Monitor Description

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

If too much current is detected flowing through the motor inverter, the motor inverter transmits an inverter fail signal to the motor generator control ECU. Upon receiving this signal, the motor generator control ECU will illuminate the MIL and set a DTC.
