$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

Is the column mounted or testing it in the bench? If testing on the bench, you have to lock the output shaft in a vice. If the torque sensor doesn't get any resistance, it won't actuate the motor.
