|
Incorrect battery current data being used, resulting in sub-optimal LV battery management.
|
|
|
The vehicle controller detects the supply voltage from 1 or more components is outside of the expected range.
|
The vehicle controller detects the supply voltage from 1 or more components is < 7.31. Alert log signal data should provide more information on the specific condition(s) detected.
|
Features depending on the vehicle controller functionality may be unavailable or may not function as expected.
|
|
|
The vehicle controller (VC) identified the PCS is MIA and may be in need of a power cycle to be recovered. This alert indicates the low voltage (LV) battery is in good state to support this.
|
The PCS is MIA when expected to be active on CAN, the LV battery is connected, the vehicle is not in service mode, and the vehicle is not being updated.
|
The PCS may be power cycled by the high voltage system.
|
|
|
A condition affecting left front turn signal functionality has been detected - the left front turn signal may be degraded or disabled, and remaining left side turn signals will fast blink.
|
The headlamp ECU is MIA on LIN (not responding to Local Interconnect Network traffic) while powered on, or an internal condition with the turn signal LEDs or the headlamp ECU's LED driver is detected.
|
Left side turn signals will fast blink
|
|
|
The Low Voltage Battery Management System (LVBMS) detects that the low voltage (LV) battery pack is experiencing high temperatures.
|
The LVBMS module temperature has reached 60 deg C for 1 second.
|
The low voltage (LV) battery may show degraded performance or become unavailable due to high temperatures.
|
|
|
A condition affecting left daytime running light (DRL) functionality has been detected - the left daytime running light may be degraded or disabled.
|
An internal condition with the daytime running light (DRL) LEDs or the headlamp ECU's LED driver is detected.
|
Left daytime running light (DRL) may be partially or fully disabled
|
|
|
The vehicle battery controller (VCBATT) detects an eFuse overcurrent event (or a trip) on the left headlight power feed.
|
The VCBATT detects an eFuse overcurrent event on the left headlight power feed.
|
The left headlight may be unavailable or may not function as expected.
|
|
|
An issue is indicated from the non-volatile memory manager.
|
Non-volatile memory misconfiguration or underlying flash/filesystem error.
|
Non-volatile memory records may be incorrect or missing.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
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.
|
|
|
The low voltage (LV) battery type detected on startup is unknown. This usually happens the first time a controller is powered on, or after non-volatile memory (NVM) corruption, which will be indicated by another alert.
|
The LV battery type detected on startup is unknown.
|
LV battery performance may be limited. LV battery support for vehicle electrical systems may be limited or unavailable.
|
|
|
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.
|
|
|
The Low Voltage Battery Management System (LVBMS) detects high temperature at the low voltage (LV) battery MOSFET (internal protection transistor).
