|
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.
