This alert indicates that the shunt bar temperature is above what is nominally expected, which can be indicative of issues in the penthouse like 3rd party pyros or improperly installed HV components.
|
The shunt bar's temperature is above the set threshold during drive
|
The output power during drive may be reduced. If a 3rd party pyro is installed or some component in the penthouse is improperly installed, devices in the HV chain may experience additional wear caused by experiencing higher temperatures.

|
The battery management system (BMS) receives a request from the high voltage processor (HVP) to initiate a graceful power off (GPO).
|
The battery management system (BMS) receives a request from the high voltage processor (HVP) to initiate a graceful power off (GPO).
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected an uncontrolled regen event in track mode.

|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The Battery Management System (BMS) energy buffer is greater than the acceptable threshold. This results in an inaccurate range estimate.
|
The BMS energy buffer is greater than the acceptable threshold.
|
A large energy buffer results in an inaccurate battery State of Charge (SOC) estimation causing a poor range estimate.
|
No
|
|
|
A graceful power (GPO) off has been activated by the battery management system (BMS).
|
The BMS detects a condition that requires it to start GPO.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
Battery management system (BMS) detects a condition while charging likely caused by the EVSE / external charging equipment. The BMS stops charging and prevents retries while the charging equipment is connected.
|
The BMS detects an issue during charging likely caused by the EVSE / external charging equipment
|
The vehicle will not charge while this alert is set
|
No
|
|
|
The battery management system (BMS) has encountered an issue while charging or attempting to charge.
|
The BMS detects a condition that prevents it from starting charging.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has detected an issue with brick voltage measurement.
|
The BMS detects a mismatch between a stack's voltage and the sum of its brick voltages.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) has reduced power for driving.
|
The BMS detects a condition that requires it to put the vehicle in limp mode.
|
Power is reduced.
|
No
|
|
|
The battery management system (BMS) detects that one DC (pack) and one FC contactor are welded.
|
The BMS detects that one DC (pack) and one FC contactor are welded.
|
This alert is primarily informational.
|
No
|
|
|
The battery management system (BMS) detects that both of the FC Link contactors are welded.
|
The BMS detects that both of the FC link contactors are welded.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) detects that one of the FC link contactors is welded.
|
The BMS detects that one of the FC link contactors is welded.
|
This alert is primarily informational.
|
No
|
|
|
The battery management system (BMS) detects that both of the pack contactors are welded.
|
The BMS detects that both of the pack contactors are welded.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) does not have enough power to provide low voltage (LV) support.
|
The BMS detects that the high voltage (HV) state of charge (SOC) is too low to support the LV system.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The High Voltage Processor (HVP) error pin is asserted on Battery Management System (BMS) input.
|
Analog input pin from the HVP is raised pointing to the HVP Error line being asserted.
|
There is a temporary loss of High Voltage (HV) functions.
|
No
|
|
|
The battery management system (BMS) reports a communication issue with the high voltage processor (HVP).
|
The BMS is not receiving the expected messages from the HV system.
|
Inability to charge, drive, or support the low voltage (LV) system
|
No
|
|
|
The battery management system (BMS) detects an out-of-bounds module voltage reference.
|
Any battery monitoring board (BMB) reference voltage has continuously deviated outside the in-bounds threshold of the nominal voltage.
|
This alert is primarily informational. Other BMB voltage signals will be substituted given the reference voltage is unreliable.
|
No
|
|
|
The battery management system (BMS) detects that high voltage (HV) isolation is too low while pack contactors are closed.
|
The BMS has detects that HV isolation is below the warning threshold while contactors are closed.
