GENERAL DESCRIPTION ON SYSTEM
To improve operational reliability, the dual-circuit sys-
tem has been adopted for the torque sensor. If any
malfunction occurs in the electric power steering sys-
tem, the fail-safe function of the EPS-ECU is acti-
vated, and the output current of the EPS-ECU
applied to the motor is turned off. At the same time,
the steering system enters manual mode, and

informs a driver of the system malfunction by illumi-
nating the warning lamp on the combination meter.
The warning lamp illuminates when the following
malfunctions occur: open circuit in the electric power
steering system wiring harness, poor connection,
malfunctions in the EPS-ECU, motor, or sensors.
Description about function
The vehicle speed signal is sent from the ABS-ECU or
ASC-ECU to the EPS-ECU via the engine-ECU.
Detects a steering force, converts it into the voltage signal,
and then sends the signal to the EPS-ECU.
Generates assist torque by the steering operation to the
column shaft using the signals sent from the EPS-ECU.
Warns a driver of the system malfunction using the signal
sent from the EPS-ECU.
Control the actuator (motor) based on the signal sent from
sensor.
Controls the self-diagnostic function and fail-safe function.
Controls diagnostic function (Compatible with M.U.T.-III).
