Traction control, does my '07 have it and if so how is it supposed to work?

So here's what's going on. My rear tires break loose or even spin when just taking off on medium acceleration if the roads are even just a little wet. I notice also that the rear tires will the same when going over painted crosswalks. I was under the impression these trucks have traction control and that it should keep the rear tires from breaking loose. This is going to be a really problem since it's starting to rain more and more her in the Northwest. The only way it seems I can prevent this is to drive like like a slug. It doesn't seem possible to start out in 2nd either.
Am I misunderstanding what traction control is really supposed to do or does mine not work?
My wife's Acura SUV has it and I've never broken the tires loose. That car is AWD so maybe that plays a part in it?

 

@bleach I also have an 07 DC SR5 in PNW. The traction control will use the ABS system to keep a tire from slipping. It's loud and you don't want it running every time you accelerate. In my opinion it is too sensitive. Last Saturday I took a wide arcing turn at a large angled intersection at 45 MPH, in the rain. The traction control activated to stop the truck from a hardly noticeable slip. It made the ridiculous abs grinding noise from applying the brake to one or more of the wheels to control the slip... presumably, because it doesn't think I know how to drive. Then my 8 year old asked me why the car made that loud noise.

Any full time AWD isn't going to slip on wet pavement unless you want it to or have terrible tires.

You will just have to start like a slug or try different tires. You can also do a zero point calibration to make sure the system is set correctly. You should be able to find and abandoned wet road and get the system to activate, pretty easy just trying to fishtale a little. That said, on our 4runner we switched from some newish coopers to bridgestone (new take offs from a taco) and it helped with wet traction quite a bit.

 

My tires that came with the truck have plenty of tread but they're not the brand I would normally buy. I'll try the calibration on my way home this afternoon and see what happens. I have a feeling that it's also due to its low 1st gear and 4.10 axle ratio that plays a part in it. I wish there was a way I could just start out in 2nd.

 

That too - You’ll have to take a load of gravel everywhere, or maybe a rack loaded with off road gear to weigh it down.

 

Following up here. So the only way I found I can prevent my tires from breaking loose while accelerating on wet pavement at a stop light is to shift it to 4HI. Problem solved.

 

Crappy tires will absolutely do this. Plenty of people around here buy new Tundras and toss the stock rims/tires for something fancier, so finding a pair of Michelin tires with 100 miles or less on them for a few hundred bucks is a real possibility.

 

Yeah I just saw a set with factory alloy wheels like mine for $400 locally. ~70% tread by what the seller says.
I think I'll wait until I need new tires and get some BFG AT's.
