EPS(MDPS=Motor Driving Power Steering) ECU monitors that operating voltage supplied to the "power supply terminal". If excessive high or low voltage is detected, the EPS(MDPS) stops the current supply to the solenoid to prevent unexpected operation or damage.
EPS (MDPS=Motor Driving Power Steering) sets this code if high voltage caused by faulty alternator or poor connention in power supply circuit is detected.
