What does MCU-W012 mean?
Tesla warning code in the Media Control Unit (MCU) module. This alert indicates that the tire pressure monitor system (TPMS) electronic control unit (ECU) cannot read one of the sensors or has detected that there is an issue internal to the ECU. If this alert is present, a sensor signal may have dropped out, but the alert only indicates that the ECU is in a fault state and cannot reliably report tire pressures or produce the appropriate pressure-related warnings.
