None displayed
The DCDC converter may not enable, resulting in no power conversion system (PCS) support for the low voltage (LV) battery and electrical system.
The front vehicle controller (VCFRONT) has detected a condition affecting the reverse battery charge pump.
VCFRONT detects a high drop in voltage across protection field effect transistors (FETs) is high or the charge pump voltage is low.
VCFRONT no longer detects a condition affecting the reverse battery charge pump (high drop in voltage across FETs or low charge pump voltage).
