Service bulletin SD-13-47672A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Service Data - Bendix® TABS‑6™ Advanced Multi-Channel (MC) (ABS/TRSP) and MC LITE (ABS Only) Trailer Antilock Braking System (ABS) Modules INTRODUCTION The Bendix® TABS‑6™ Advanced (ADV) Multi-Channel (MC) module (Generation 2) is an integrated, MC (4S/2M) trailer service brake module controller for air-braked, heavy-duty semi trailers that features the Bendix® Antilock Brake System (ABS) and Bendix® Trailer Roll Stability Program (TRSP®). TABS-6 ADV MC offers a LITE version, which provides an ABS-only functionality while keeping the benefits of having a multi-channel system. NOTE: All references to the TABS-6 module in this document – aside from TRSP-related references – also include the MC LITE module. Installed on semi-trailers, the module acts as a relay valve during service braking, but during ABS events, it may intervene to help maintain vehicle stability by modulating brake pressure at the wheel ends. The Bendix TRSP monitors the trailer's motion and reduces the risk of rollovers by automatically applying the brakes when a risk of a rollover is detected. NOTE: The Bendix TRSP is not available for TABS-6 MC LITE.
