1. INTRODUCTION
The Bendix ® TABS‑6 ™ Adv MC module is an integrated multi‑
channel (4S/2M) 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:
● A modular design with an integrated Electronic Control Unit
(ECU); pressure sensors; a lateral acceleration sensor; and
Modulator Relay Valves (MRVs) — eliminating external
pigtail harnesses for these components.
● An operating voltage range of 8 - 32 volts.
● An electronic odometer with trip counters & service interval
options.
● A scratch-pad feature with up to 1,008 bytes of freely
definable read/write text space available for customer use.
● An extended data logging feature, including a resettable
drive recorder.
