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.
Positive 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.
Negative contactor is expected to be open but the voltage match remains. Possible weld detected.
Contactor state timed out of OPENING (and transitioned to AUX_MISMATCH) due to a weld not having been disqualified.
The pyro fuse may be deployed.
Positive contactor is expected to be open but the voltage match remains. Possible weld detected.
Contactor state timed out of OPENING (and transitioned to AUX_MISMATCH) due to a weld not having been disqualified.
The pyro fuse may be deployed.
Negative contactor is expected to be open but aux reports them as still closed.
Contactor state timed out of the OPENING state (and transitioned to AUX_MISMATCH) due to aux reporting the contactor as still closed.
Firmware will try to open the contactor again.
Positive contactor is expected to be open but aux reports them as still closed.
Contactor state timed out of the OPENING state (and transitioned to AUX_MISMATCH) due to aux reporting the contactor as still closed.
Firmware will try to open the contactor again.
Negative contactor was blocked from opening due to high current. Pyro deployed instead.
High voltage current is too high while attempting to open the contactor.
The negative pyro fuse will be deployed.
Positive contactor was blocked from opening due to high current. Pyro deployed instead.
High voltage current is too high while attempting to open the contactor.
The positive pyro fuse will be deployed.
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.
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.
