P0C9F Meaning

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 14V power module has 2 current sensors, one for input and one for output current measurements. This diagnostic checks the output current sensor. These current sensors are internal to the 14V power module and are not serviced separately from the generator control module.
