Diagnostic tool of Sontheim

Development of a diagnostic tool – including a service case with VCI and customer-specific diagnostic cable

In the agricultural sector, manufacturers have a large number of variants and numerous vehicle models for which you have to provide the corresponding diagnostics in the field. Different interfaces to the vehicle, but also different protocols and fieldbuses have to be taken into account and have to be provided to the service workshops accordingly.

To standardize the tools, we developed a modular diagnostic tool for a leading agricultural vehicle manufacturer. This tool is based on standards and enables cross-brand diagnosis of all vehicles. In addition, Sontheim Industrie Elektronik GmbH supplies the appropriate VCI including a wide range of cables to connect to all types of vehicles. All these tools are delivered to the OEM in a robust service case.

ISOBUS, CAN, K-Line and J1939 are just a few of the fieldbuses and protocols that a diagnostic tool hast to interpret in order to access a wide range of vehicle models. In addition, the physical interface is a further obstacle on the way to targeted diagnostics. With the Sontheim service case, which is provided to the OEM, he can equip his workshops with the all-in-one package. This enables a holistic diagnosis of all vehicle variations on the market. The manufacturer thus has only one supplier for all hardware and software, including production and assembly of his system solution. The OEM can rely on the latest diagnostic standards. This enables new vehicle models to be quickly integrated into the diagnostic tool with minimal develop­ment effort.
