Circuit/System Description

The generator control module also called the starter generator control module is comprised of the following three control modules; the hybrid powertrain control module, 14 volt power module and the drive motor control module. These three control modules are non serviceable and are part of the generator control module.

The inverter supply voltage circuit detects the loss of the bias power supply to the insulated gateway bi-polar transistors. This is an internal fault detection of the generator control module. This fault is handled inside the generator control module and no external circuits are involved.
