P0C76 CHEVROLET MeaningThe 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 generator control and battery module assembly contains a high voltage contactor. The high voltage contactor allows the high voltage DC batteries to be connected to the vehicle and safely contain the high voltage DC within the generator control and battery module assembly. The high voltage contactor is connected in series with the positive side of the DC voltage potential of the high voltage battery. The hybrid powertrain control module supplies ground to the control circuit of the high voltage contactor to close.
