Luv Dmax 3.5v6 does not connect 4L

My greetings to all the members of the forum, I tell you that I have a DMAX V6 2008 to which Ruleman's thrust and clutch disc change, to make it faster what I did was to give off the engine and run it forward and the box behind and thus I got the space to disassemble. Arme everything is well, the 4H connects perfect but now it does not connect the 4L. The light is itermant and then goes out and nothing. If someone can help me with this issue, I would be very grateful, greetings!

Hello everyone, Leandro , to be able to guide him in the diagnosis procedure and very important that he tells us if those flashes of the light or witness are 2 or 4 Hz, that is 2 or 4 flickers per second, before going out and not doing anything. Assuming that the engine is slowed down (low 2000 for 6VE1), neutral gear lever, pizzy clutch and stopped vehicle, these are the 4 basic conditions for the LOW of the Tranfer to gender. greetings!!!
