Service Data - Bendix TABS6 Advanced Single-Channel Trailer ABS Module The Bendix TABS6 Advanced module is an integrated single-channel (2S/1M) trailer service brake module controller for air-braked heavy-duty semi-trailers that features Bendix Antilock Brake System (ABS) and Bendix Trailer Roll Stability Program (TRSP). Installed on semi-trailers, the module acts as a relay valve during normal braking, but during ABS events it will intervene to help maintain vehicle stability and minimize stopping distance by preventing wheel lock-up. The Bendix TRSP monitors the trailers motion and reduces the risk of roll overs by automatically applying the brakes when a risk of roll over is detected.
