Features

  • Universal Compatibility with Diagnostic Tools: Designed to work with all WABCO PLC trailer brakes, this adapter supports virtually any heavy-duty vehicle communication interface or scan tool, including NEXIQ's USB-Link 2 & 3 and Pocket HD. It ensures seamless integration with your existing diagnostic equipment, making it a versatile choice for ABS brake diagnostics.
  • Comprehensive ABS Diagnostic Functions: Detect and interpret ABS warning lamp messages directly from the trailer ECU, test in-cab trailer ABS warning lamps, and evaluate key SAE J1708 and J1587 MIDs, including MIDs 10, 11, and 136-139. This adapter is engineered to provide accurate, detailed diagnostic information to keep your fleet safe and compliant.
  • Flexible Connection Options for Versatile Use: Whether connecting between the tractor and trailer or directly to the trailer without the tractor, this adapter offers the flexibility needed for various diagnostic scenarios. It simplifies troubleshooting and ensures you can perform diagnostics in any situation, whether in a shop or on the road.
  • Enhanced Communication for Reliable Performance: Supports J2497 Power Line Carrier (PLC) communication, converting power line data to J1708 format. This ensures efficient and reliable diagnostics by enabling advanced communication between your diagnostic tools and the vehicles systems, even in challenging environments.
  • Standalone Diagnostic Capability with Optional Power Supply: For standalone trailer diagnostics without a tractor power source, this adapter requires an external power supply. The NEXIQ 424001 7-way PLC cable is recommended to provide power, making it an ideal solution for independent trailer assessments. Ensure uninterrupted diagnostics, even in remote or off-road settings.
