GENERAL DESCRIPTION ON SYSTEM





ELECTRICAL PARTS AND FUNCTIONS


Parts name
 Description about function
Sensor
 Wheel speed sensor (ABS-ECU or ASC-ECU)
 The vehicle speed signal is sent from the ABS-ECU or ASC-ECU to the EPS-ECU via the engine-ECU.
Torque sensor
 Detects a steering force, converts it into the voltage signal, and then sends the signal to the EPS-ECU.
Actuator
 Motor
 Generates assist torque by the steering operation to the column shaft using the signals sent from the EPS-ECU.
Electric power steering warning lamp (in combination meter)
 Warns a driver of the system malfunction using the signal sent from the EPS-ECU.
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).
