What does VCFRONT-A179 mean?
Tesla alert code in the Vehicle Controller Front (VCFRONT) module. High low voltage current into the PCS was detected when not precharging the high voltage bus. Current higher than 5 amps detected for more than 1 second. Vehicle re-attempts to close contactors and current is not higher than 5 amps detected for more than 1 second. PCS will not be supplied with low voltage power. The front controller was not able to go to sleep because a UI keep awake reason was triggered.
