Text of the manufacturer communication

Service Data - Bendix® iTABS™ X Standard Single-Channel (SC) Trailer Antilock Braking System (ABS) Module INTRODUCTION The Bendix® iTABS™ X Standard Single-Channel (SC) Module (hereafter referred to as the iTABS 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). Installed on semi-trailers, the iTABS 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.
