General Description
PS uses an electric motor to provide directional contol to the driver.
To confirm operating state of the motor is essential for controlling the EPS(MDPS=Motor Driving Power Steering) system as intended.
DTC Description
ESP(MDPS=Motor Driving Power Steering) CM measures motor velocity by using motor position sensor and motor output torque by using current sensor to confirm whether the motor operates normally or not. After measure then it compares measured values and calculated values. EPS CM sets this coed and turns on warning lamp if there is a difference between two values.
