EPS uses an electric motor to provide directional contol to the driver.
EPS(MDPS=Motor Driving Power Steering) CM always monitors current of the motor because power of the EPS system is decided by current.
EPS(MDPS=Motor Driving Power Steering) CM compares current measured by internal current sensor with predefined value at same torque condition.
EPS CM sets this code and inhibits EPS function if a gap between two values is out of specified range.
