The development of the TCAN is an initiative of the European Transport Board and supported by Haldex Brake Products, Knorr Bremse and Wabco Vehicle Control Systems. This protocol was officially released in 2014 and will be implemented during the next release of the applicable hardware and/or software.

It’s great to see the 3 major EBS manufacturers agree on an industry standard. With this in place we can read and analyze data independently of the ECU. This makes it possible to compare performance and equipment health between units or even entire fleets.
