BENDIX® TABS-6™ T R A I L E R ABS M O D U L E

TRAILER ANTILOCK BRAKING SYSTEM

Bendix Introduces Our Most Simple, Reliable
and Flexible Trailer ABS Product - Ever

A Simple Choice in Specing Trailer ABS

Bendix makes it possible with TABS-6, a trailer ABS system
designed with numerous configurations, advanced diagnostic
and the fewest connections features. TABS-6 is the smallest
and lightest system with robust features that provide fast and
reliable brake timing for all applications while reducing the
installation and maintenance headaches found with all other
trailer ABS units.

Flexibility In System Configurations

Bendix offers more system configurations than any other
manufacturer, providing greater coverage for your desired
trailer or dolly braking system. With approximately 90 percent
of the North American trailer market utilizing two sensor/one
modulator (2S/1M) installations, TABS-6 is truly optimized for
this standard configuration. However, the system is available
in a variety of configurations up to a 4S/3M design that
accommodate full trailers or trailers with additional lift axles.
Plus, Bendix is the only manufacturer to offer a 2S/2M axle
system.

Simplicity In Design And Installation

The Bendix TABS-6 system eliminates failure points under the
trailer with the fewest electrical connectors of any other
system. The simple design translates to increased reliability
and reduced installation and maintenance costs.

TABS-6 is the only 2S/1M system with an internal modulator
connector providing maximum protection. The integral 5-pin
power connector allows installers to plug the trailer’s chassis
harness directly into the electronic control unit (ECU) which
means that OEMs no longer need to purchase and install a
separate power cable with an additional connection. With the
integrated through-hole bolt design, TABS-6 is very simple
to install with tank or frame mounting without the need for
specialty brackets.

Durability In The ECU

Driving water, salt and road grime wreak havoc under your
trailer, which can compromise the durability of other
manufacturer’s trailer ABS components. Through superior
design, TABS-6 combats these elements with a variety
of features.

The ECU is permanently sealed from the elements. ECU
cavity breathing during temperature changes can lead to
seal failure and contaminant penetration in other systems.
To eliminate this risk, the Bendix® TABS-6 ECU features a
pressure equalization valve. The fibrous membrane valve
allows air to pass in and out of the unit but not water
molecules. Featuring a sliding lock, an ECU connector
cover acts as a secondary protection against water splash,
virtually keeping connector seals dry in all conditions.

All external TABS-6 electrical connectors are positioned
vertically to create a natural and permanent drip loop away
from the ECU. Horizontal connectors found on other trailer
ABS units can cause water to collect and pool within the
ECU, promoting corrosion and early failure.

Advanced Diagnostic Capabilities
Reduce Maintenance Costs

TABS-6 offers an advanced blink code function that
provides technicians with highly comprehensive
diagnostic trouble codes to pinpoint specific reasons for
faults. Other systems feature “dummied down” codes that
may actually increase maintenance costs, as technicians
must spend more time troubleshooting.

Only Bendix offers automatic clearing of ALL trouble
codes for trailer braking systems. This industry-exclusive
TABS-6 feature eliminates the need to move or lift a
trailer following repair work. Alternative systems require
technicians to either jack up the trailer to spin the
wheels or hitch the trailer and drive it around to clear
trouble codes.

To further reduce maintenance costs and trailer downtime,
TABS-6 displays all available trouble codes when
activated, allowing technicians to identify multiple repairs
and order all necessary parts at one time. Some systems
provide only one blink code at a time, requiring that repair
to be completed before viewing the next code. Using
TABS-6 blink code diagnostics, the technician can also
identify stored trouble codes, system configuration and
even trailer odometer mileage – another Bendix exclusive.
