Code P061A GMC Description

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. The HPCM processor monitors the data to verify that the indicated torque calculation is correct. The HPCM is located within the Drive Motor Generator Power Inverter Module (PIM) and is not serviceable separately. The HPCM sets the OBDII code when the control module has detected the internal software calculation.
