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.
This diagnostic applies to internal microprocessor integrity conditions within the drive motor generator battery control module. This is an internal
electronic fault detection diagnostic of the drive motor generator battery control module. This fault is internal to the drive motor generator battery
control module and no external circuits are involved.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The drive motor generator battery control module has detected an internal malfunction.
