Text of the manufacturer communication

Service Data - Bendix® TABS-6™ Standard and Premium Trailer ABS Modules INTRODUCTION The Bendix® TABS-6™ module is an integrated trailer ABS controller and modulator for air-braked heavy-duty trailers, semi-trailers and dollies. The module acts as a relay valve during normal braking, but during ABS events, it will intervene to help improve stability. All modules include an Electronic Control Unit (ECU) and Modulator Relay Valve (MRV) which are integrated into a single self-contained 2S/1M (two-sensor, one modulator) trailer ABS unit. The Premium Bendix TABS‑6 module is auto-configurable to control more sensors and modulators (up to 4S/3M) from its default 2S/1M.
