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. MCM 1 programs the PLD with software at every ignition ON event. MCM 1 verifies that the PLD is programmed successfully.
