Fail Saf

EPS system

  • EPS system enters the fail-safe mode (that allows the steering
    force to be controlled without impairing the drive ability) if any of
    the input/output signals to/from EPS system (power steering control
    unit) deviate from the standard.
    NOTE:
    The system enters the fail-safe mode if the engine speed remains
    at 1,500 RPM or more for over 10 seconds while the vehicle is
    stopped. This is normal.
  • The fail-safe function is cancelled when a vehicle speed signal of 2
    km/h (1.2 MPH) or more is inputted or the key switch is turned
    OFF→ ON. EPS system restores the normal operation at that time
