|
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 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
|

|
|
|
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)
