Hyundai Venue: Motor Driven Power Steering / Description and operation
MDPS (Motor Driven Power Steering) system uses an electric motor to assist the
steering force and it is an engine operation independent steering system.
MDPS control module controls the motor operation according to information received
from the each sensor and CAN (Controller Area Network), resulting in a more
precise and timely control of steering assist than conventional engine-driven
hydraulic systems.
Components (Torque Sensor, Fail-safe relay, etc.) of the MDPS system are located
inside the steering column & MDPS unit assembly and the steering column & MDPS
unit assembly must not be disassemble to inspect or replace them.
