|
No
|
|
|
The low voltage battery management system (LVBMS) reports the low voltage (LV) battery has a reduced state of charge (SOC), which may lead to the LVBMS opening the LV battery internal protection transistor (MOSFET).
|
The LVBMS detects the LV battery SOC is below 15% for 5 seconds.
|
The LV battery may be unable to support vehicle electrical systems.
|
No
|
|
|
The vehicle controller detects a refrigerant condition, such as low refrigerant or a blocked refrigerator filter, which may prevent the A/C compressor from operating as expected due to high suction superheat if no other heat pump modes are available.
|
The vehicle controller detects low refrigerant, a blocked refrigerant filter, or other refrigerant related conditions on the A/C compressor.

|
No
|
|
|
The front vehicle controller has detected a problem during an eFuse self-test
|
Voltage conditions during the self-test sequence are not met.

An eFuse may be unable to turn off or on. Front vehicle controller (VCFRONT) may not function as expected.
|
No
|
|
|
The Low Voltage Battery Management System (LVBMS) detects high temperature at the low voltage (LV) battery MOSFET (internal protection transistor).
|
The LVBMS MOSFET temperature has reached 100 deg C for 1 second.
|
The low voltage (LV) battery may show degraded performance or become unavailable due to high temperatures.
|
No
|
|
|
The low voltage battery management system (LVBMS) reports it has detected a low voltage (LV) battery cell voltage imbalance and is attempting to rebalance the cell voltages. The vehicle will be kept awake to support the LV battery until the rebalancing attempt is complete.
|
The LVBMS detects that all LV battery cell voltages are not within 100mV of each other.
|
The LV battery may suddenly become unavailable and unable to support vehicle electrical systems. The LV battery may require replacement, and a separate alert should be present to indicate this condition if applicable.
|
No
|
|
|
The front vehicle controller (VCFRONT) detects an eFuse overcurrent event (or a trip) on the left headlight power feed.
|
The VCFRONT detects an eFuse overcurrent event on the left headlight power feed.
|
The left headlight may be unavailable or may not function as expected.
|
No
|
|
|
The vehicle controller is loadshedding due to a vehicle collision. Make sure the vehicle is safe to re-energize before using the Clear Post-Crash Loadshedding (PROC_VCFRONT_X_CLEAR-POST-CRASH-LOADSHEDDING) routine to resume all low voltage electrical system features and enable high voltage system again.
|
Vehicle collision is detected.
|
High voltage system is unavailable. Low voltage electrical system features are limited to conserve energy for essential functions.
|
No
|
|
|
One or more of the messages the vehicle controller receives periodically from the right second row seat controller (VCSEAT2R) is not received, indicating the VCSEAT2R may be unavailable (MIA).
|
The vehicle controller does not receive one or more of the expected messages from the VCSEAT2R within the expected time frame.
|
Vehicle functions that depend on the VCSEAT2R may be unavailable or may not function as expected.
|
No
|
|
|
A condition affecting left low beam (dipped beam) or high beam (main beam) functionality has been detected - the left low beam or high beam may be degraded or disabled.
|
An internal condition affecting the low beam (dipped beam) or high beam (main beam) LEDs, pixels, or the headlamp ECU's LED drivers is detected.
|
Left low beam (dipped beam) or high beam (main beam) may be partially or fully disabled.
|
No
|
|
|
The low voltage (LV) battery is discharging, even though high voltage (HV) system support has been requested. Vehicle loadshedding will occur, and a separate alert will be present to indicate that condition.
|
LV battery is being discharged, even though the HV system should be supporting both the LV battery and the LV bus.
|
Vehicle loadshedding is triggered, and a separate alert will be present to indicate that condition and its impacts.
|
No
|
|
|
The Low Voltage Battery Management System (LVBMS) detects that the low voltage (LV) battery pack is experiencing high temperatures.
|
