L3 Lynx Problem

[Skymac]

I’ve got a message showing up for a Suppression Bus Fault. Transponder is working, although I know it is suppose to be connect to the GNS430, it also has a filter I believe to the KN64 DME. Looked at their manual but it didn’t leave me with much of an idea on what to look for.

It is also suppose to have the WiFi module installed but doesn’t appear to be working.

Your avionics shop didn’t set the unit up properly.

A likely suspect of mine but also it has been installed for 2 years, we just purchased the plane and neither myself or my A&P have a good working knowledge of the system, first one we have seen. So was just maybe hoping someone here may be familiar with the install. A good, close avionics shop isn’t that easy to come by.
