Circuit/System Description

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.

This diagnostic applies to internal microprocessor integrity conditions within the hybrid powertrain control module (HPCM). The HPCM monitors its ability to read and write to the memory. This fault is handled inside the power inverter module (PIM) and no external circuits are involved.
