I took it Auto Zone to read the code, but no code ame up. Where is the DLC3 connector that needs to be jumpered to read the code?

With me the ABS lights never come on. After all this time, I still think it's either a sensor, or the ECU has a "glitch". Other than the idiot lights coming on, there is NO issues with VSC or TracOFF in my Sienna. This past winter they both worked flawlessly. When I replace my tires this fall, maybe that will solve this. Maybe not, but it's not a big deal, when I take a long trip, and the lights come on, I stop, restart the Van and they hardly ever come back on untill the next trip. Who knows what it is.

I have a 2002 2WD sequoia that when the outside temperature drops below 32 F, the VSC trac light comes on. This only happens a couple of times a year (I live in Houston). I just disconnect the battery for a few seconds and the light goes off.

HI, I am new in the forum. The VSC computer on my 2005 Sequoia has internal failure, it's the second computer that goes bad, first was the one for the rear window, which we don't even use(it doesn't rain much in the desert)I was not aware of how common these problems seem to be with the Sequoias.
