No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
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.
|
No
|
|
|
Pyro fuse deployment was recently triggered and the deployment test failed, indicating that it may not have deployed properly.
|
Pyro fuse deployment test failed
|
Pyro deployment may be compromised
|
No
|
|
|
A crash event has occurred resulting in the potential deployment one or more High Voltage (HV) system pyro fuses.
|
The Restraint Control Module (RCM) reports a crash via 1kHz Emergency Notification Signal (ENS) tones.
|
All subpack pyro fuses will be deployed. Fast Charge (FC) pyro fuses may be deployed, and the vehicle may not drive or charge.
|
No
|
|
|
The HvSense measurement Application-specific Integrated Circuit (ASIC) has a Serial Peripheral Interface (SPI) communication fault or other internal fault.
|
Fault condition was set during SPI communications.
|
HvSense readings are stale.
|
No
|
|
|
The HvSense measurement Application-specific Integrated Circuit (ASIC) is not producing or communicating data.
|
A timeout has occurred on the expected communication from the ASIC.
|
HvSense readings are stale.
|
No
|
|
|
HV Up is blocked by HVLINK because HVIL is not good.
|
HVIL is not good and BMS requests that the DC Link be energized
|
DC Link may fail to energize
|
No
|
|
|
The High Voltage Battery Subpack 2 (HVPACK2) is not reporting to the High Voltage DC Link Controller (HVLINK) on the Controller Area Network (CAN).
|
HVPACK2_interlocks is not received by HVLINK within the MIA qualification time interval.
|
HVLINK shall assume HVPACK2_pyroTestResponse = 0.
|
No
|
|
|
The High Voltage Battery Subpack 1 (HVPACK1) is not reporting to the High Voltage DC Link Controller (HVLINK) on the Controller Area Network (CAN).
|
HVPACK1_interlocks is not received by HVLINK within the MIA qualification time interval.
|
HVLINK shall assume HVPACK1_pyroTestResponse = 0.
|
No
|
|
|
A crash event has occurred resulting in the potential deployment one or more High Voltage (HV) system pyro fuses.
|
The Restraint Control Module (RCM) reports a crash over CAN while Emergency Notification Signal (ENS) tones are absent.
|
All subpack pyro fuses will be deployed. Fast Charge (FC) pyro fuses may be deployed, and the vehicle may not drive or charge.
|
No
|
|
|
The DCLink bus is shorted, preventing the ability to precharge contactors.
|
The energy consumed by the precharge Integrated Circuit (IC) during a precharge event exceeds the maximum allowed precharge energy.
|
Precharging will be halted and the vehicle will be unable to precharge its contactors.
