"RR DIFF LOCK" problem please help

Hello guys.

I really need some help.

After I pulled my Differential Actuator out and check the motor applying power directly to the #2 and #3 plug, found out that is working properly. Now my problem sounds like a electric problem.

With the actuator out but plugged, I press the RR DIFF LOCK switch and the gear wont move.

I never had any problem or indication light coming ON. All it did was that the RR DIFF LOCK stop working but it did work before about (1 year ago)

I read most of the threads related to the RR DIFF LOCK issues but it looks like most of the time is the actuator the problem, but not in my case.

Any suggestion?
Any relay that I should replace?
I can't find a relay and/or a fuse dedicated to the "RR DIFF LOCK"

That's mean that the COMPUTER is bad?
Why no CHECK ENGINE LIGHT?

Any advice will be appreciate.


Thanks

 

Bump...

 

This is from the locker mod, but you can see the pin outs of where to check for power. Also here is a link to the factory manual on how to check it- http://www.customtacos.com/tech/files/05FSM/data/ileaf/06toyrm/06toypdf/06rmsrc/rm2006ta/037008.pdf

 

After few days and hours of troubleshooting and over 10hours of search on the internet and on this forum...



I had the computer out and was trouble shooting step by step, whit the diagram, then when it was time to check the fuse, searching the location of that fuse, got across the above post from 2011.

The fuse on the Fuse BOX that say 4x4 it was for the DIFF LOCK mode, even that my truck is 2wd it has that fuse in the fuse box and I removed that fuse to used it on something else about a year ago.

I feel like an idiot.
