The abbreviation PSI5 stands for Peripheral Interface 5. PSI5 is a common interface that connects external sensors in the car with the ECU.


Since the early beginning, IHR has been part of the PSI5 working group. Therefore, we are the co-editor of the test specification V1.3. Under the leadership of IHR, the test specification V2.0 has been defined recently.


In the meantime, IHR possesses a profound knowledge in testing ECU`s and sensors with the PSI5 interface, as well as offering professional training in the PSI5 environment. We perform tests according to all common specifications, from V1.3 to V2.x.
