Ok, now we know it’s a beginning TMCC version of Command. My suggestion is to program this engine with the first two digits of the cab number. Example, if the number was 1995, use 19. With power on, 18 volts, Turn your run program switch to program, then press the ID number and press set. The Horn should blow. Turn off the track power, wait 10 seconds, turn the program switch to run. Now turn the track power on. Press the remote to the ID number and then press aux 1. Your engine should start up. In your instructions should be an example of the Cab 1 button functions. You should then be able to raise and lower the Diesel sounds. Each number has a function. There should also be a clear plastic insert that is square and fits over the Cab 1 keys. They are easy to read. If all else fails, go to your local hobby shop for friendly good help. Good luck.
I hope you understand that Command is 18 volts to the track all the time. Conventional is transformer controlled. When 18 volts are on the track, your red knob controls the speed and to make the layout in command mode, you press the Cab-1 then the L button at the bottom of the remote to power up the track. So, this might be part of the issue. Good luck.
