Park the vehicle on a level surface, apply the parkingīrakes, and always block the wheels. SAFE MAINTENANCE PRACTICESWARNING! PLEASE READ AND FOLLOW THESE INSTRUCTIONS TO AVOID PERSONAL INJURY OR DEATH:When working on or around a vehicle, the following general precautions should be observed at all times:1. Depending on the load on the power line, the amplitude of the PLC signal can range from 5.0 mV p-p to 7.0 V p-p. The PLC signal is an amplitude and frequency modulated signal. For more information on these diagnostic tools, contact Bendix or refer to your local authorized Bendix dealer or distributor.Īn oscilloscope can also be used to verify the presence and strength of a PLC signal on the power line. At power-up or during a trailer ABS fault condition, the TABS-6 module will signal the tractor ABS unit to illuminate the dash-mounted trailer ABS indicator lamp.ĭiagnostic tools are available that detect the presence of a PLC signal and perform further system diagnostics directly on the power line. Identifying and Measuring the PLC SignalA TABS-6 module will continuously broadcast PLC messages that indicate trailer ABS status. TABS-6 modules support PLC communications in accord-ance with SAE J2497. The signal, using a heavy vehicle industry standard known as PLC4Trucks, is typically broadcast by the trailer ABS ECU over the blue wire (power line) of the J560 connector. POWER LINE CARRIER (PLC) COMMUNICATIONS Since March 1, 2001, all new towed vehicles transmit a signal over the power line to an in-cab trailer ABS Indicator Lamp. It is recommended to use two Grade 5 3/8-16 bolts, typical length 5", torqued to 180-220 in-lbs. A tank with a reinforced port must be used.įrame (Chassis) Mount The TABS-6 module provides through-holes for frame mounting directly to the trailer frame rail or cross-member. Tank (Nipple) MountThe TABS-6 modules can be tank-mounted using a schedule 80 (heavy gauge steel) 3/4" NPT nipple directly between the trailer supply tank and the module's supply port. See page 5.īendix BR9235 Pressure Modulator Valves (0, 1, or 2 depending on confi guration). Each sensor is installed with a Bendix Sensor Clamping Sleeve. Through-holes for Frame(Chassis) MountingĬOMPONENTSInstallations of the TABS-6 Module typically utilize the following components: Bendix WS-24 wheel speed sensors (2 or 4,ĭepending on confi guration). 15 Service Replacement of Other ABS Controllers. 13 Contacting Bendix.14 Servicing the TABS-6 Module.15 Removing the TABS-6 Module.

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 module acts as a relay valve during normal braking, but during ABS events, it will intervene to help improve stability. INTRODUCTIONThe Bendix TABS-6 module is an integrated trailer ABS controller and modulator for air-braked heavy-duty trailers, semi-trailers and dollies. FIGURE 1 - TABS-6 STANDARD AND PREMIUM MODULES
