P1a6a Gmc Description

The purpose of the Accessory Power Module (APM), integral to the Starter/Generator Control Module (SGCM), is to control the amount and direction of energy flowing between the 42 V DC and 14 V DC buses via the APM, bi-directional 42 V DC to 14 V DC converter. All APM functions will only be run when in the enable mode. APM current will be defined as the current flowing through the outputs. 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 a value of 42 V to 14 V, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM. When the Service Charge or jump starting is requested, the energy will flow from the 14 V DC Bus to the 42 V DC Bus via the APM. When the APM Power Conversion direction is set to a value of Off, the APM will be turned off, and not consume or transfer any power. When the APM Power Conversion direction is set to a value of Invalid, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM.
