Signal Name Description Condition Impact Important
The battery management system (BMS) detects that one of the pack contactors is welded.
The BMS detects that one of the pack contactors is welded.
This alert is primarily informational.
No

The battery management system (BMS) detects low isolation while DC charging
The BMS detects that isolation resistance on the high voltage (HV) bus has fallen below the acceptable threshold while the vehicle is DC charging
The vehicle will not charge until the charge cable is removed and the alert is cleared
No
The BMS has detected isolation failure conditions in several drive sessions
Isolation or isolation degradation alert is set in several drive sessions
Vehicle may be unable to restart
No
The battery management system (BMS) detects a mismatch between actual and commanded fast charge (FC) contactor set state.
High voltage processor (HVP) comms are ok and fast charge contactors were closed and fast charge contactors are now open / opening and BMS_fcContactorRequest has remained closed.
DC charging is terminated.
No
The battery management system (BMS) detects a pattern test failure on a battery monitoring board (BMB).
The BMS runs the BMB pattern diagnostics and detects a deviation from the expected results for any device in the chain.
This alert is primarily informational, and may indicate a potential BMB hardware failure.
No
The battery management system (BMS) detects that the charge port (CP) is missing (MIA).
The BMS has not received one or more expected CAN messages from the CP.
Inability to charge, drive, or support the low voltage (LV) system
No
The Battery Management System (BMS) detects a Force External Isolation Test (FEIM) is required but is blocked due to a condition on the vehicle.
The BMS detects the FEIM is blocked due to another condition on the vehicle. Alert log signal data should provide more information on the specific reason.
The vehicle may be unable to drive.
No
The battery management system (BMS) detects a missing, incorrect, or unsupported part number.
The BMS detects an unexpected part number.
The BMS is unable to initialize parameters related to printed circuit board assembly (PCBA) configuration.
No
The battery management system (BMS) detects a mismatch between the actual and commanded pack contactor set state.
High voltage processor (HVP) comms are OK and pack contactors were closed and pack contactors are now open / opening and BMS_packContactorRequest has remained closed.
Inability to charge, drive, or support the low voltage (LV) system
No
The battery management system (BMS) detects that there is low high voltage isolation when pack contactors are opened.
The BMS detects that isolation dropped below the minimum threshold when pack contactors were open.
Inability to charge, drive, or support the low voltage (LV) system
No
The battery management system (BMS) detects that there is a coolant flood in the high voltage battery.
The BMS detects that isolation dropped below the minimum threshold when pack contactors are open and the low coolant signal is active.
Inability to charge, drive, or support the low voltage (LV) system
No
The battery management system (BMS) was unable to close pack contactors.
The BMS detects a condition that prevents it from closing pack contactors.
Inability to charge, drive, or support the low voltage (LV) system
No
