How to Activate the Tag Axle Option with TOOLBOX Software

Once the Tag Axle hardware has been installed, the Generic I/O Tag Axle option must be activated using WABCO TOOLBOX Software version 12.2 or later.

After Generic I/O activation, the End-of-Line test must be completed for new builds or new ECU
replacement. Refer to the procedures in this manual or Installation Guide TP0887, Trailer ABS with Roll Stability Support (RSSplus™) for Trailers with Air or Mechanical Suspensions, for step-by-step instructions on programming and conducting the End-of-Line test.
