What does VCFRONT-A235 mean?
Tesla alert code in the Vehicle Controller Front (VCFRONT) module. The powertrain's coolant temperature sensor is reporting an incorrect value. Possible VCFRONT internal electrical issue. Powertrain performance may be limited. An irrational difference in the powertrain coolant temperature sensor values and the drive inverter's own temperature sensor values. Difference between the powertrain coolant temperature sensor value and the drive inverter temperature sensor values is nominal.
