    Hi All, My VSC, Trac, Engine lites came on about a month ago. I tried the new gas cap and reset, stayed the same. Last week, the annunciator started beeping from the moment I started it until I shut it off. I bit the bullet and brought it to Toyota. They called last nite, and said $2200.00. It needed a 4 wheel ECU. My question is, are these available used? If I disable the beeper, will I hurt anything by driving this way? I realize it will not go into 4 Low, but just checking that driving this way will not do MORE damage, until I can scrape up the money.
    Thanks in Advance for help with this! 03, V8.

    You should be able to get one from a yard or maybe eBay. Not sure since it’s 4wd all the time.

    Will it hurt anything to run it, as is, until I can get a used unit? Is this plug n pray, or does it need programming? Appreciate the help!

    I’m not sure on damage if you run it as is. The new ecu will be plug and play.

    Thanks for the help. The service dept said what I needed was 4 wheel drive ecu, I'm a little confused if that is an ecm or computer. I'm very baffled on why a dealership would mark up the price of either of those parts, $280 or $900 and tell me almost $1900 for part Plus install. Great group!

    Hi All, I'm on phone with dealership, trying to figure correct part. They are insisting now is the ECM, but they disconnected it to stop the beeping for me, and its running fine. Would car run if ECM is disconnected, or did they perhaps disconnect the 4 wheel dive computer?

    Update: Finally got dealership to admit they were trying to charge me to replace the ECM, when indeed, I really needed the 4 wheel drive computer. Pretty sad for dealership service to do this to me. Because if I had them replace ECM, they then would have come back and said I need the computer, too! Thanks for everyone's help on saving $1900.

    Yea you gotta watch them they’ll try it again most likely. I travel 2 hours to a dealership if I need anything because all the local ones can’t be trusted.

    Good, glad you got it figured out. Our Lexus and Toyota service Dept. Is in the same building and I’m sure the techs are the same but I’ve had the Toyota service treat me very differently than the Lexus. Lexus wanted to put new tires and brakes on the rear of her IS300 and I called and told Toyota what I wanted to do and their quote for the same work was half. I don’t go to either anymore...

    Thanks for info, sadly, I found the same part, at another Toyota Dealership for $140 cheaper, than the one I went to. Toyota should atleast have price matching, between dealerships!!!!!!! :)

    Please update when you do this and maybe take a short video. I'm still not exactly sure how this happened and how to fix it. But it will be good information for all of us to know in the future.

    Glad the group was able to steer you in the right direction.
