 System Outline
∗ To reduce driver’s steering force, assist current is calculated from torque sensor signal and vehicle speed signal to output
them to the motor.
∗ When abnormality is found in the system, the power relay and motor relay (Built in the ECU) are shut off to stop the
assistance and the warning lamp (P/S) illuminates in the meter.
