DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate that the current sensor value is abnormal. The cause of this malfunction may be one of the following:
Internal inverter malfunctionDESCRIPTION
The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, monitors the motor inverter current sensor. These DTCs indicate the malfunction of current sensors and do not indicate a malfunction of the high-voltage system.
