P STC-3 Revision: 2008 August 2009 Rogue EPS SYSTEM FUNCTION DIAGNOSIS EPS SYSTEM System Diagram INFOID:0000000004233083 JSGIA0159GB System Description INFOID:0000000004233084 ? EPS control unit 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. ? EPS control unit decreases the output signal to EPS motor while extremely using the power steering func- tion e.g., full steering consecutively for protecting EPS motor and EPS control unit Overload protection control . While activating overload protection control, the assist torque gradually decreases, and the steering wheel turning force becomes heavy. The normal assist torque reactivates by no steering. ? In case of an error in the electrical system, the fail-safe function stops output signals to the EPS motor. Then the previous state is changed to the manual steering state. ? Self-diagnosis can be done with CONSULT-III. ? EPS control unit will decrease assistance under the following 2 conditions. - Extensive steering at low speed will cause the ECU and MOTOR to heat up, once temperature reaches crit- ical point ECU will reduce current to reduce heat up. System will recover as temperature lowers reduced or no assistance . - Holding steering on rack-end full lock for 1 second will cause the system to engage rack-end protection. This reduces assistance down to 50% in order to prevent heat up. Assistance is immediately returned to 100% when steering released or turned away from rack-end.
