Circuit/System Description

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

The drive motor generator power inverter module contains two motor control modules and a hybrid powertrain control module. The motor control modules share an internal 15 V reference power supply in order to operate the drive motor sensors processors. This fault is handled inside the drive motor generator power inverter module and no external circuits are involved. The motor control modules and the hybrid powertrain control module are part the drive motor power inverter module and are not serviced separately.
