External guided diagnostic tools are increasingly important to the aftermarket business of automotive industry. It occurs mainly due to the extensive using of embedded systems in vehicles, making them more complex and difficult to diagnose. Currently, the techniques used to develop a guided diagnostic tool are strongly dependent on designer’s experience and are usually focused on parts and vehicle’s subsystems, allowing low flexibility and reduced information reusage. This paper proposes a new methodology for development of a guided diagnostic tool applied to the automotive industry. This methodology is based on a three-tier software architecture composed of vehicle’s parts and components, diagnostic information and strategy, and presentation layer. It allows great flexibility for designing a guided diagnostic tool for different vehicle models, parts OEMs and automotive systems. The proposed methodology has been applied to a case study at Volvo Trucks. The corresponding adaptation process to the three-tier software architecture is presented as well as its impact on development costs.
