P0C0B Meaning
This is a detection of an internal fault in the generator power inverter module (PIM) assembly of the drive motor. The PIM monitors the drive motor “1” inverter. The ECM sets the OBDII code when the drive motor “1” inverter does not meet factory specifications. This fault is handled inside the PIM and no external circuits are involved.
