The Bendix Trailer Abs Diagnostic Tool (TRDU) is a valuable tool for technicians diagnosing issues with Bendix trailer anti-lock braking systems (ABS). This portable device provides a visual indication of diagnostic trouble codes (DTCs), allowing for quick and efficient troubleshooting. This article will explore the capabilities and benefits of the Bendix TRDU.
Understanding the Bendix TRDU
The Bendix TRDU is designed to communicate directly with Bendix ABS modules on trailers. Utilizing PLC4Trucks communication protocol, it can read and display DTCs related to various ABS components. This allows technicians to pinpoint the source of malfunctions without relying on complex scan tools.
Key Features of the Bendix TRDU
- Visual DTC Indication: The TRDU uses indicator lamps to display specific DTCs, providing a clear and straightforward diagnosis.
- DTC Clearing: Beyond reading codes, the TRDU enables technicians to clear DTCs from the ABS module after repairs are completed.
- Odometer Mileage Readout: The TRDU can display the odometer mileage, providing valuable information for maintenance scheduling and troubleshooting.
- ABS ECU Configuration: The tool allows for self-configuration of the ABS Electronic Control Unit (ECU) on compatible Bendix TABS-6 and MC-30 systems with PLC ECUs. This feature simplifies system setup and customization.
Compatibility and Supported Products
The Bendix TRDU is compatible with a range of Bendix trailer ABS systems, including:
- Bendix® TABS-6™ Standard and Premium Trailer ABS Modules: The TRDU provides comprehensive diagnostic capabilities for these widely used trailer ABS systems.
- Bendix® A-18™ Trailer ABS System with PLC: The tool supports diagnostic functions on trailers equipped with the A-18 system and a PLC.
- Bendix® EC-30™T Electronic Controller with PLC: The TRDU is compatible with this specific electronic controller, ensuring comprehensive diagnostic coverage.
Utilizing the Bendix TRDU
Connecting the TRDU is straightforward. It interfaces directly with the 7-pin trailer connector, eliminating the need for complex wiring or adapters in most cases. Specific Bendix adapters are available for connecting to 6-pin or 9-pin diagnostic connectors if required. These include the TRDU Adapter (Bendix Part Number 802165), the J1587 6-pin Trailer Diagnostic Connector (Bendix Part Number 800790), and the J1939 9-pin Trailer Diagnostic Connector (Bendix Part Number K044767).
Bendix TRDU: A Powerful Diagnostic Solution
The Bendix TRDU is a specialized and efficient bendix trailer abs diagnostic tool that empowers technicians to quickly diagnose and resolve ABS issues on Bendix-equipped trailers. Its user-friendly interface, combined with its ability to read, clear, and configure ABS systems, makes it an essential tool for any technician working with Bendix trailer ABS. While Bendix has incorporated some support for other ABS systems by reading standard diagnostic messages, the TRDU is primarily designed for Bendix ABS and optimal performance is guaranteed with Bendix systems.
