Background
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 lateral stability during braking. All modules include an Electronic Control Unit
(ECU) and Modulator Relay Valve which are integrated into a single self-contained 2S/1M (two sensor, one
modulator) trailer ABS unit.
If the TABS-6 Premium detects additional sensors and modulators during a power-up, the TABS-6 will perform
an upward auto-confi guration. The auto-confi guration allows the module to control additional sensors and
modulators. The TABS-6 Premium P/N 5014016 allows the auto-confi guration as shown in the Chart below.
