    Ok.... brand new to the Taco thing. Just bought a used Taco last weekend. I’ve wanted one for a LONG time, and I LOVE IT :D. 2011, 19k miles, Double Cab, Silver Streak Mica, TRD Offroad, $23k. Still covered under the Manufacture's warranty.

    The problem is this, when I press the Rear Differential lock button, the light flashes, but never stops flashing. I’m under the impression that it is supposed to flash until it locks, then turn solid once it is locked. Am I missing something? Im at a complete stop, press the button, and sit there watching a flashing light. Is this something I need to take to the dealer or am I just doing it wrong?

    Any help you can give to this nubie would be greatly appreciated.

    :help:

    I sometimes have to let the truck roll forward, and sometimes backward for everything to get lined up and it to engage. Taking it out is the same way.

    Are you in 4Lo? If you don't have the locker anytime mod done you might have to be in 4Lo for it to engage

    Ah, yes, it says prerunner right over there. I'm on a roll today. Just try moving the truck back on forth, it should go in.

    Herp derp haha. We all missed that one. Try turning in sharp radius turns forward and backward to get it to lock in. If none of that works have someone get by the third and hit the button. If you hear it making noise it might be operator error or a slight issue, if the actuator not making noise, there is a big issue

    What I do is this:

    Come to a complete stop, hit the Locker button, slowly roll forward while turning the steering wheel left and right a bit until you hear a lock snap/knock/clack from the rear of the truck. That's your locker engaging. You need to create a little different wheel spin on your back tires so the locker can engage.

    Yep. On dirt. Don't turn or have a locker on while you are on asphalt. As soon as you drive on dirt, just come to a stop, hit the button, drive forward and turn the wheel back and forth, you'll hear a loud 'clack!' From the rear end, and your lights should be good :)

    Nothing wrong bro. Trust me, the way you described sounds like exactly what happened to me the first few times I went offroad, before I figured out how to do it. Also, locker might not have been used much before, so it still takes a little to kick in. Mine seems like it pops right in with no issue now. The first few months of using it, it took a good couple of yards of wiggling around before I heard it click.

    Do yourself a favor, roll your window down and you can hear the 'clack!' Pretty clearly, then your locker light should go solid. And you're good to go! Do it again when you want to turn it back off

    Tried your recommendations this morning and they did the trick. She handled the trail like a champ. I was able to go places I never would have dared in the old Dodge. Not too shabby for a 2wheel drive. Thanks for all of your help!!!

    Tried all the suggested steps in and out of 4WD with my Tacoma, still no dice. Is my actuator bad, or could it be something simpler?
