    alright i dont know what to do here if anyone does please let me know. i got into my truck earlier and the 4lo light with the green 4 wheel drive indicator are flashing. my truck is not engaged into 4 wheel drive either? i have not had it engaged in probally a week. i have tried unhooking the battery to reset the computer and that didnt work. i have tired engaging the 4wd and it does even engage. i honestly have no idea here i guess i will be calling the dealership in the morning unless i get it fixed somehow. and do you think my lift could have affected this i dont see how it could since it is the 4wd and is not engaged and has not been in a week or so. im guessing it is a computer malfuntion but please HELP!!!

    thats what im thinking but do you think that a computer malfuntion would keep it from engaging and disengaging?

    stop truck with foot on brake put in neutral... then switch to 4hi then to 4lo...

    in reverse stop with foot on brake put in neutral... switch to 4hi then to 2hi...

    if this dont work let the truck sit and cool down... after some time try again. if still nothing take in on a slow drive down to town... drive into the toyota dealership and tell them your shit is broke and they need to fix it.

    hope this helps.

    just to let everyone know if you ever have this problem i got it looked at. the dealership found the problem. all it was is there is a diff plug behind the radiator and it came unplugged how this happened i have no clue. but it is hard to see unless you know it is there. just thought i would help someone if it happened to them.

    Hey there WhiteTaco,
    My 06 started having the identical symptom in 05/2010. Until now I thought I was the only person on the planet who had it. Difference is that it's very intermittent and not constant like yours was. I've gone 2-3 months w/o it occurring. The dealer has not been able to diagnose it yet. I've driven it into the shop with the symptom occurring (4LO and chassis lite flashing and drive selector unresponsive). Usually turning the eng off and back on clears it up, sometimes not. I do not have a lift on mine but I'm wondering if this "diff plug" (if it even applies to me) is the culprit. Maybe it's half-in/out and jostles around? I live in Frederick MD a few hours from you. I would like to have the ServMgr at mine and your dealership talk. Could I possibly get the contact from you? Dealership, location, phone#, ServMgr name? This has me pretty stressed. I'm getting to where I can't trust going out in snow/ice thinking it might fail. Please let me know.
    Thanks,
    -Skip

    If anyone else has any ideas on this please reply. Thanks.
    54k miles - drive train warranty only.

    Anyone have a picture of this plug? I am having the same issue, but my truck is 700km out of warranty, so before I drive it 150km to a dealership to find they wont cover it, I would like to check the plug.
    Thanks.

    After 17 months of going back + forth with the dealer and trying to reproduce my intermittent problem, I finally got this fixed. I reported the problem at 54k miles (within drive train warranty so it was still honored after 60k) and at fix time it was 64k miles. They ended up replacing both actuators which involved dropping the transmission. They said "the rods inside the actuators were sticking". Their part + labor cost was 3700. I hope your issue is the plug. Good luck.
