| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
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.
|
|
|
Positive 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.
|
|
|
Tried to close negative contactor but failed because a voltage match was not maintained.
|
Contactor state timed out of PULLED_IN because a voltage match was not maintained.
|
Negative pack contactor will remain open.
|
|
|
Tried to close positive contactor but failed because a voltage match was not maintained.
|
Contactor state timed out of PULLED_IN because a voltage match was not maintained.
|
Positive pack contactor will remain open.
|
|
|
Tried to close negative contactor but failed because the coil drive current was too low.
|
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
|
Negative pack contactor will remain open.
|
|
|
Tried to close positive contactor but failed because the coil drive current was too low.
|
Contactor state timed out of PULLED_IN because of insufficient contactor coil current.
|
Positive pack contactor will remain open.
|
|
|
Did not try to close negative contactor because a voltage match was not achieved.
|
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
|
Negative pack contactor will remain open.
|
|
|
Did not try to close positive contactor because a voltage match was not achieved.
|
Contactor state is OPEN and the PULLED_IN state has been blocked for more than 10s because a required HV voltage match has not been achieved.
|
Positive pack contactor will remain open.
|
|
|
Contactor opened unexpectedly due to insufficient contactor drive voltage.
|
Contactor control state exited CLOSED because of insufficient contactor power voltage.
|
Vehicle may lose propulsion or be unable to support LV system.
|
|
|
Pack contactor exited the economized state unexpectedly. Possibly insufficient coil drive current.
|
Contactor control state exited CLOSED because either of the contactors exited ECONOMIZED.
|
Vehicle may lose propulsion or be unable to support LV system.
|
|
|
Tried to close pack contactors but failed because a voltage match was not maintained.
|
Contactor control state exited CLOSING due to voltage match being lost.
|
Pack contactors will remain open.
|
|
|
The HvSense measurement asic has a SPI communication fault or other internal fault.
|
Fault condition was set during SPI communications
|
HvSense readings are stale
|
|
|
Pack contactors were blocked from opening due to high current. Pyro deployed instead.
|
Pack current is above threshold while trying to open pack contactors.
|
The positive and negative pyro fuses will be deployed.
|
|
|
The battery management system (BMS) has encountered an issue while charging or attempting to charge.
|
The BMS detects a condition that prevents it from starting charging.
|
Inability to charge, drive, or support the low voltage (LV) system
|
|
|
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.
|
|
|
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
