|
No
|
|
|
The battery management system (BMS) detects that the high voltage (HV) isolation contactor closed below the warning threshold.
|
The BMS detects that the HV isolation was below the warning threshold when pack contactors closed.
|
This alert indicates that HV isolation is low, but above the sufficient level for vehicle operation.
|
No
|
|
|
The battery management system (BMS) has detected an issue with the low voltage (LV) power supply to the contactors.
|
The BMS detects that the input voltage from the LV system is too low.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected that there is a high voltage (HV) battery current sensor (shunt) error.
|
The BMS detects a HV battery current sensor (shunt) is unable to trip its over current fault line.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected a that there is an issue with the DC link voltage sensor.
|
The BMS detects that there is an issue with the DC link voltage sensor.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected that the voltage of one or more bricks is above the warning threshold.
|
The BMS detects that one or more bricks' voltage is above the warning threshold.
|
This alert is primarily informational and is used for logging purposes.
|
No
|
|
|
The battery management system (BMS) has detected that there is an over-discharged brick.
|
The BMS detects that the minimum brick voltage is below the 0% SOC OCV target while fully rested and with the contactors open.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected that a module is overheating.
|
A thermistor reports a module temperature above the acceptable range.
|
Power is reduced.
|
No
|
|
|
A software tool (such as Toolbox) connected to the vehicle requests an action from the battery management system (BMS) that is either improperly requested or is not permitted in the current BMS state.
|
A software tool improperly requests an action from the BMS or requests an action that is not permitted.
|
The requested diagnostic function is not performed.
|
No
|
|

No
|
|
|
The battery management system (BMS) has detected an issue with the voltage sensor harness (VSH) connector on the battery monitoring board (BMB).
|
The BMS detects that the impedance of the VSH connector is above the limit threshold.
