P0CA2 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 14V power module has switching transistors that allows it to convert high voltage from the Hybrid Battery to 12 volts. This diagnostic is designed to test for an electrical short in the MOSFET transistors. The transistors are internal to the 14V power module and cannot be serviced separately from the generator control module.
