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.
EPS(MDPS=Motor Driving Power Steering) ECU compares current measured during certain Torque conditions.
EPS ECU sets this code and inhibits EPS function if a gap between two values is out of specified range.
