Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
The cost to diagnose the P0CA2 CADILLAC code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
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 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.
