Alerts

Signal Name Description Condition Impact
High voltage isolation is too low for the pack to be online.
Isolation is measured to be below the alert threshold while pack contactors are closed
Subpack may not come online
Subpack measurement of internal isolation (within the subpack) is too low.
Internal isolation is measured to be below the alert threshold
Subpack may not come online
The difference in pack voltage measurements of the ADC & BMBs exceeds the maximum limit.
The difference in ADC & BMB pack voltage is greater than 3%
The contactors may open immdediately or pyro disconnect may blow
A pack module temperature is above maximum temperature limit.
A pack module temperature is above maximum temperature limit for X duration (in seconds)
The conactors may open immdediately or pyro disconnect may blow
A brick voltage is below minimum voltage limit.
A brick voltage is below minimum voltage limit for X duration (in seconds)
The conactors may open immdediately or pyro disconnect may blow
A brick voltage is above maximum voltage limit.
A brick voltage is above maximum voltage limit
The contactors may open immediately or pyro disconnect may blow
Incorrect, missing, or unsupported board part number programmed.
HVPACK detects an unexpected board part number
HVPACK is unable to initialize parameters related to printed circuit board assembly (PCBA) configuration
Incorrect or Missing configuration block programmed.
HVPACK config block may be missing, incorrect, or unsupported
HVPACK is unable to initialize configuration parameters
High Voltage Battery Pack (HVPACK) reports the shunt bar temperature is lower than expected.
Shunt bar temperature is outside the expected threshold.
This alert is primarily informational and is used for logging purposes.
Negative contactor is expected to be open but HV current is still present. Possible weld detected.
Contactor state timed out of OPENING (and transitioned to AUX_MISMATCH) due to HV current not being low enough to open contactors.
The pyro fuse may be deployed.
The programmed Bar Resistance Calibration is not being used.
The stored Shunt Bar Resistance was either invalid or the written gain was outside of tolerance.
The default Shunt Bar Resistance will be used. Shunt current measurement accuracy may be reduced.
The battery management system (BMS) detects a condition internal to the high voltage (HV) battery that requires the max allowed brick voltage to be limited.
HVBATT_w723_deltaSocWeakShort is set and (UI_dSocAlertEnable==1 or dSocAlertEnabledByDefault==1).
The target max brick voltage for charge is limited to the voltage corresponding to 50% SOC.
The HvSense measurement Application-specific Integrated Circuit (ASIC) has a Serial Peripheral Interface (SPI) communication fault or other internal fault.
Fault condition was set during SPI communications.
HvSense readings are stale.
The HvSense measurement Application-specific Integrated Circuit (ASIC) is not producing or communicating data.
A timeout has occurred on the expected communication from the ASIC.
HvSense readings are stale.
HV Up is blocked by HVLINK because HVIL is not good.
HVIL is not good and BMS requests that the DC Link be energized
DC Link may fail to energize
The High Voltage Battery Subpack 2 (HVPACK2) is not reporting to the High Voltage DC Link Controller (HVLINK) on the Controller Area Network (CAN).
HVPACK2_interlocks is not received by HVLINK within the MIA qualification time interval.
HVLINK shall assume HVPACK2_pyroTestResponse = 0.
The High Voltage Battery Subpack 1 (HVPACK1) is not reporting to the High Voltage DC Link Controller (HVLINK) on the Controller Area Network (CAN).
HVPACK1_interlocks is not received by HVLINK within the MIA qualification time interval.
HVLINK shall assume HVPACK1_pyroTestResponse = 0.
A crash event has occurred resulting in the potential deployment one or more High Voltage (HV) system pyro fuses.
The Restraint Control Module (RCM) reports a crash via 1kHz Emergency Notification Signal (ENS) tones.
All subpack pyro fuses will be deployed. Fast Charge (FC) pyro fuses may be deployed, and the vehicle may not drive or charge.
A crash event has occurred resulting in the potential deployment one or more High Voltage (HV) system pyro fuses.
The Restraint Control Module (RCM) reports a crash over CAN while Emergency Notification Signal (ENS) tones are absent.
All subpack pyro fuses will be deployed. Fast Charge (FC) pyro fuses may be deployed, and the vehicle may not drive or charge.
The DCLink bus is shorted, preventing the ability to precharge contactors.
The energy consumed by the precharge Integrated Circuit (IC) during a precharge event exceeds the maximum allowed precharge energy.
Precharging will be halted and the vehicle will be unable to precharge its contactors.
