This is a ZF WABCO trailer ABS modulator valve that controls air pressure to the brake chambers during anti‑lock braking events. It is commonly used in 2S/1M or 2M/3M Easy‑Stop ABS systems on semi‑trailers. The valve is replaced when it causes ABS fault codes, erratic braking, brake drag, or when the ABS warning lamp stays on and diagnostics point to a modulator failure.
