпедо со стороны пассажирской ноги.
    • После замыкания разъема CEL начнет мигать, как в OBD1.
    • Для считывания можно также использовать сканер OBD2, который подключается к серому разъему у водительской ноги.

Непрерывно горящий CEL (Solid CEL):

Если CEL горит постоянно и не мигает после замыкания диагностического разъема (OBD1), и автомобиль работает плохо, возможные причины:

  • Неисправный ЭБУ.
  • Плохие соединения пайки.
  • Ошибка контрольной суммы (Check Sum Error).
  • Неисправная программа, записанная в ROM.
  • Неисправный чип ROM.
  • Неисправный чип 74HC373.

Подробнее: Troubleshooting Solid CEL.


“Фантомный” CEL:

Иногда CEL появляется, но пропадает после выключения зажигания. Для диагностики:

  1. Не выключайте зажигание.
  2. Замкните диагностический разъем, как обычно.
  3. CEL погаснет на короткое время, а затем начнет мигать коды ошибок.
