Rear differential won't lock?

    I'm not offroading today, but I was poking around trying to figure out what some of these buttons are for. I've only once ever tried to use the rear diff locker and my truck was top-of-the-tires deep in the mud at the bottom of a lake at the time (all's well that ends well, so don't ask :D). So it didn't seem surprising that all sorts of things wouldn't turn on, including the rear diff locker. Now here I am in a dry parking lot with the manual open and trying to figure out some of these buttons line A-Trac, VSC Off, and Rear Diff Lock.

    As far as I can tell I've followed the instructions to lock the rear diff in the manual pretty well and it says the rear diff lock light should blink for a few seconds while the computer engages the locker and then the light should stay on. The light just keeps blinking though. I've tried it in P, N, and L by itself, and in N with L4 engaged.

    Also sometimes (but not every time) when I put it in L4 the 4Lo light doesn't come on, but as soon as I shift it out of N the light blinks and a chime sounds.

    Any ideas?

    Easy forward then go back to neutral for the 4Lo. For the locker you wana crawl in 4Lo while turning left and right. But I would advise NOT doing it in a paved parking lot. If you have access to a dirt road or vacant dirt lot, try it there.

    yea the "E" stuff like locker and 4Lo are sensitive....the blinking (not engaged) just helps not break it. Took me a while of practice to get em to work.

    This.. & I'll add that too many here that have E locker/4wd don't energize their systems until they're ass deep in mud or stuck on an impossible hill,etc; & when they need it, they can't get it.

    with eletrically controlled lockers /4x ya gotta "use it or lose it" meaning you dont have to offroad it, just initialize & energize a couple times a year that way when you really do need it , it'll be there for you...

    Like the others have said, you need to engage the rear diff lock often to get it to work correctly. Even on dirt roads, you may have to make very gentle turns to get the locker to engage. The more you engage it, the faster it will engage.

    Ive been telling my sister that same thing for months, but she wouldn't believe me. Finally I took the manual out of her Sequoya and read her the part that said "4wd should be engaged for 10 miles per month" or some crap like that. Now she wants to hit the trails

    And now for my next stupid question...

    If the locker comes on best when you're crawling forward, and you're stuck... how is the locker supposed to turn on? Or is this just to get it to turn on occasionally so it will turn on if you're stuck and can't move?


    Right. Can you tell this is the only 4x4/OR vehicle I've ever owned? Thanks for answering my questions and for not telling me the problem can be easily found between the steering wheel and the driver's seat. :D

    That would involve looking at where you are going. Where's the fun in that?

    The owner's manual sorta has this scenario set up where you've found yourself in a ditch, and now you need to get out of it. So you first try L4, and if that doesn't work, you turn on the rear diff lock. So that's why I wasn't so sure. Toyota makes it sound like once you're stuck, you turn this stuff on.

    Despite the assertions of a friend (under the influence of Mr. Pete Coors) to the contrary, you can get a Tacoma into something it can't get out of. Like top-of-the-tires deep in a muddy lake bottom.

    4wd and locker needs to be lubricated from time to time. So when you need it when you are stuck it will work. Make sure you switch things on and off monthly and it will engage in stand still
