Antilock Braking Mode Description: Hold
WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.
When the EBCM (Electronic Brake Control Module) senses the wheel slip, the EBCM closes the NO valve and keeps the NC valve closed in the brake pressure modulator valve in order to isolate the system. This holds the pressure steady on the brake so that the hydraulic pressure does not increase or decrease.
