Details/Specifics on how my rear diff/traction control actually works???
I have been doing lots of searching and reading both here, other forums, google in general as well as the owner's manual and I'm just not coming up with the info I'm looking for
I'm trying to better understand exactly how the rear diff works in my truck
The details of my truck are in my sig
The window sticker just says 3.55 Ratio Regular Axle
It's snowy here and the town where I live likes to sleep in when the roads are covered in snow...
When I turn the traction control off the differential acts just like an open diff, the side with no traction just slips and spins and there is absolutely no technology that is trying to transfer torque to the other side in hopes that there will be traction over there
When I leave the traction control on the diff seems to act like it has some type of limited slip technology, the traction control is not just limiting power it is attempting to transfer torque hoping to find more grip, when this happens I can hear something is going on and I can see the yellow slip light on the dash blink
So, what exactly is the rear diff/traction control doing to try and transfer torque from the wheel that slips to the wheel that grips on the rear axle in 2WH?
The rear diff in the S2000 is mechanical after one side starts to spin the diff locks and acts like a posi track
The Titan had what Nissan calls ABLS as in Active Brake Limited Slip, the ABS system was used backwards to apply brake pressure when one tire would start to slip, thus transferring torque to the opposite side
Any help would be appreciated
Thanks

That's what I'm thinking, I sure wish I knew for a fact, there is so little info out there
When i was trying to figure out exactly what the Wet/Snow Mode does that was a brutal chore and I'm still not 100% sure what I found with google is actually correct
So far this is my biggest issue with Ford, a very poor owner's manual
Thanks for the reply

AdvanceTrac with RSC uses the ABS system to engage brakes individually to control sway and roll, and improve traction.
Throttle reduction is also performed under certain situations.
