DTC Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
The MDPS is designed to operate only at engine "ON" because it's current attrition rate is high. It decides whether motor operates or not from vehicle speed and motor RPM. The MDPS ECU sets this code and turns on warning lamp, if ignition switch turns off when motor is operating.
