Hi again,
Please have a read of this Topic, where the same problem was discussed :
Fuel gauge shows 0 bars and Miles to Empty shows 0 milesThere are two potential solutions for you.
The first is, after ensuring the Main Battery is fully charged and in Good Condition
to disconnect the Battery, leave it disconnected for half an hour or so
to ensure all circuits have fully shut down and discharged, then reconnect it.
That has been found by some Members to cure some electronic "gremlins" caused by low battery voltage.
It could be however, that your Fuel Level Sender
is faulty -
The above topic gives details of some electrical tests that can be performed,
but the second option might need the Fuel Level Sender Unit to be replaced.
I'm not sure what you mean by : "....after fixing it needs to be cleared by an ECM" ?
Most DTC's are retained in the ECM Memory until the fault has been fixed.
They can then
either be erased directly using Diagnostic equipment connected to the Trophy,
such as by the Dealer, or after market equipment and software such as
DealerTool or TigerTool,
which will extinguish the MIL Light,
or the MIL Light will extinguish after there have been
3 "No Fault" start ups, ad the DTC will be erased from Memory after 40 "No Fault" start ups.
You may find that after completing the Battery disconnection as above,
that your MIL Light and DTC's will be resolved without further intervention.
However :
In light of the software version on your Trophy I would strongly suspect,
with fingers crossed, that these DTC's were generated as a result of low battery voltage,
and you
MUST get the software updated as a priority.

In the meantime I would pull the Fuse for the Audio system to prevent any further Battery drainage
that could leave you stranded - On my Trophy it's Fuse No.3 ( 10A ) of the forward Fusebox
behind the left Side Panel - the one with the little Music note symbol.
If the Dealer you bought the Trophy from was an official Triumph Dealership,
then they should have known about the Audio Software update,
and especially after having had to fit a new battery, should have investigated,
found the outdated software and updated it before selling it to you.
You would have a good case for asking them, as a minimum, to update it free of charge,
and if the latest Battery has been affected by being drained again, to replace it again - on their dime !
Several Members have reported their US dealers being unable to locate
the Software update files on their systems !

- This Topic explains where to find it ! :
Where Triumph dealers can find audio software updates (U.S.)If you have any problems getting the Dealer to do this, or they want to charge
a stupid amount of $$$'s, send me a Private Message and I can give you further information.
Cheers
