|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
