It controls air brake pressure using input from wheel-speed sensors to prevent wheel lockup during braking, improving stability and stopping distances. This model is configured for a 2-sensor, 1-modulator (2S/1M) layout, which is typical of single-axle trailers and dollies. You would replace it when the trailer ABS warning lamp stays on or fault codes indicate an internal ECU or valve failure.
