| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The positive (left) junction box lid switch is reporting as unknown, breaking High Voltage DC Link Controller (HVLINK) High Voltage Interlock Loop (HVIL).
|
Positive (left) junction box lid switch reported as unknown.
|
DC Link may discharge or fail to energize.
|
|
|
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.
|
|
|
Warns if the pack current (discharge or charge) is above max current limit.
|
The pack current (discharge or charge) is above max current limit.
|
The pyro disconnect will blow
|
|
|
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.
|
|
|
Incorrect or missing IP address programmed.
|
Hvpack IP address may be missing, incorrect, or unsupported
|
Hvpack is unable to initialize network data
|
|
|
Incorrect or missing MAC address programmed.
|
Hvpack MAC address may be missing, incorrect, or unsupported
|
Hvpack is unable to initialize network data
|
|
|
High voltage isolation is too low for the pack to be online.
|
Isolation is measured to be below the alert threshold while pack contactors are closed
|
Subpack may not come online
|
|
|
Shunt thermistor is not connected.
|
Shunt thermistor reading is open-circuit
|
Subpack may not come online
|
|
|
Subpack measurement of internal isolation (within the subpack) is too low.
|
Internal isolation is measured to be below the alert threshold
|
Subpack may not come online
|
|
|
The difference in pack voltage measurements of the ADC & BMBs exceeds the maximum limit.
|
The difference in ADC & BMB pack voltage is greater than 3%
|
The contactors may open immdediately or pyro disconnect may blow
|
|
|
A pack module temperature is above maximum temperature limit.
|
A pack module temperature is above maximum temperature limit for X duration (in seconds)
|
The conactors may open immdediately or pyro disconnect may blow
|
|
|
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
|
|
|
A brick voltage is below minimum voltage limit.
