The hybrid vehicle control ECU assembly sends a block signal to the motor generator control ECU (MG ECU) to shut down the power supply to the motor. When the system is not in the on (READY) state, it sends an HSDN (MG shutdown signal) signal from the hybrid vehicle control ECU assembly to the motor generator control ECU (MG ECU) to check the function of the HV gate block. When a malfunction is detected in the HV gate block function, DTCs are stored.
