Traction Control Not Working

[Rich718]

   Howdy everyone. New to this forum. I just picked up this 2020 2500HD with a Duramax and the 10 speed transmission. I found out last week in the rain that the traction control doesn’t work. No dash light warning or anything. It’s almost impossible to leave a stop light in the rain without spinning the tires. 
   Before I take a deep dive into it wouldn’t the ABS light be on if there was a problem with the traction control and has anyone else experienced this ? 
    I thought maybe the previous owner might of pulled the fuse or fuses but I read if those fuses are out the ABS light on the dash will come on. 
 

thanks in advance

What kind of tires are on it?

 

If there was a fault, you'd have lights on. I don't know of any way to disable the T/C on those trucks without tossing a bunch of codes.

It’s got BFG All Terrains. I don’t get it either. No code’s or anything.

The spinning of tires doesn't determine if your traction control is not working.  The traction control system controls to a slip target which is faster then vehicle speed.  If you don't have any codes, it maybe more of any issue of your tire performance in wet conditions.

10-4. At one point I was going around 40 with a wet road and punched it. It dropped down and immediately got tire spin and kept spinning what seemed like forever until I backed off. 
Previous pickups were ‘11 2500/Duramax , ‘15 3500 and a ‘18 F250/Powerstroke. Never has this issue with any of them. I have a mid grade scanner that I’m going to plug and see if it shows anything. Maybe I just need to get used to this 10 speed.

Update

 

Still no traction control. No codes or anything. Truck is still nasty to drive in the rain but figured out a work around toad while driving in the rain by putting it in the “off road” setting while still in 2 wheel drive. Way better. So much better I’m done chasing this problem for now.

One thing I do know is, once those BFG's get to around half tread they turn into hockey pucks. Sure the tread pattern is still there for offroad grip but the tire doesn't flex as much anymore. I've never been a fan of them.

10-4 on the hockey puck. Tires have plenty of meat with even a new one on the rear that the dealer put on because of a slow leak. When the tires are spinning I still get no wheel spin light on the dash though. I’ll definitely take look into these tires.
