October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
System Description: Notes
- EPS system consists mainly of power steering control module, EPS motor, power steering torque sensor.

- EPS system calculates a control signal to transmit to the EPS motor based on information received from ECM, ABS actuator and electric unit (control unit), steering angle sensor, chassis control module, and combination meter via CAN communication and information received from torque sensor.
- Power steering control module performs an arithmetical operation on data, such as steering wheel turning force (sensor signal) from the torque sensor, vehicle speed signal, etc. Then it generates an optimum assist torque signal to the EPS motor according to the driving condition.
- After engine start, the EPS system performs control.
- When a malfunction occurs in the system, the fail-safe function stops the EPS system (manual steering state) or restricts its operation (Constant steering assist level state). Refer to Fail-safe .
- Power steering control module decreases the output signal to EPS motor while extremely using the power steering function (e.g., full steering) consecutively for protecting EPS motor and power steering control module (Overload protection control). Refer to Protection Function .
- Infiniti drive mode selector which can change the steering characteristic corresponding to the preference of the driver was adopted. For details, refer to System Description
