At Alliance Transport Technologies we have worked with our customers to identify the common faults on this ECAS unit and discussed how we can repair them.  The most common faults that we see relate to communication issues and accelerator faults.


When we receive an ECAS Unit to repair, we will talk to you about the faults that you have seen and then use our diagnostic equipment to test thoroughly for that fault as well a more thorough inspection of the unit.  We will then fix the faults we have found using components that satisfy our stringent quality criteria – and we believe we apply a higher quality standard than the manufacturer.



ECAS (Electronic Controlled Air Suspension) is a system that’s able to adapt to the various load conditions of a trailer. It is an electronic component that communicates via the ECU to adjust the trailer riding height for loading and unloading which creates less wear and tear on the trailer.
