does the active yaw just reduce the power to the relevant wheel or does it use the brake aswell?

As opposed to other 'traction control' systems (like ESP), the AYC does not interfere with the ECU. It simply splits the torque between the 2 rear wheels.

Sorry, that was an incomplete reply.

It does not interfere with the brakes either, but I believe it uses the reading from the ABS sensors (among others like steering and throttle position, speed, etc)

Thankyou

If you can wait until tommorrow, there will be a full explanation of AYC in the FAQ's...it even has pretty diagrams Rallymans right though it just transfers the torque from one wheel to the other, no brakes involved.
