Centre Diff lock can be activated while staying in High

[brainhax]

Hi,

1997 1FZ-FE , 80 Series, Manual

Upon coming to a challenging section when off-roading, I usually stop, press the diff lock button, Change the Lever to "L" from "H" and set 2nd Gear.
When the tricky part is done, I would normally stop again, press the diff lock button and turn it off, set the Lever to "H" and move.

Questions:

1- When changing to "L" should I must turn ON Centre diff lock? In which cases I don't need to turn it ON when in "L"
2- When in "H" , can the Centre Diff Stay ON all the time? (during off-roading. ). What will it do if it stays ON in "H"

Thank you.

Yes, you can even do it "on the fly". Try not to do it while turning though

In my opinion, a diff lock button and the pin 7 mod is what God intended. You can activate the center diff in high and you can shift into low with the center unlocked. Its all up to the driver.

As long as there is anything but pavement under the tires you can have the center diff locked for as long as you need it. Nothing bad will happen.
I turn mine on when I hit the secondary roads (sand, gravel, clay) and turn it off just before (200m or so) I get back to pavment.
