P1A64: Understanding The Hybrid/Ev Battery Charge System Fault
The P1A64 fault code is related to the StarterGenerator Control Module (SGCM). The Accessory Power Module (APM) is integral to the SGCM and controls the energy flow between the 42 V DC and 14 V DC buses.
The APM power is bi-directional, with negative current representing 14-42 direction, and positive current representing the 42-14 direction. When the APM Power Conversion direction is set to Off, the APM will not consume or transfer any power.
If the APM Power Conversion direction is set to Invalid, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM.
