Wow, this is an old thread...come back to life! lol. Titan has VDC (Vehicle Dynamic Control), and ABLS (of course not all models have these features). That's it. there is no "traction control" per se. VDC keeps you from veering off your intended path while ABLS uses the ABS sensors to brake the slipping wheel. Trucks with VDC have a button to turn it off...partially. Because VDC can also kill engine power to do it's job, that portion of the VDC cannot be turned off...which is why you'll hear some complaining that even with the VDC off, engine power is interupted while spinning a wheel. ABLS does not kill engine power, it just uses the ABS to grab the slipping wheel...which may be why some claim it doesn't work well at anything above slight throttle inputs. This is how it was explained to me by my dealers regional guy back when I spoke to him in 08 when I was buying my new truck.
