Signal Name Description Condition Impact Important
Charging faulted due to too large of a voltage drop between starting charge and during charge
Charger detects greater than 14% input voltage drop after ramping power
Inability to AC charge, possibly due to bad wiring external to vehicle
No
The high voltage (HV) battery top voltage measurement is irrational
The HV battery top voltage is irrationally high or low
DCDC and AC Charging may be limited or unavailable.
No
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.
No
The Power Conversion System (PCS2) self-performed MOSFET health check is unsuccessful on Cyclo Converter B
The PCS2 ECU does not pass the self-performed MOSFET health check on Cyclo Converter B
AC Charging may be limited or unavailable.
No
The AC Line 3 current has an irrationally high DC offset
The AC Line 3 current has an irrationally high DC offset
AC Charging may be limited or unavailable.
No
The Power Conversion System (PCS) has been placed into functional test mode
A request is issued to the PCS to place itself into functional test mode
The PCS may become damaged if operated in an uncontrolled environment
No
DCDC transient power capability is detected to be reduced and impacted
One or more conditions occur that impact DCDC transient power capability
DCDC transient capability will be reduced
No
PCS does not receive CAN messages from VCRIGHT
PCS does not receive all expected CAN messages from right vehicle controller
DCDC functionality may be limited
No
The DCAC lifetime kVAh record is not ready for use
Lifetime kVAh accumulation counters for DCAC is not in an expected state
Lifetime kVAh accumulation counters for DCAC cannot be stored
No
The high voltage (HV) side of the pack side DCDC converter (DCDCB) temperature is too high
DCDCB HV temperature exceeds the allowed temperature threshold
DCDC functionality may be limited or paused
No
The Power Conversion System (PCS2) has detected that one of its DCDC stage's resonant tank current zero-crossing event measured timing is continuously out of our control
The Power Conversion System (PCS2) has detected the resonant tank's zero-crossing behavior is out of its control, resulting in zero-crossing event measured timing being irrational
The impacted DCDC stage may have a hardware integrity issue and may not be able to deliver power to its output
No
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
No
The Power Conversion System (PCS2) detects the microgrid frequency droops below its nominal level indicating microgrid is under heavy load
The PCS2 ECU detects the microgrid frequency droops below its nominal level
AC charging power will be temporarily limited depending on the droop level to reduce the load on the microgrid
No
The Power Conversion System (PCS2) has failed the self-performed Gate Drive Power Supply (GDPS) health check on Cyclo Converter B
The PCS2 ECU does not pass the self-performed GDPS health check on Cyclo Converter B
AC Charging may be limited or unavailable.
No
PCS DCDC hardware enable line does not match CAN signal
DCDC converter detects that sensed enable hardline state does not match state reported on CAN for more than five seconds
Inability to precharge HV bus, inability to support 12V system, inability to drive
No
PCS DCDC detects 12V bus voltage is lower than the safety threshold to continue its operation
DCDC converter detects that low voltage bus voltage is below undervoltage threshold
Inability to precharge HV bus, inability to support 12V system, inability to drive
No
PCS charging hardware enable line does not match CAN signal
Charger detects that sensed enable hardline state does not match state reported on CAN for more than five seconds
Inability to AC charge
No
Charger detects unknown grid configuration
Charger detects unknown grid configuration
Inability to AC charge, possibly due to incompatible grid
No
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)
No
The Power Conversion System (PCS) DCDC HVDC Gate Drive Power Supply (GDPS) has not been correctly calibrated
The DCDC HVDC GDPS calibration data is not present in NVM (DcdcHvdcGdpsDataMissing=1), or is not validated (DcdcHvdcGdpsDataOutOfSpec=1), or is stale (DcdcHvdcGdpsDataStale=1)
The PCS will use inaccurate GDPS calibration data, which may stress the DCDC HVDC MOSFETs.
No
