Fail Saf

- EPS system enters the fail-safe mode (that allows the steering

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
