It monitors wheel speed sensors and selectively modulates air brake pressure to prevent wheel lockup during braking, improving stability and stopping distance. You would replace this module if your trailer's ABS warning light stays on, diagnostic trouble codes indicate ECU failure, or the unit is physically damaged. It is intended for standard trailers built after March 1, 2001 and must not be used on trailers with turntables, steerable axles, or converter dollies.
