DTC P321E-318: All HV Gate Blocking Range/Performance [02/2014 - 11/2016]: Description

The power management control ECU sends a block signal to the motor generator control ECU (MG ECU) to shutdown 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 power management control ECU 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.

When the HV gate block function check is performed (when the power switch is turned from on (READY) to off), the inverter voltage (VH) drops and current flows in the inverter. (The generator (MG1), motor (MG2) and rear motor (MGR) are malfunctioning.)
