Signal Name Description Condition Impact
Pyro fuse is faulted.
Leak test failure or Switch test failure or other failure
Pyro fuse deployment ability is compromised
Pyro squib is disconnected or open-circuit, but pyro circuit is otherwise nominal.
Pyro squib is missing resulting in open-circuit resistance
Pyro fuse deployment ability is compromised
Fault impacting the pyro sub-system.
Pyro operations could not be started
Pyro cannot be deployed
Energy-reserve circuit has a failure.
Voltage of the energy-reserve is out-of-tolerance
Pyro deployment may be compromised
Indicates a 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
Indicates a mismatch between a stack voltage and the sum of its brick voltages.
Any BMB continuously has a stack voltage that doesn't align with the sum of its brick voltages within the in-bounds tolerance
BMB stack and brick voltage signals will be substituted
HVPACK cannot talk to all BMBs.
A communication issue with the BMB daisy chain is detected
May indicate a loss of BMB sensor data
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.
An overcurrent event was detected by hardware, or ER has failed resulting in a pyro fuse deployment.
Passive pyro fuse deployment was detected
Subpack is offline
Pyro fuse deployment was triggered but did not execute.
Software did not successfully deploy the pyro
Pyro deployment may be compromised
Pyro fuse deployment was triggered by firmware.
Pyro fuse deployment was triggered by firmware
Subpack is offline
Pyro fuse may not have cleanly blown, post-mortem diagnostic.
Energy and/or charge delivered to the squib were out-of-tolerance
Pyro deployment may be compromised
Sets immediately on SPI comms errors for visibility into the health of the comms interface.
On single SPI comms error with the asic
ShuntAsicFault is at risk of being triggered soon
Pyro fuse is faulted.
Leak test failure or Switch test failure or other failure
Pyro fuse deployment ability is compromised
Pyro squib is disconnected or open-circuit, but pyro circuit is otherwise nominal.
Pyro squib is missing resulting in open-circuit resistance
Pyro fuse deployment ability is compromised
Data integrity loss due to 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
The HVPACK is likely performing BMB sensor data substitution to replace data missing due to the communication issue
A bmb die temperature is above maximum temperature limit.
A bmb die temperature is above maximum temperature limit for X duration (in seconds)
Brick balancing will be disabled
The shunt measurement Asic is not producing data.
Timeout on expected communication
Shunt readings are stale
Indicates valid data is missing for one or more stack voltages.
One or more stack voltages are continuously detected as invalid
Stack voltage data is likely being substituted to replace invalid readings
Shunt bar temperature is too high.
Shunt bar temperature is too high
Reduced accuracy and physical damage
