This part of ISO 22900 provides the framework to allow diagnostic and reprogramming software applicationsfrom all vehicle manufacturers the flexibility to work with multiple vehicle communication interfaces (VCI) frommultiple tool suppliers. This system enables each vehicle manufacturer to support all vehicle communicationinterfaces to perform diagnostics and to control the programming sequence for electronic control units (ECUs)in their vehicles.This part of ISO 22900 describes the applicable use cases to justify the benefits of ISO 22900. It alsospecifies the design requirements to be followed by diagnostic and programming vehicle communicationinterface designers. The design requirements are categorized into different levels of conformance classes toprovide:-- "software compliance", a set of requirements for existing VCIs, which are software but not hardware compliant;-- "electrical compliance", defining all signals and electrical interfaces that allow a system integrator to connect more than one VCI Protocol Module to the vehicle diagnostic connector and the host system; "mechanical compliance", defining standard connectors on the VCI Protocol Module to interface to the vehicle Data Link Connector (DLC) and the host system, as well as defining a cabling concept to support interfacing more than one VCI Protocol Module.The technical requirements specified in this part of ISO 22900 have been influenced by the requirements oflegal authority with regard to "vehicle OBD and programming".The Modular Vehicle Communication Interface hardware design requirements will provide appropriatedevelopment guidance for vehicle communication interface manufacturers to meet legal authority andautomotive manufacturer demands with regard to inter-vendor operability.
