Alerts

The vehicle controller does not receive one or more of the expected messages from LVBMS within the expected time frame over the local interconnect network (LIN).

Vehicle functions that depend on the low voltage battery controllers may be unavailable or may not function as expected.

One or more loads did not turn off during the Left Domain Undervoltage self-test.

Impacted load(s) can not be turned off. This alert is primarily informational and is used for logging purposes.

BMS_packCurrent is less than -BMS_maxDischargeCurrent by too much for too long

BMS will exit the HV_UP state

An invalid pack SN has been read

Pack data will not be tracked in NVM. Pack vitals, such as State of Charge, may be inaccurate after ECU resets

Cabin HVAC right airwave vertical actuator reports a condition affecting functionality.

Cabin heating and cooling (HVAC / climate control) may be unavailable.

The operating time has exceeded 90 seconds within 5 minutes

The seat track motor will be disabled if operation is continued and exceeds 120 seconds within 5 minutes

Force sensor calibration is invalid

Loss of functionality due to system failure

Left airwave vertical actuator detected a fault (check context data for type of fault)

The heater and the A/C and heater may be disabled

Left airwave vertical actuator is not calibrated

The airwave control may be disabled

Left airwave lateral actuator detected a fault (check context data for type of fault)

The heater and the A/C and heater may be disabled

front exterior handle current sense is at 5V

front exterior handle temporarily unavailable

Cabin HVAC left airwave vertical actuator reports a condition affecting functionality.

Cabin heating and cooling (HVAC / climate control) may be unavailable.

Cabin HVAC left airwave lateral actuator is not calibrated.

Cabin HVAC airwave control may be unavailable.

Left airwave lateral actuator detected a fault (check context data for type of fault)

The heater and the A/C and heater may be disabled

The LVBMS detects a condition affecting its ability to manage the LV battery. Alert log signal data should provide more information.

Lack of LVBMS functionality may result in LV battery damage or degradation, and may also result in loss of LV battery support for vehicle electrical systems.

Single and mutual capacitive values are not matched to expected use cases (deltas are not matched)

Loss of functionality due to functional safety checks

An unsupported battery type is installed

BMS firmware does not support the desired battery type and will not operate

The LVBMS reports to the vehicle controller that the LV battery is not recoverable due to any of the following conditions: depleted LV battery state of charge (SoC) due to deep discharge; one or more cell voltage(s) at less than its threshold; the sum of all cell voltages is less than its threshold.

The LV battery is not recoverable by any device.

The front overhead console is unplugged or is not responding

Backup gear shifter is not functional

A valid pack SN has been read with does not match the pack SN associated with the NVM data used after ECU reset

The NVM data used during initialization may not match with the swapped pack. Pack vitals, such as State of Charge, may be inaccurate
