WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Each electric motor generator located within the transmission assembly is controlled by its own motor control module (MCM) flash-programmable, micro-processor. Each MCM is contained within the PIM. Also contained within the PIM is the hybrid powertrain control module (HPCM) micro-processor.
