Hi 
I have check all fuse is ok

Can you communicate with engine ecu? What is status of terminal 15 in EIS and SAM ecu?

yes engine écu com ok 
ezs com ok 
will check status of 15 in ezs and sam but 15 in sam not have cause some fuse of gearbox and another élément supply to the terminal 15 0v

ecu not communication is gearbox

thanks

If the fuse is ok, then measure if you have Circuit 15 (12v) there, if not, then locate Circuit 15 relay "R"
and measure Circuit 30 (12v) on leg "30" and 12v on leg "86" from SAM.
If this Circuit 15 Relay "R" is not not working a lot of electronics would not work.

Hi and
Thanks friend for you great help   
Have 0 v in plug gearbox right ( gearbox  is supply by terminal 15 …terminal 15 supply « fan » too right but same 0 volt to small wire in fan motor….for that it’s terminal 15 problem all component supply with terminal 15 = 0 v 
that car put me crazy…fuse + relay on sam for gearbox = 0 v not power… 
Circuit 15 relay R ( K) find not power same :/

Great thanks again for you great help
Best Regards
