    I'm feeling completely retarded with this. I've got no codes in the computer with my issue. I think I'm googling this wrong because I can find anyone with the same issue, but....

    When I switch to 4wd hi or lo I get a red flashing on the dash of my 4wd system with an "X" on it Then 4wd Hi starts flashing. If I keep switching the switch in the dash it will stay on until I turn the truck off and back on. Anyone got any clues???? It's a 2008 Tundra with about 210k on it.

    I appreciate the help. Just trying to avoid going to the dealer and not replacing every part until I've rebuilt the whole system if I can.

    When was the last time you turned the 4wd system on? Start with the 4HI. Put truck in neutral - turn the 4hi dial on. Put truck in drive and go slow for 4 or 5 revolutions. I find my truck has a hard time going into 4wd if I don't turn the dial every month or so. This usually fixes itself. Ever since I've made a point to put it in 4wd one a month I haven't had that issues come back. It's like the parts need to be lubed or something. Weird.

    Try switching it into for high and getting under the truck and banging on the actuator with a rubber mallet lightly. I have read that others have done this with success. Sounds like there something wrong with the actuator. Or it’s frozen.

    Check the vacuum lines going to the 4 wheel drive actuator. My 2000 tundra did the same thing and the vacuum line going to the actuator had a split on the end going into the plug
