Location
The HPCM is a non-serviceable, flash-programmable micro-processor contained within the PIM assembly.
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.
The APM is affixed to and located underneath the PIM. It is fastened to the PIM with external mounting fasteners and 2 internal high voltage circuit connection fasteners. The APM shares a coolant passage with the PIM and as such is gasketed to the PIM.
