Circuit Option
The anti-lock system is controlled by the electronic
brake control module (EBCM) whenever the vehicle is
in motion (under power) over 5 mph. The EBCM
constantly monitors the speed at each wheel (rear
wheels act as one), and is activated when the brake
pedal is pressed. The EBCM, in turn, alternately brakes
the wheels individually, allowing better control during
braking on slippery surfaces.
