WARNING: This page is about a different variant/trim than selected.

The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, monitors the rear motor inverter current sensor. These DTCs indicate the malfunction of current sensors and do not indicate a malfunction of the high-voltage system.
