Summary
Bendix TABS-6 Advanced Trailer Roll Stability Program (TRSP). Single Channel and Muli-Channel application guide.
electronics
BENDIX® TABS-6™ ADVANCED TRAILER ROLL STABILITY PROGRAM (TRSP®)
BOTH SINGLE-CHANNEL AND MULTI-CHANNEL SYSTEMS ARE
AVAILABLE FOR MOST AIR- AND SPRING-RIDE SUSPENSIONS
Lift Axle Control
The Bendix TABS-6 Advanced family of products also features
automatic lift axle control that will monitor the suspension load
of the trailer and automatically determine when the axle should
be lifted or lowered based on the trailer's cargo weight. This
eliminates the need for the driver to manually manage the lift
axle position. Lift axle control will help reduce your operating
costs by reducing brake and tire wear and improving fuel
economy when the axle is not in use. This feature will support
one or two lift axles and is configured with the Bendix ACom PRO
Diagnostic Software tool. For greater convenience, the system
can be set to automatically lower the axle when the trailer is
parked to prevent damage to the suspension during loading and
unloading.
Bendix® TABS-6™ Advanced roll stability system provides trailers
with core antilock braking, along with Trailer Roll Stability
Program (TRSP®), in one efficient package that’s simple to install
and simple to maintain.
Advanced Performance in a Flexible Package
The Bendix TABS-6 Advanced trailer
roll stability system detects
conditions that may lead to a trailer rollover more rapidly than a
driver typically realizes an intervention is necessary. When that
occurs, the system automatically intervenes by applying the
trailer brakes to slow the vehicle and help mitigate a potential
rollover.
Bendix TRSP solutions are self-contained units which operate
with a variety of trailer electrical requirements – from 8 to 32
volts – without a separate power converter. The system can be
purchased on new trailers
direct from the OEM or retrofitted onto
existing trailers.
Designed for Robust Performance, Flexibility, and
Easy Maintenance
Diagnostics are quick via PLC communication with Bendix®
ACom® PRO Diagnostic Software or our Bendix® Trailer
Remote
Diagnostic Unit (TRDU). J1939 CAN-based diagnostics are also
available via ACom PRO on the Bendix® Trailer Information
Module (TIM™).
Simply safer
A trailer roll-stability system is designed to help drivers
maintain control of their vehicles in two ways. First, it
evaluates conditions that may lead to a rollover. Second,
it intervenes by applying the trailer brakes automatically,
allowing the driver to bring the vehicle under control more
effectively.
Choose the Option That’s Right for Your Fleet
Single-channel (SC) Version
Bendix
TABS-6 Advanced is the
first-ever, single-channel trailer
stability system. Our most cost
effective solution, it’s designed to
TABS-6™
be an easier-to-install replacement
Advanced
for the 75% of trailers
built today
with a 2S/1M single-channel
ABS. The unit performs both ABS and trailer stability. It
can mount directly to the air tank on a cross-member
or frame rail. Plus, our single-channel option can easily
accommodate four wheel ends with its four delivery ports.
Multi-channel (MC) Version
With our multi-channel version, most of the key components
– two modulators, the lateral
acceleration sensor, and the
ECU – are efficiently housed in
an environmentally-protected
central modular unit, making
it more simple to install and
easier to maintain. A locking
TABS-6
Advanced MC
connector cover provides a
second line of defense against
water, grime and tampering.
Like the single-channel version, the multi-channel, selfcontained unit provides both ABS and roll stability.

How Bendix
® TABS-6™ Advanced Trailer Stability Systems respond:
A vehicle enters a curve too fast, on high friction pavement, resulting in high
lateral (side) forces acting at the vehicle's center of gravity (CG). Bendix
®
TABS-6™ Advanced roll stability systems apply pressure to the trailer brakes to
reduce vehicle speed and help mitigate the tendency of the vehicle to roll over.
Which Trailer System is right for your fleet?
Singlechannel
Your Trailer Goal
Need the most cost effective / basic trailer stability?
ü
Already have a 2S/1M-equipped trailer ABS system and need to upgrade to trailer
stability?
ü
Multichannel
Already have a 4S/2M- or 2S/2M-equipped trailer ABS system and need to upgrade to trailer stability?
(this situation covers most tankers)
ü
Have tandem axle trailers and have been susceptible to flat-spotting in the past?
(individual wheel sensitivity helps prevent this)
ü
You want to keep ABS functional even when there is one wheel speed sensor faulted?
(possible when multiple wheels are sensed)
ü
You have tridem (three-axle) trailers and want the easiest, fastest solution to trailer
stability?
(three delivery ports per modulator make it easy to plumb)
ü
You have air-ride or spring-ride suspension trailers
?
(both the SC and MC versions are available for either air- or spring-ride suspensions. Requires an external load sensor.)
ü
ü
Retrofit needed? (the Bendix® TABS-6™ Advanced TRSP system can also be ordered on new trailer purchases)
ü
ü
For maximum stability – combine Bendix
® ESP® on the tractor with Bendix® TABS-6™ Advanced
on the trailer
Your fleet can get the maximum amount of stability available by having both systems on the tractor/trailer
combination because these
systems complement each other. Together they cover a wider variety of potential rollover scenarios. This is especially applicable for fleets
that run high value trailers, sensitive loads, or who want the highest safety available.
Bendix safety technologies complement safe driving practices and are not
intended to enable or encourage aggressive driving. No commercial vehicle safety
technology replaces a skilled, alert driver exercising safe driving techniques and
proactive, comprehensive driver training. Responsibility for the safe operation of the
vehicle remains with the driver at all times.
Now you can make trailer roll stability available for almost any trailer.
