Service bulletin SD-20-47682

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® iTABS™ X Standard Single-Channel (SC) Trailer Antilock Braking System (ABS) Module - 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.
