P1A8F CHEVROLET Description
The Starter/Generator Control Module (SGCM) monitors the 14-volt power module current sensor for an overcurrent condition to protect the MOSFET. In the hardware, an overcurrent protection circuit is used to limit the current, and software monitors for an overcurrent reading in the sensor.
