DTC P321E-9F: Motor/Generator Shutdown Signal Stuck Off [04/2018 - 08/2020]: Description
WARNING: This page is about a different car, the 2020 Toyota Avalon and 2019 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
The hybrid vehicle 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 hybrid vehicle 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.
