EFIS TFC Button

The TFC button on my EFIS does not respond in the sim (PMDG MSFS.) Is there a way I can trobleshoot?

You can go to the DEVICE TEST page in the Bridge software and test the EFIS TFC button to see if it works.

Thank you support for your response. I finally did go to the Test Page and all my knobs and and buttons function as they turn green on the test page. The TFC push button does not respond. What can I do?
