• Enter PoM mode on your DCC handheld and write a value of 55
to CV55. Again, even though your MTH engine is NOT on address
55 it will still listen for this reset command
• Call up address 3 on your DCC handheld and hit F3. The engine
should now start-up
If you have performed the 55-55-55 reset and the engine still doesn't respond
then place the engine on the programming track output of your DCC system
and program a value of 3 to CV1. This will set the engine's short address to 3.
However, as long as the engine is NOT programmed as address 55 then the
55-55-55 reset will always set the engine's long and short addresses back to
their factory defaults. It will also set the engine's addressing back to short (if
you happened to have CV29 set to long addressing)
The 55-55-55 Reset can be confusing at first but the main point to note is that
you are NOT setting the engine's address to 55 to perform the reset, you are
just calling up engine address 55 on your DCC handheld and sending a value
of 55 to CV55. Again, MTH engine's will listen to the 55-55-55 reset
command even though the engine's address isn't actually 55 (and it can't be
for the 55-55-55 reset to work).
