Any advice on how to fix this problem? Multiple engines both TMCC and Legacy do not respond to the ENG soft key on my CAB2. The SW and TR soft keys work fine. The Legacy system was completely removed from the layout and the CAB1 system was installed. All of the engines responded to the ENG soft key. Compressed air was used to blow out the keys of the CAB2. The CAB2 was opened and compressed air was liberally sprayed throughout. After reassembly, the TR and SW soft keys worked fine, but the ENG soft key continued to be problematic. When when going through the SET process, the engine does not respond with headlight or sound acknowledgement. With any combination of keys starting with the ENG soft key, there is absolutely not reaction or acknowledgement from the four engines tested (three TMCC and one Legacy which responded using CAB1). Thank you, Hank
