The Compressor (CMPT) High Voltage Interlock Loop (HVIL) status signal is not reporting to the High Voltage Battery (HVBATT) on the Controller Area Network (CAN).
The CMPT HVIL status signal is not received by HVBATT within its message cycle time.
Vehicle may be unable to enter drive and may be unable to charge.
The Compressor (CMPT) High Voltage Interlock Loop (HVIL) is reporting as unknown, breaking the overall High Voltage Battery (HVBATT) HVIL.
The CMPT HVIL is reported as unknown.
Vehicle may be unable to enter drive and may be unable to charge.
High voltage isolation dropped under threshold in many drive sessions
Isolation or isolation degradation alert is set many times
Vehicle will be unable to restart
Sets immediately on SPI comms errors for visibility into the health of the comms interface

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.
