TABS-6 Trailer ABS Module

FIGURE 1 - TABS-6 STANDARD AND PREMIUM 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 TABS-6 module is

auto-conﬁ gurable to control more sensors and modulators (up to

4S/3M) from its default 2S/1M.

Bendix

TABS-6 modules also feature:

• Internal electrical connections to the primary MRV,

eliminating the need for external pigtail harnesses.

• Optional mounting to the service reservoir or to the chassis,

without additional brackets.

• Blink code diagnostics and support for advanced diagnostic

tools.

• Support for Power Line Carrier (PLC) communication to the

towing vehicle.

• A pressure equalizing valve in the sealed ECU housing to

give improved protection from water, etc.

• A locking dust cover to provide additional electrical connector

and cable protection.

• A serviceable nylon ﬁ lter to help prevent foreign material

from entering the control port.
