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
|

|
|
|
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.
|
|
