Grip Control
WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 2005 Acura NSX, 2004 Acura NSX, 2003 Acura NSX-T, 2003 Acura NSX, and 2002 Acura NSX-T. However, it is still accessible from the selected car via links, so may be relevant.
Based on signals about wheel speed and lateral acceleration, the TCS control unit determines efficiency of the grip of the tires on the road and signals the throttle actuator to relax engine power if necessary, thus improving grip.
