The EPS(MDPS=Motor Driving Power Steering) uses an electric motor to provide assistance to the driver while turning the steering wheel.
The EPS ECU monitors the current of the motor to determine if there is a fault.
Three phase current of the motor is controlled by three phase voltage.
EPS(MDPS=Motor Driving Power Steering)ECU sets this code and inhibits EPS control if these voltage values are different from predefined value.
