Hello everybody!

I have a NISSAN P02 truck (model QP02L20U). When the trucks is ON, automatically appears on display "PS TROUBLE 013". The PS contactor is not actuated, and the electric steer is not working. I did some verifications:

1) On the back, I disconnect the steer motor cables, and tested the steer motor with 30V conecting. The motor worked ok, without problem to the booth sides.
2) Check the potenciometer (steer sensor) cables on back. I disconnected the CN2 plug on the main controller, and then tested the poti values. Are ok!
3) I checked the PS contactor coil resistance value, aprox 260 OHMs, is ok. The cables are ok.
4) IGBTs power transistors are ok, and the connections wires (CN1) for to control them are ok too.
5) I conected the truck ON, and at the same time I pressed manually the contacts of the PS contactor. Nothing happened. There is not a short circuit on the power circuit, because when I closed the PS contactor´s contacts nothing happend.

please help me!
best regards
