Suddenly, my DCS remote can not find an engine. Even though the engine is in the list, the remote can not find it. I tried add engine,edit engine, reset engine, recover engine and nothing works. Tried multiple engines. Makes me think maybe the TIU is not working. The red power light is on. If a fuse were blown, would there be an indication? I do not know how to troubleshoot the TIU or remote. Remote seems to be functioning but nothing happens.
I am using a Z4000 and remote power for the TIU. The TIU is one of the originals but it is on version 6.10.
