Circuit Inputs

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Inputs supported by the APM include the high voltage and 12V circuits. The APM also monitors various internal components for current, voltage and temperature. The APM is also connected to the high speed hybrid GMLAN communication circuit. An individual 12V discrete circuit powers ON the APM. The APM will not begin conversion of voltage however, until the appropriate GMLAN enable signal is communicated to it by the HPCM.
