Remote Diagnostic Units (RDUs) and Trailer Remote Diagnostic Units (TRDUs)

Available until supplies last, these handy diagnostic tools plug directly into diagnostic ports on either the tractor or trailer and offer a focused indicator lamp approach to diagnostics.

Bendix® RDU

The Bendix® RDU offers a visual indication of Antilock Braking System (ABS) component Diagnostic Trouble Code (DTC) information. The RDU can be used on Bendix® Antiliock Braking System (ABS)-equipped semi-tractors, straight trucks, coaches, and buses. Additionally, the RDU provides a method for clearing the ABS component DTCs from Bendix ABS controllers and allows the technician to self-configure the ABS Electronic Control Unit (ECU) on Bendix® EC-17, EC-30, EC-60, and EC-80 ABS controller ECUs.

Bendix® TRDU

The Bendix® TRDU is a diagnostic tool providing the technician with a visual indication of component DTC information from Bendix® ABS for trailers. The TRDU communicates across PLC4Trucks supporting common diagnostic messages. Additionally, the Bendix TRDU provides odometer mileage readout, a method for clearing the ABS component DTCs, and allows the user to self-configure the ABS ECU configuration on Bendix® TABS-6 and MC-30 with PLC ECUs. It will also clear most A‑18 ABS with PLC ECUs (in this case, certain sensor DTCs require the vehicle to be driven).

  • Supported Products:
    Bendix® TABS-6 Standard and Premium Trailer ABS Modules
    Bendix® A-18 Trailer ABS System with PLC
    Bendix® EC-30T Electronic Controller with PLC
  • Hardware Interface Required:
    7-pin Trailer Connector
  • Available Tools:
    TRDU - Bendix Part Number K101597
    TRDU Adapter - Bendix Part Number 802165
    J1587 6-pin Trailer Diagnostic Connector - Bendix Part Number 800790
    J1939 9-pin Trailer Diagnostic Connector - Bendix Part Number K044767

The TRDU unit is specifically designed for use with Bendix ABS, and although Bendix has included some competitive support, based on reading some standard diagnostic messages, Bendix makes no claims for its operation and/or usability with other brands of ABS systems.

Diagnostic Harnesses: Bendix adaptor cables, extension cables, wiring harnesses, and trailer cables allow the technician some flexibility to connect to RDUs, TRDUs, TABS (trailer ABS), and other Bendix diagnostic tools and products. With different sizes, lengths, and configurations available, technicians can usually find the right Bendix harness for the job.
