Advanced Single‑Channel Trailer ABS Module
1. INTRODUCTION
The Bendix
®
TABS‑6
™
Adv module is an integrated single‑
channel (2S/1M) trailer service brake module controller for
air‑braked heavy‑duty semi‑trailers that features Bendix
®
Antilock Brake System (ABS) and Bendix
®
Trailer Roll Stability
Program (TRSP
®
).
Installed on semi‑trailers, the 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 Bendix TRSP
monitors the trailer’s motion and reduces the risk of roll overs
by automatically applying the brakes when a risk of roll over
is detected.
This module features:
