What triggers it
HFC is activated because all of the following conditions have been met: (1) the master cylinder pressure exceeds a certain pressure; (2) the Anti-lock Braking System (ABS) is not active; (3) the vehicle does not decelerate in time.
When it clears
HFC is no longer active.
Potential impact
Braking performance may be reduced due to faded brakes. The ESP pump may be activated to increase the brake pressure.
