EPS uses an electric motor to provide directional contol to the driver.
EPS(MDPS=Motor Driving Power Steering)CM always monitors voltage of the motor because current of the motor is controlled by voltage.
Three phase current of the motor is controlled by three phase voltage.
EPS(MDPS=Motor Driving Power Steering)CM sets this code and inhibits EPS control if these voltage values are different from predefined value.
