Signal Name Description Condition Impact Important
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
Incorrect or missing IP address programmed.
Hvpack IP address may be missing, incorrect, or unsupported
Hvpack is unable to initialize network data
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
Subpack may not come online
No
The difference in pack voltage measurements of the ADC & BMBs exceeds the maximum limit.
The difference in ADC & BMB pack voltage is greater than 3%
The contactors may open immdediately or pyro disconnect may blow
No
A pack module temperature is above maximum temperature limit.
A pack module temperature is above maximum temperature limit for X duration (in seconds)
The conactors may open immdediately or pyro disconnect may blow
No
A brick voltage is below minimum voltage limit.
A brick voltage is below minimum voltage limit for X duration (in seconds)
The conactors may open immdediately or pyro disconnect may blow
No
A brick voltage is above maximum voltage limit.
A brick voltage is above maximum voltage limit
The contactors may open immediately or pyro disconnect may blow
No
Incorrect, missing, or unsupported board part number programmed.
HVPACK detects an unexpected board part number
HVPACK is unable to initialize parameters related to printed circuit board assembly (PCBA) configuration
No
The charge port (CP) electronic control unit (ECU) is detected as not operational, making the vehicle unable to charge.
The charge port (CP) electronic control unit (ECU) is detected as not operational.
Vehicle will be unable to charge.
No
