## NHTSA's summary

Service Data \- Bendix® TABS‑8™ Advanced Single\-Channel Trailer Antilock Braking System \(ABS\) Module The Bendix® TABS‑8™ Advanced Module is an integrated single\-channel \(2S/1M\) trailer service brake module controller for air\-braked, heavy\-duty semi\-trailers that features the Bendix® Antilock Braking System \(ABS\) and the Bendix® Trailer Roll Stability Program \(TRSP®\). Installed on semi\-trailers, the TABS\-8 Advanced 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 TRSP monitors the trailer’s motion and reduces the risk of rollovers by automatically applying the brakes when a risk of rollover is detected.
