The manufacturer has assigned this error or fault code to indicate that the machine has detected a short-circuit in the motor control unit circuit board. Check the wire harness connections between the drive motor and the motor control unit (MCU). Also, check the wire harness connections between the MCU and the central control unit (CCU). If all connections appear sound, it’s possible that the drive motor or motor control unit is defective. If the motor turns at all, change the MCU first.
