Circuit/System Description
The drive motor generator battery control module will diagnose its own systems and determine when a fault condition is present. Diagnostics and
system status is communicated from the drive motor generator battery control module to the drive motor generator control module through serial
data. The drive motor generator control module is the host controller for diagnostic trouble code (DTC) information.
