    2. Using the joystick, select Current Faults (if the fault is active) or Aircraft History to research stored faults. From Aircraft History you can then select Fault Message History and locate the air condition fault logged.
    3. Select the MDC fault from the drop down below to provide additional information to assist in troubleshooting.
