05 Grand Prix GXP P0856 code

My GXP is throwing this code. It lights up the ABS light, the traction control and the other light that I can't think of right now.

According to the reader, it has a p0856 code coming up. I know that it is defined as the Trac Control Torque Request Circuit but I don't know what that means or where to look for the fault.

Can anyone point me in the right direction?

I'd check the wheels hubs, or specifically, the wires/connectors at the wheel hubs. Make sure the connections are good and that the wires are not frayed or damaged.
