Troubleshooting Recommendations:

  1. Interrogate the MDC as follows:

    1. On the cursor control panel, ensure the toggle switch is to the right and select Anti-Ice, ECS and Fuel buttons simultaneously. The MDC main menu should now be displayed on Display Unit #3.
    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 History and locate the fault. Going into advanced diagnostics will provide an Equation ID for the fault identified.
    3. Select the MDC fault or Equation ID from the drop down below to get additional information to assist in troubleshooting.
