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.

 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.
