$35 Electric Power Steering with Fail-Safe - No eBay module and no caster issues!!!

Hi all, I have a Yaris EPS with his ECU and I am not able to bring it to life .I do not know if the EPS comes from a ABS version.
When I put 12 v on pin 6 the ECU clicks twice and nothing happens when I turn the steering wheel.
What can I do with pin 5 ? I tried to put a 12v signal on it ...nothing, tried to put a pulse signal from a hall sensor ...nothing
The strange thing is that when I cut the 12v signal on pin 6 the ECU clicks but continue to draw some current from the battery and if I disconnect the battery on main power wire the ECU clicks again...
Many thanks in advance for your expertise
