|---|---|---|---|
|
The Power Conversion System (PCS) ADC reference has not been correctly calibrated.
|
The ADC reference data is not present in non-volatile memory (adcReferenceDataMissing=1) or is not validated (adcReferenceOutOfSpec=1).
|
The PCS will use the default ADC reference of 1.0.
|
|
|
The Power Conversion System (PCS2) detects the previous Direct Current to Direct Current (DCDC) Burst Mode on cycle did not complete in time, indicating there are still burst patterns that are not loaded into the Pulse Width Modulation (PWM).
|
The PCS2 detects the previous DCDC Burst Mode contains a switching pattern that is no loaded into the Pulse Width Modulation (PWM) module.
|
DCDC Burst Mode may not operate as expected.
|
|
|
The Power Conversion System (PCS) is unable to regulate internal voltage rails.
|
The buck-boost converter did not reach the desired voltage.
|
DCDC and DCAC may be limited or unavailable.
|
|
|
The Power Conversion System (PCS2) detects the voltage sensor readings before and after the AC relay does not match the expected behavior of the given AC relay state.
|
The AC relay voltage difference exceeds the expected threshold.
|
DCAC functionality may be limited or paused.
|
|
|
The Power Conversion System (PCS2) detects that the DCAC converter's shared leg current is not shared evenly when the legs are shorted by either the AC harness or the AC relay.
|
The shared leg current difference exceeds the expected threshold.
|
The DCAC converters will have reduced power capabilities.
|
|
|
The DCAC ENABLE hard line functionality is disabled
|
The DCAC ENABLE line functionality is disabled
|
The high voltage battery controller (HVBATT) cannot force shutdown DCAC by de-asserting the DCAC ENABLE line
|
|
|
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
|
|
|
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 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
|
|
|
The high voltage (HV) battery top voltage measurement is irrational
|
The HV battery top voltage is irrationally high or low
|
DCDC and DCAC may be limited or unavailable.
|
|
|
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
|
DCAC may be limited or unavailable.
|
|
|
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
|
|
|
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
|
|
|
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
|
|
|
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
|
|
|
The Power Conversion System (PCS) detects the initial high voltage (HV) bus voltage is too high to measure capacitance, so it must rely on the maximum possible capacitance value instead for HV bus impedance estimation.
|
The initial HV bus voltage is too high to measure capacitance, so PCS must use maximum possible capacitance value to estimate HV bus impedance.
|
PCS may underestimate the HV bus impedance.
|
|
|
The Power Conversion System (PCS) cannot precharge the high voltage (HV) bus.
|
The PCS detects one or more conditions preventing it from precharging the HV bus to its commanded voltage target
|
The DCDC converter may not precharge the HV bus to its commanded voltage target, preventing HV battery pack contactors from closing.
|
|
|
The onboard charger has consumed all of its available retries and blocked further AC charging attempts.
|
The onboard charger detects a condition requiring it to stop AC charging multiple times within one charge session.
|
Inability to AC charge.
|
|
|
The onboard charger detects power is removed while charging, making AC charging unavailable.
|
Charger detects wall power was unexpectedly removed while charging.
|
Inability to AC charge.
|
|
|
The Power Conversion System (PCS) detects the estimated high voltage (HV) bus impedance is lower than the expected threshold.
|
The estimated HV bus impedance is lower than the expected threshold.
|
The DCDC converter may not precharge the HV bus to its commanded voltage target, preventing HV battery pack contactors from closing.
