An other strip to float fuel level question

[de walque]

Hello to all of you, and thanks for your time
So on this bike gs1200adv 2010 i did change the fuel strip level to the float type
Did change two pin on one connector to the zfe module  (a high one )
With my gs tool i try to code the zfe module, but it say turn off the switch and wait. 
a bar graph  will appear... but nothing will happen
i will shot a error like a server fault...
did try it 4 or five time always same result
Do some one have an idea?
Here the vin of the bike:   zy04840
Thanks again
