Circuit/System Description

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

The drive motor generator power inverter module (PIM) contains two motor control modules (MCM) and a hybrid powertrain control module (HPCM). The MCMs share an internal 15 volt reference power supply in order to operate the drive motor sensors processors. This fault is handled inside the PIM and no external circuits are involved.
