P1B01 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. MCM 1 programs the PLD with software at every ignition ON event. MCM 1 and 2 verify that the PLD is programmed successfully.
