Brake control:

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

In addition to reducing the engine power (driving-stability control), the TC (via the ABD) brakes the drive wheel that is spinning. Since this control requires the drive wheels to be individually controlled, the ABS/TC system is a 4-channel system.
