For a description of the inverter.
Refer to DESCRIPTION
If the rear motor inverter overheats, has a circuit malfunction or internal short, the inverter transmits this information to the MG ECU via the rear motor inverter fail signal line.
If an abnormal amount of current flows through the rear motor inverter, the MG ECU detects it and sends a signal to inform the power management control ECU of the malfunction.
HINT:
The term "drive motor B" indicates the rear motor (MGR).
