SYSTEM DESCRIPTION DESCRIPTION (a) The power steering ECU (rack and pinion power steering gear assembly) generates the necessary steering assist torque by calculating the steering assist force and controlling the motor current, based on the steering torque information from the torque sensor (rack and pinion power steering gear assembly), vehicle speed information from the skid control ECU (brake actuator assembly), and information from the ECUs. (b) When there is a drop in the power source voltage, the rear window defogger, windshield deicer, outer mirror heater, PTC heater and seat heater operations are limited as part of power steering system load control. (c) When there is a drop in the power source that may require an increase in steering force, the system illuminates the power steering warning light in order to warn the driver.
