It is a 4 wheel traction control,,, Same as the FJ's have ,,, There has been very little info on this system on the 07 Tundra's.... I will try to find more info and post it here,,,,great find but I'm still wondering what A-trac means exactly? I know the auto LSD I took it in high school. man what a trip. but seriously vsc is vehical stability control right? but what is Atrac?

This is very interesting information, however when looking at your later pdf posts it looks as though this may have been an initially planned feature that may have been dropped from the production model (the pdf named chass is entitled 'new model outline'). I wonder if we can get totyota to confirm whether or not this ATRAC feature is actually enabled on our trucks?Here is what is on and off when you are pushing the button,,,, And funny this says A-TRAC, unlike the owners manual,,,,,![]()
I stand corrected, according to the VSCTRAC pdf file posted above ATRAC is enabled in both 4hi and 4lo. And, according to your experiences, this vehicle does indeed have ATRAC. The pdf file also states that there is no ATRAC in 4wd in VSC off mode, which I'm assuming you enter in 4wd the same as 2wd (hold down vsc button for 3 sec while stopped) Good info to know for her virgin dune trip :tu:You can't turn off A-TRAC in the Tundra, there is no switch for this. A-TRAC is automatically engaged when you go into any 4WD mode. I understand the FJ cruiser has an A-TRAC switch but not the Tundra.
When in 4WD other traction control is disabled.
1/3 of my driving is in 4WD and I can confirm that traction control (A-TRAC), is at work.
My slip light has come on many times in 4HI and 4LO, at the same time you can hear the ABS unit regulating pressure to the wheels and feel the tires gain traction.
