Description of EPS System Component Function

EPS SYSTEM COMPONENT FUNCTION CHART

EPS system components		Function
Steering gear case assembly	Rotation angle sensor	It consists of an exciter winding and 2 sets of fixed detector winding. It outputs signals proportional to motor rotation angle to P/S control module.
	Torque sensor	Torque sensor consists of main and sub systems and outputs voltages that correspond to steering torque and direction to the P/S control module.
	P/S motor	P/S motor assists steering action by generating torque proportional to the amount of current from the P/S control module.
P/S control module		P/S control module determines the amount of current and the direction to assist based on the output voltage from torque sensor, the motor rotation angle detected by rotation angle sensor, the vehicle speed signal from CAN communication, etc. to control P/S motor. P/S control module determines engine condition (running or stopping) based on engine speed signal from CAN communication.
"P/S" warning light		"P/S" warning light turns on when a problem occurs in P/S system.
