TABS-6 ADVANCED TRAILER MODULE INSTALLATION GUIDELINES
®
™
It is the responsibility of the trailer manufacturer to inspect all trailer Antilock Braking System (ABS) components
prior to installation on the vehicle for any external damage, such as cracked valve ports, electronic housings, etc.
Any components found to be damaged shall not be installed on the vehicle and must be replaced.
The TABS-6 Advanced Module is designed to meet FMVSS 121 timing requirements when installed per Bendix![]()
recommended installation guidelines and/or Bendix
system drawings:
• FMVSS 121 timing compliance is the responsibility of the towed vehicle manufacturer.
• As a minimum, 5/8-in. tube size should be considered for the supply port, when frame-mounting the TABS-6 Advanced
Module.
The TABS-6 Advanced Module shall be mounted with the followings considerations:
• Within ± 40 in. of the center of the axle(s) for proper balanced brake applications.
• With exhaust port facing downward and unobstructed with significant free space below (> 1 in.).
• Within ± 2 in. from the centerline of the trailer (default):
◦W
ith the Bendix
® ACom® PRO™ Diagnostic Software, a left/right offset greater than ± 2 in. can be programmed in
the Electronic Control Unit (ECU).
• Yaw angle shall be ± 10° as measured from the centerline of the trailer.
• Pitch angle shall be ± 10° as measured from a flat horizontal plane.
• Roll angle shall be within ± 5° as measured from a flat horizontal plane.

Failure to properly install the TABS-6 Advanced Trailer Module and other components can result in
impaired ABS and TRSP system functions, which can result in a collision or rollover, causing property
damage, serious injuries, or death. Be sure to read, understand, and follow all recommendations and
guidelines carefully.

TABS-6 ADVANCED TRAILER ECBS MODULE INSTALLATION GUIDELINES
®
™
For consideration during installation of the TABS-6 Advanced Module, the Wheel Speed Sensors (WSS) follow the
orientation of the module as shown below:
• It is necessary to fix the WSS to the orientation of the internal lateral acceleration in the Electronic Control Unit
(ECU) for plausibility checks between the sensors.
• If the WSS location does not match the orientation of the module, a fault will be generated and the Antilock Braking
System (ABS) indicator lamp will be illuminated.
