Warns if the ENS line is not connected to HVC
|
The ENS line is not connected to HVC
|
The crash signal may not be detected by HVP
|
No
|
|
|
Warns if the pack voltage doesn't match approximately with sum of brick voltages
|
The pack voltage doesn't match approximately with sum of brick voltages
|
The contactors may not be allowed to close
|
No
|
|
|
Warns if the BMS node is mia on HVS CAN
|
The BMS node is mia on HVS CAN
|
CAN messages are not received from BMS or other nodes on vehicle
|
No
|
|
|
The High Voltage Processor (HVP) has detected a Fast Charge (FC) contactor has opened during a closed state.
|
The HVP has detected a voltage drop across the FC contactor, low contactor coil FC current, and the auxiliary switch is open. This indicates a FC contactor has opened despite being in a closed state.
|
The FC contactors will open. The vehicle may not be able to DC charge. The current charging session may be unexpectedly terminated as the FC contactors open.
|
No
|
|
|
The High Voltage Processor (HVP) has detected a pack contactor has opened during a closed state.
|
The HVP has detected a voltage drop across the contactor and low contactor coil current, indicating a pack contactor has opened despite being in a closed state.
|
The pack contactor state will appear as open. The vehicle powertrain may unexpectedly lose high voltage power under load.
|
No
|
|
|
The High Voltage Processor (HVP) has detected the Charge Port HV Interlock Loop (CPIL) has a condition affecting functionality.
|
The HVP General Purpose Input/Output (GPIO) input has detected the CPIL has a condition affecting functionality.
|
The Fast Charge (FC) link will not be allowed to charge. The vehicle may not charge as expected, or at all.
|
No
|
|
|
The High Voltage Processor (HVP) detects a series arc at the negative pack contactor.
|
The HVP detects a series arc at the negative pack contactor.
|
The pyro fuse may blow. The vehicle may be unable to drive or charge.
|
No
|
|
|
The High Voltage Processor (HVP) detects a series arc at the positive pack contactor.
|
The HVP detects a series arc at the positive pack contactor.
|
The pyro fuse may blow. The vehicle may be unable to drive or charge.
|
No
|
|
|
Sets if an HVIL fault is detected. Contactors cannot close (car will no longer drive) if the contactors are currently open. If no repairs were performed and the alert clears on its own, there is risk of reoccurrence.
|
The HVIL is broken or HVIL nodes are lower than expected
|
Contactors will not close, it may open if vehicle not in drive
|
No
|
|
|
Negative contactor opened unexpectedly due to insufficient coil drive current.
|
Contactor state exited ECONOMIZED because coil current was too low.
|
Vehicle will stop charging.
|
No

|
No
|
|
|
Incorrect or missing MAC address programmed.
|
Hvpack MAC address may be missing, incorrect, or unsupported
|
Hvpack is unable to initialize network data
|
No
|
|
|
High voltage isolation is too low for the pack to be online.
|
Isolation is measured to be below the alert threshold while pack contactors are closed
|
Subpack may not come online
|
No
|
|
|
Subpack measurement of internal isolation (within the subpack) is too low.
|
Internal isolation is measured to be below the alert threshold
