In regards to why a truck may still spin only one tire, such as when on ice. There is simply a limit to how much torque can be transferred from the low traction tire (spinning tire) to the one with traction. Part of that limit is in the programming of the system, so basically how much brake force the system applies to the spinning tire. Keep in mind that there is a balance of how much braking to apply to the spinning wheel before you get to the point of diminishing returns....if you apply too much braking you basically lock the tire up in order to get the other tire spinning, but you are now stuck because the one tire is locked up........ There is also the issues of strength of the components since applying to much brake load can put a lot of stress on parts.Doesn't seem like a very good system if the driver has to "understand it" for it to work.
So if all these trucks have this why are they able to spin a wheel when in snow/ice? Like I said, I'm pretty sure this system DOES work on my truck. Haven't had it in snow but in mud the spinning wheel only spun one or two revs before the other wheel started pulling.
One thing to clarify (I'm not specifically replying to this post, but just overall comments that I see)....is that just because one tire is spinning and other tire is not does not mean the system is not working. This goes for BLD/electronic traction control or a limited slip differential. Either system is still transferring torque to the wheel with traction, but it just can't transfer enough torque for it to spin or make the vehicle move forward. For example if you have one tire in the air it basically takes almost zero torque to spin. Even you transfer 100% of the torque to the other tire that is 100% x 0 which equals 0.
