VCFRONT-A349
VCFRONT_a349_vbatFusedFastTripSlope
What does VCFRONT-A349 mean?
Tesla alert code in the Vehicle Controller Front (VCFRONT) module. The front vehicle controller fused high current circuit eFuse reported a current slope > 120A/ms. The MCU Audio eFuse was retried because it false tripped due to inrush. There is a >3% difference between VBAT_MONITORS's reported voltage and the AS8510 chip's reported voltage. There is >3% difference between VBAT_MONITORS's reported voltage and the AS8510 chip's reported voltage. There is <3% difference between VBAT_MONITORS's reported voltage and the AS8510 chip's reported voltage. Improper treatment of the 12V battery, vehicle LV bus voltage could be higher or lower than is desired.
