Add Control System of the Toyota Hilux 2011

When the double traction lever is operated in H4 or L4 the front differential does not clutter and the double traction indicator light on the board does not turn on. Does anyone have a PDF system diagram that can send me? The number of the system actuator is 41400-35031 and the vehicle is Toyota Hilux 2011. Thank you in advance !!

You should be that the front differential engine does not have water that is the safest, check the engine connector if the cables are not broken,
sometimes those cables stick with each other ahead of the engine carter, these cables go together with those of the alternator.
Remove the glove compartment next to the passenger, behind that is the brain of the double, close the switch, active H4 and then turn on on the switch, inside the brain of the double it must trache as an internal rel, if the brain does well, check the cables, and the engine for that of the water, report me any questions any doubt
