What does VCFRONT-A134 mean?
Tesla alert code in the Vehicle Controller Front (VCFRONT) module. The VBAT Fused High Current eFuse has faulted. HVAC cabin cooling (air conditioning) and powertrain performance may be limited. No power to the coolant pumps and condenser fan. A fault is reported by the VBAT Fused High Current eFuse circuitry. A fault is no longer reported by the VBAT Fused High Current eFuse circuitry. The pumps and condenser fan will no longer work, the PCS might overheat. HVAC cabin cooling (air conditioning) and powertrain performance may be limited. The coolant level sensor is reporting that the coolant is not filled. Powertrain performance may be limited. Unexpected fault in a VNF1048 chip The recirc EXV's motor driver has reported a warning.
