Functional EB+ valves are always a combination of “Electronic Control Unit” and “Pneumatic Control Unit”. GEN1 of our EB+ series has a service friendly interface between both units. In case of a faulty system it is possible to change either the ECU or the valve. This is very cost effective for the end user. Because of higher function integration and for cost reasons at OEM our second Generation does not offer this feature anymore. Nevertheless all cables for GEN1/2 (excluding DIAG port) are still fully compatible to latest GEN3. Recent new auxiliaries features are often also available for previous generation (by Flash Update). This future orientated design secures today’s investments in the future.
