|
No
|
|
|
A Red Green Blue (RGB) light error has been detected.
|
A condition affecting RGB light communication or functionality is detected. Alert log signal data should provide more information on the specific condition and RGB light affected.
|
RGB light may be unavailable or may not function as expected.
|
No
|
|
|
The low voltage battery management system (LVBMS) reports it has detected a low voltage (LV) battery cell voltage imbalance.
|
The LVBMS detects that all LV battery cell voltages are not within 150mV 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 low voltage (LV) battery is not communicating as expected, indicating a potential disconnection with the vehicle controller.
|
Electronic connector position assurance (ECPA) state is signal not available (SNA), or the intelligent battery sensor (IBS) is not functioning as expected and the low voltage battery management system (LVBMS) is not communicating (MIA).
|
Loss of low voltage (LV) battery communication with vehicle controller, so the vehicle electrical system may only be supported via the power conversion system (PCS).
|
No
|
|
|
The low voltage (LV) battery type detected on startup does not match the LV battery type reported by the vehicle gateway (GTW) configuration.
|
The LV battery type detected on startup does not match the LV battery type reported by the GTW configuration.
|
LV battery performance may be limited. LV battery support for vehicle electrical systems may be limited or unavailable.
|
No
|
|
|
An electrical error has been detected with the left fog light guide (white light pipe in front fascia that turns on along with fog light).
|
The high side driver (HSD) for the left fog light guide reports that an undercurrent or short circuit condition is present.
|
The left fog light guide may not be working.
|
No
|
|
|
The low voltage battery management system (LVBMS) reports it has detected the charge current is above the maximum limit for the low voltage (LV) battery cells in their present condition.
|
The LVBMS detects the charge current is above the maximum limit for the LV battery cells in their present condition for 1 second.
|
Exceeding charge current limits may shorten the life of LV battery cells, leading to accelerated degradation and replacement.
|
No
|
|
|
Vehicle will enter deep sleep to conserve energy in 10 minutes. It is possible to wake the vehicle up within the next 10 minutes by pressing the trunk button or applying external voltage to the front trunk (frunk) access posts.
|
The vehicle is in Transport Mode and the high voltage (HV) battery state of charge (SOC) is low.
|
Vehicle will only wake from deep sleep via a trunk button press or when external voltage is applied to the frunk access posts.
|
No
|
|
|
The electrical current flowing through the left vehicle controller (VCLEFT) eFuse is greater or equal to 100A. The VCLEFT eFuse circuit may open (trip) if the low voltage (LV) electrical system loads are not reduced. The vehicle controller requests the VCLEFT to shed vehicle electrical loads by cutting power to the less essential loads.
|
The VCLEFT eFuse current value equals or exceeds 100A for 100 milliseconds.
|
Some convenience features controlled by the VCLEFT will be unavailable as the vehicle controller limits the LV electrical system current draw by cutting power to some loads.
|
No
|
|
|
Warns if the processor has experienced a reset due to power loss.
|
Sudden power loss.
|
Controller is MIA for some time.
|
No
|
|
|
The eFuse application-specific integrated circuit (ASIC) on the vehicle controller has incorrect thresholds set.
|
The vehicle controller detects incorrect threshold values on its eFuse ASIC for 1 second.
|
The eFuse ASIC on the vehicle controller may not function as expected.
|
No
|
|
|
The vehicle controller has disabled communications over the bus that connects to the low voltage (LV) battery after detecting a condition (or conditions) that may cause the LV battery to become overdischarged. To avoid overdischarge that could make the LV battery unrecoverable, do not restore communications until the LV system is fully supported by the Power Conversion System (PCS).
|
The vehicle controller detects the LV battery may become overdischarged unless it sleeps, and also determines vehicle conditions are OK to disable LV battery communications.
|
The vehicle controller will have less information about the LV battery until it is serviced. Headlamps and windshield wipers may be unavailable, or may not function as expected.
|
No
|
|
|
The low voltage battery management system (LVBMS) reports it has opened the low voltage (LV) battery internal protection transistor (MOSFET) after detecting a cell overvoltage condition.
|
The LVBMS detects a cell overvoltage condition affecting the LV battery.
|
The LV battery may be damaged and may be unable to support vehicle electrical systems.
|
No
|

|
One or more of the expected messages from the VCSEATP is not received.
|
Front passenger seat features depending on VCSEATP functionality, including seat buckle and heating pad, may be limited or unavailable.
