MDPS (Electric power steering, Column assist type) 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.
