| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The HvSense measurement asic has a SPI communication fault or other internal fault.
|
Fault condition was set during SPI communications
|
HvSense readings are stale
|
|
|
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 will stop charging.
|
|
|
Positive contactor opened unexpectedly due to insufficient coil drive current.
|
Contactor state exited ECONOMIZED because coil current was too low.
|
Vehicle will stop charging.
|
|
|
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 FC 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 FC 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 FC 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 FC 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 FC 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 FC contactor will remain open.
|
|
|
FC contactor opened unexpectedly due to insufficient contactor drive voltage.
|
Contactor control state exited CLOSED because of insufficient contactor power voltage.
|
Vehicle will stop charging.
|
|
|
FC contactor exited the economized state unexpectedly. Possibly insufficient coil drive current.
|
Contactor control state exited CLOSED because either of the contactors exited ECONOMIZED.
|
Vehicle will stop charging.
|
|
|
Tried to close FC contactors but failed because a voltage match was not maintained.
|
Contactor control state exited CLOSING due to voltage match being lost.
|
FC contactors will remain open.
|
|
|
FC contactors were blocked from opening due to high current. Pyro deployed instead.
|
Charge current is above threshold while trying to open FC contactors.
|
The positive and negative pyro fuses will be deployed.
|
|
|
Indicates valid data is missing for one or more brick voltages.
|
One or more brick voltages are continuously detected as invalid
|
Brick voltage data is likely being substituted to replace invalid readings
|
|
|
The shunt measurement asic has a SPI communication fault or other internal fault.
|
Fault condition was set during SPI communications
|
Shunt readings are stale
|
|
|
Pyro fuse deployment was triggered by firmware but did not successfully execute.
|
Pyro fuse deployment was recently triggered and the deployment failed.
|
Pyro deployment may be compromised.
|
|
|
Pyro fuse deployment was triggered by firmware.
|
Pyro fuse deployment was triggered by firmware.
|
Fast Charge (FC) link is offline and DC link is split.
