I am not sure if I have the atrac or not. The book states you turn it off and on by the button on the steering wheel. I have the button with the truck and swirly lines behind it, but it only works in 2wd.
You should be able to turn off the vsc in 4 hi by pushing the button and holding it down while stopped. I don't know if this turns off trac in this situation, I haven't tried it. If you have A-trac, there will be a button above the front cup holders and below the little cubby hole, and an A-trac light on the instrument panel that comes on in 4 lo when it is engaged. If you have a locker, you can engage both the locker and A-trac, which then will only work the front wheels. The locker engaged turns off ABS.
Hitting vsc button once in 2 wd will engage the ALSD and turn off vsc, until a certain speed, where ALSD will stay on and the vsc will come back on. ALSD will give you more traction by limiting wheel spin with the brakes, without the vsc tinkering with the throttle. Use ALSD when VSC is would prevent you from using full throttle because of wheel spin, like on a muddy road, or coming up the side of a ditch. If you hold the VSC button down for a few second while stopped in 2 wd, it will turn off the ALSD and VSC and it will act like a regular differential with no interference from the computer. Got it?
