|
Battery subpack 1 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.
|
|
|
Battery subpack 1 pyro fuse deployment was recently triggered and the deployment test failed, indicating that it may not have deployed properly.
|
Pyro fuse deployment was recently triggered and the test failed.
|
Pyro deployment may be compromised.
|
|
|
A fault condition has been detected on the battery subpack 1 pyro fuse.
|
Leak test failure, switch test failure, or other failure.
|
Pyro deployment ability is compromised.
|
|
|
Battery subpack 1 pyro squib is disconnected or open-circuit, but pyro circuit is otherwise nominal.
|
Pyro squib is missing resulting in open-circuit resistance.
|
Pyro fuse deployment ability is compromised.
|
|
|

|
|
|
The High Voltage DC Link Controller (HVLINK) has detected a fault condition impacting the pyro subsystem.
|
A fault condition is detected by the pyro subsystem.
|
Pyro cannot be deployed.
|
|
|
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.
|
|
|
The High Voltage DC Link Controller (HVLINK) has detected a failure condition on the energy-reserve circuit.
