Signal Name Description Condition Impact
The high voltage (HV) bus goes above the allowed voltage threshold
The HV bus voltage goes above the allowed voltage threshold
DCDC functionality may be limited or paused
The DCDC ENABLE hard line functionality is disabled
The DCDC ENABLE line functionality is disabled
The high voltage battery controller (HVBATT) and vehicle controller (VC) cannot force shutdown DCDC by de-asserting the DCDC ENABLE line
The low voltage (LV) side of the DC link DCDC converter (DCDCB) temperature is too high
DCDCB LV temperature exceeds the allowed temperature threshold
DCDC functionality may be limited or paused
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)
PCS does not receive CAN messages from VC that manages the low voltage battery
PCS does not receive all expected CAN messages from VC that manages the low voltage battery
DCDC functionality may be limited
The Power Conversion System (PCS) DC tank Gate Drive Power Supply (GDPS) has not been correctly calibrated
The DC tank GDPS calibration data is not present in NVM (DcTankGdpsDataMissing=1), or is not validated (DcTankGdpsDataOutOfSpec=1), or is stale (DcTankGdpsDataStale=1)
The PCS will use inaccurate GDPS calibration data, which may stress the DC tank MOSFETs.
The Non-Volatile Memory (NVM) server encountered at least one error during initialization
A step in the NVM server initialization sequence returns an error indication
NVM record servicing is not possible, making Power Conversion System (PCS2) functionality limited or unavailable
The AC Line 2 to Neutral voltage has an irrationally high DC offset
The AC Line 2 to Neutral voltage has an irrationally high DC offset
DCAC may be limited or unavailable.
The AC Line 3 to Neutral voltage has an irrationally high DC offset
The AC Line 3 to Neutral voltage has an irrationally high DC offset
DCAC may be limited or unavailable.
The AC Line 1 current has an irrationally high DC offset
The AC Line 1 current has an irrationally high DC offset
DCAC may be limited or unavailable.
The AC Line 2 current has an irrationally high DC offset
The AC Line 2 current has an irrationally high DC offset
DCAC may be limited or unavailable.
The AC Line 3 current has an irrationally high DC offset
The AC Line 3 current has an irrationally high DC offset
DCAC may be limited or unavailable.
The AC Line N current has an irrationally high DC offset
The AC Line N current has an irrationally high DC offset
DCAC may be limited or unavailable.
The Power Conversion System (PCS) detects the DCAC ENABLE digital line is deasserted when DCAC is still commanded to operate
The PCS detects the DCAC ENABLE digital line is deasserted when DCAC is still commanded to operate
DCAC converters will be forced shutdown due to the ENABLE line deassertion
The low voltage (LV) bus goes below the allowed voltage threshold
The LV bus voltage goes below the allowed voltage threshold
DCAC may be limited or unavailable.
The low voltage (LV) bus goes above the allowed voltage threshold
The LV bus voltage goes above the allowed voltage threshold
DCAC may be limited or unavailable.
During AC charging, the measured root mean squared (RMS) voltage across the lines has decreased below the voltage drop threshold when compared to the RMS voltage at the start of AC charging
The RMS voltage across the lines has decreased below the voltage drop threshold
Reduced AC charge rate
The Power Conversion System (PCS) has been placed into manufacturing EOL (End of Line) mode
EOL mode is enabled from the specific UDS routine
The PCS should only be operated in this mode during EOL testing. Operating the PCS in this mode outside of EOL testing may result in undefined behavior.
The temperature of the thermal model for the DCDC low voltage (LV) metal-oxide-semiconductor field-effect transistors (MOSFETs) becomes too high
The temperature of the thermal model for the DCDC LV MOSFETs rises above its set limit
The maximum DCDC power may be reduced
The temperature of the thermal model for the DCDC transformer windings becomes too high
The temperature of the thermal model for the DCDC transformer windings rises above its set limit
The maximum DCDC power may be reduced
