What does VCFRONT-A463 mean?
Tesla alert code in the Vehicle Controller Front (VCFRONT) module. Frunk sensor requires servicing Both switches are pressed, both switches are unpressed, or any switch is shorted/disconnected Frunk latch switches are in expected range Frunk behavior may be less optimized An issue with the low voltage (LV) electrical system requires the vehicle to come to a stop immediately. The vehicle should enter graceful power-off (GPO) to exit drive, and a separate alert should indicate that condition. Low voltage (LV) battery voltage below 10.8V for 3 seconds (3s). Low voltage (LV) battery voltage above 10.8V. The vehicle will not enter drive. If the vehicle is driving, it will exit drive through graceful power-off (GPO) to come to a stop immediately. A separate alert should be present to indicate the GPO Data gathering alert for turn stalk usage
