VCFRONT1_a496 — Exit Drive Warning Domain Down
Full alert identifier: VCFRONT1_a496_exitDriveWarningDomainDown
Message shown in the car
Vehicle is preparing to shut down PULL OVER SAFELY
Alert description
The Low Voltage (LV) battery domain is in a critical state, and the vehicle controller is triggering a graceful exit from drive or graceful power-off (GPO). One or more alerts will be present when the vehicle starts the GPO.
Potential impact
The vehicle will exit drive within the next few minutes. A separate alert will be present to indicate that condition, and the next drive cycle will be blocked.
Set condition
May set due to a condition or combination of conditions indicating the LV battery cannot support the vehicle, including: the LV battery internal protection transistor (MOSFET) is open, the reverse battery eFuse has tripped (is open), or the vehicle controller is actively shedding vehicle electrical loads to conserve energy for essential functions. Alert log signal data should provide more information.
Clear condition
No condition or combination of conditions is detected indicating the LV battery cannot support the vehicle, or the vehicle has already entered graceful power-off (GPO) and is actively exiting drive.
