|
There was an implausible brick voltage change.
|
A brick voltage deviated by an implausible amount in-between sensor samples.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The maximum charge level of the battery is limited by one or more alerts.
|
One or more battery management system (BMS) alerts that reduce the maximum charge limit are set.
|
Maximum charge is reduced.
|
|
|
The maximum charge level of the high voltage (HV) battery is exceeded.
|
One or more battery management system (BMS) alerts that reduce the maximum charge limit are set, and the instantaneous charge level is higher than that limit.
|
Vehicle will not be able to charge if connected to a power source, as the reduced maximum HV battery charge level is exceeded.
|
|
|
The High Voltage Battery (HVBATT) detects the standby supply is stuck in the OFF state.
|
The standby supply voltage has been under the defined threshold for the defined timeout.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The High Voltage Battery (HVBATT) detects the standby supply is stuck in the on state.
|
The standby supply voltage has been above the defined threshold for more than the defined timeout.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The standby supply is unable to activate because no eligible power sources are available.
|
The standby supply output is requested but there are no subpacks available for use.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
HVBATT detects that the sum of brick voltages deviates from measured pack voltage.
|
HVBATT detects that the sum of brick voltages deviates from pack voltage by more than 5 percent.
|

|
|
|
The High Voltage Battery (HVBATT) detects the low-side (LS) flyback output voltage is below the operational threshold.
|
The output voltage of the LS flyback is less than the defined threshold for more than the defined timeout.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The High Voltage Battery (HVBATT) detects the high-side (HS) flyback output voltage is below the operational threshold.
|
The output voltage of the HS flyback is less than the defined threshold for more than the defined timeout.

This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
Shunt active sense current reading deviates from zero when contactors are open.
|
Contactors are open and shunt active sense reading is larger than acceptable margin
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
Shunt active sense and passive sense readings are not in agreement.
|
Shunt active sense and passive sense readings have a delta outside of the acceptable margin
|
Vehicle may not drive or charge.
|
|
|
Shunt bar temperature is too low.
|
Shunt bar temperature is too low
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
