Circuit/System Description

WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

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.
