Signal Name Description Condition Impact Important
Shunt bar temperature is too high.
Shunt bar temperature is too high
Reduced accuracy and physical damage
No
Shunt thermistor is not connected.
Shunt thermistor reading is open-circuit
Subpack may not come online
No
The shunt measurement asic has a SPI communication fault or other internal fault.
Fault condition was set during SPI communications
Shunt readings are stale
No
The shunt measurement Asic is not producing data.
Timeout on expected communication
Shunt readings are stale
No
The HvSense measurement asic has a SPI communication fault or other internal fault.
Fault condition was set during SPI communications
HvSense readings are stale
No
The hvsense measurement Asic is not producing data.

HvSense readings are stale
No
Warns if the Energy reserve voltage supply is below minimum voltage threshold
The Energy reserve voltage supply is below minimum voltage threshold
The pyro diagnostics may fail, the contactors will not close
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
The TCR Coefficient Calibrations are not being used.
The stored Shunt Bar Resistance was either invalid or the written gain was outside of tolerance.
The default TCR coefficients will be used. Shunt current measurement accuracy may be reduced.
No
A communication interruption has been detected in the Battery Monitoring Board (BMB) chain
A communication issue with the BMB daisy chain is detected
May indicate a loss of BMB sensor data
No
Warns if the BMS node is mia on HVI CAN
The BMS node is mia on HVI CAN
CAN messages are not received from BMS or other nodes on vehicle
No
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.
No
Warns if the CP node is mia on HVS CAN
The CP node is mia on HVS CAN
CAN messages are not received from CP node
No
The PCS is MIA and the HVP is power cycling it in an attempt to recover it
The VC indicates that the conditions have been met to power cycle and the HVP has detected no CAN activity from the PCS
The PCS will be power cycled and temporarily no longer support the LV system
No
The programmed Shunt ASIC Calibration is not being used.
The stored Shunt ASIC gain was either invalid or the written gain was outside of tolerance.
The default Shunt ASIC gain will be used. Shunt current measurement accuracy may be reduced.
No
Warns if the shunt current reading is not avaialble
The shunt current reading is not avaialble
Current readings are not avaialble
No
Hvpack is not receiving CAN messages from Hvlink.
Hvpack has not received a message from Hvlink in the MIA qualification time
Hvpack will not allow Hvlink to test the Battery Pack pyro while High Voltage is active
No
Alerts if PyroLeakTest pyro diagnostic has cross warning threshold
PyroLeakTest sees an Aout outside of 15% tolerance when measuring leakage
Customer Facing text to seek service immediately
No
The high voltage processor (HVP) is not receiving messages from the power conversion system (PCS) on the high voltage system (HVS) controller area network (CAN). HVP functions that depend on messages from the PCS may be unavailable, or their performance may be affected.

High voltage processor (HVP) functions that depend on messages from the power conversion system (PCS) may be unavailable, or their performance may be affected.
No
Warns if the voltage and temperature readings from primary BMB chain are mia
The voltage and temperature readings from primary BMB chain are mia
The secondary bmb chain is used exclusively for voltage and temperature protoection
No
