The Power Conversion System (PCS) does not receive one or more DCDC interface Controller Area Network (CAN) messages from the Vehicle Controller (VC)
The PCS does not receive all expected DCDC interface CAN messages from the VC
DCDC may not be able to regulate the LV bus voltage requested by the Vehicle Controller (VC)
The Power Conversion System (PCS) DCDC HVDC Gate Drive Power Supply (GDPS) has not been correctly calibrated
