An unexpected software behavior is detected
An unexpected software behavior is detected
Unexpected functionality - depends on the assertion code
No
The Power Conversion System (PCS) controller area network (CAN) receiver encounters an error while receiving messages.
The PCS CAN receiver encounters an error while receiving messages.
DCDC and DCAC may be limited or unavailable.
No
The Power Conversion System (PCS2) did not receive one or more Controller Area Network (CAN) messages from the Front Vehicle Controller (VCFRONT).
The PCS2 does not receive one or more expected CAN messages from VCFRONT.
The PCS2 may limit DCDC functionality to prevent overheating of power electronics components.
No
DCAC converter A (DCACA) resonant tank calibration data is out of specification
A tank capacitance or inductance measurement for DCACA is not withinthe design margin
DCAC operation allowed with default resonant tank parameters at reduced surge current limit
No
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
No
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
No
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
No
The generated power rail (4.5V, 10V, or 18V) has gone above than the allowed upper threshold
The power rail (4.5V, 10V or 18V) has gone above than the allowed upper threshold
DCDC and DCAC may be limited or unavailable.
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
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.
No
The Power Conversion System (PCS) AC tank Gate Drive Power Supply (GDPS) has not been correctly calibrated
The AC tank GDPS calibration data is not present in NVM (AcTankGdpsDataMissing=1), or is not validated (AcTankGdpsDataOutOfSpec=1), or is stale (AcTankGdpsDataStale=1)
The PCS will use inaccurate GDPS calibration data, which may stress the AC tank MOSFETs.
No
The boost converter, which supplies power to various on-board circuits, has a current above the allowed threshold
The boost converter current has gone above the allowed threshold
DCDC and DCAC may be limited or unavailable.
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
DCAC may be limited or unavailable.
No
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.
No
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.
No
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.
No
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.
No
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.
No
The DCAC ENABLE hard line functionality is disabled
