Alerts

Signal Name Description Condition Impact Important
The High Voltage Battery (HVBATT) detects the Charge Port High Voltage Interlock Loop (CPIL) is open.
The HVBATT has detected that CPIL is open.
The vehicle may be unable to charge.
No
The configured battery pack 1 passive pyro setpoint is invalid
The configured battery pack 1 passive pyro setpoint is invalid
Vehicle performance may be reduced
No
Low-side shunt active sense and passive sense readings are not in agreement
Low-side shunt active sense and passive sense readings have a delta outside of the acceptable margin
Low-side sub pack may not come online
No
Low-side shunt bar temperature is too low
Low-side shunt bar temperature is too low
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
No
Low-side shunt detects shunt connector as disconnected
Low-side shunt active current reads 0A, passive current reflects open circuit conditions
Low-side sub pack may not come online
No
A brick voltage is above the fault voltage limit
A brick voltage is above the fault voltage limit for X duration (in seconds)
The vehicle may not drive or charge.
No
Low-side shunt active sense current reading deviates from zero when contactors are open
Contactors are open and low-side shunt active sense reading is larger than acceptable margin
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
No
Indicates valid data is missing for one or more brick voltages
One or more brick voltages are continuously detected as invalid
Brick voltage data is likely being substituted to replace invalid readings
No
Indicates a Battery Monitoring Board (BMB) reference voltage has continuously been out of bounds
Any BMB reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage
Other BMB voltage signals will be substituted given the reference voltage is unreliable
No
The BMS has detected isolation failure conditions in several drive sessions
Isolation or isolation degradation alert is set in several drive sessions
Vehicle may be unable to restart
No
A battery pack 1 brick voltage is below the over discharged voltage limit
A battery pack 1 brick voltage is below the over discharged voltage limit for X duration (in seconds)
The vehicle may not drive.
No
Low-side shunt bar temperature is too high
Low-side shunt bar temperature is too high
Low-side pack HV will be blocked. The shunt may become physically damaged.
No
The low-side shunt measurement asic has a SPI communication fault or other internal fault
Fault condition was set during SPI communications
Low-side shunt readings are stale
No
Data integrity loss due to Battery Monitoring Board (BMB) chain double break
A prolonged communication issue with the BMB daisy chain that is known to cause a loss of BMB sensor data is detected
BMB sensor data is likely being substituted to replace data missing due to the communication issue
No
Incorrect or Missing configuration block programmed
ECU config block may be missing, incorrect, or unsupported
ECU is unable to initialize configuration parameters
No
Measurement of internal isolation (within the pack) is too low
Internal isolation is measured to be below the alert threshold
Pack may not come online
No
The Drive Inverter (DI) High Voltage Interlock Loop (HVIL) is reporting as unknown, breaking the overall High Voltage Battery (HVBATT) HVIL.
The DI HVIL is reported as unknown.
Vehicle may be unable to enter drive and may be unable to charge.
No
High-side pyro low-side switch (SR FET) is non-functional.
High-side pyro-P voltage does not rise to within a margin of the energy reserve voltage when the SR FET is enabled.
High-side pack High Voltage will be blocked, charge and drive may be unavailable.
No
There was an attempt to deploy the high-side pyro, but it was unsuccessful.
The firmware could not successfully trigger a high-side pyro deployment or there was an attempt to deploy the high-side pyro while the deployed test was actively running for the high-side pyro.
The vehicle may not drive or charge.
No
Negative contactor opened unexpectedly due to insufficient coil drive current.
Contactor state exited ECONOMIZED because coil current was too low.
Vehicle may lose propulsion or be unable to support LV system.
No
