P16F9 CHEVROLET Description
This diagnostic applies to internal microprocessor integrity conditions within the Hybrid Powertrain Control Module (HPCM). The HPCM and each Motor Control Module (MCM) utilize a programmable logic device (PLD) to perform certain input and output functions. The HPCM monitors the ability of the PLD to perform these functions.
