Ниссан марч ошибка c1606

EPS motor provides the assist torque by control signal from EPS control unit.

DTS Display item Malfunction detected condition Possible cause
C1606 EPS MOTOR When the motor driver malfunction of EPS control
unit or EPS motor malfunction is detected.		 • Harness or connector
• EPS motor
• EPS control unit

Мотор EPS обеспечивает вспомогательный крутящий момент по сигналу от блока управления EPS.

Возможные причины

  • ESP мотор
  • Проводка и разъёмы
  • Блок управления

Блок управления EPS выполняет арифметическую операцию с данными, такими как сила поворота рулевого колеса (
сигнал от датчика крутящего момента, сигнал скорости автомобиля и т. д. Затем он генерирует оптимальный вспомогательный крутящий момент для мотора EPS в зависимости от условий движения
