Code P0C01 GMC Description
The drive motor control module operates the starter generator, also referred to as the drive motor based upon hybrid powertrain control module commands. The drive motor control module controls the speed and output torque of the starter generator through the sequencing actuation of high current switching transistors called insulated gate bipolar transistors. Each insulated gate bipolar transistor assembly is monitored for overcurrent conditions.
