Vehicle functions that depend on the VCLEFT may be unavailable or may not function as expected.
|
|
|
One or more of the messages the vehicle controller receives periodically from the front vehicle controller (VCFRONT) is not received, indicating the VCFRONT may be unavailable (MIA).

Vehicle functions that depend on the VCFRONT may be unavailable or may not function as expected.
|
|
|
The vehicle controller detects a condition affecting the front left fog light.
|
The vehicle controller detects that the front left fog light high side driver (HSD) reports one of the following: (1) a current draw below the minimum threshold (open circuit); (2) a current draw above the maximum threshold (short circuit).
|
The front left fog light may not produce light or may not function as expected.
|
|
|
The ESP Valve may have tripped, the current reported by the eFuse is outside the bounds of what can be measured.
|
Too much current detected by the ESP Valve high side driver.
|
ESP may be disabled.
|
|
|
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 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 current measurement reported by the LV battery (LVBMS_packCurrent) does not match the current sensor on the vehicle controller LV battery feed (IBSCurrent).
|
The absolute value of current difference between LVBMS_packCurrent and IBSCurrent exceeds nominal expectations
|
Incorrect battery current data being used, resulting in sub-optimal LV battery management.
|
|
|
The low voltage (LV) battery type reported by the vehicle gateway (GTW) configuration is a battery type not supported by this controller / firmware.
|
The LV battery type indicated by the GTW configuration value is an LV battery type not supported by this controller / firmware.
|
The LV battery system will not be updated to support the new configuration reported by the GTW configuration value. LV battery performance may be limited. LV battery support for vehicle electrical systems may be limited or unavailable.
|
|
|
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 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.
|
|
|
The Low Voltage Battery Management System (LVBMS) detects that the low voltage (LV) battery pack is experiencing high temperatures.
