    In this research note, we take a look at the field of mobile work machine diagnostics. The perspective by the authors is limited by the research project (KODIE) behind this research. However, we have tried to provide generic guidelines for machine builders to set up their diagnostics strategy. Building blocks, like SAE J1939/73, ISO 15765 and ODX, from automotive industry are exhibited to prevent machine manufactures from reinventing diagnostics protocols and practices. Furthermore, examples of diagnostics architectures are presented, with OSA-CBM among others. To make the most of diagnostics data, an extensive set of data analysis methods are introduced. And in order to help engineers to design diagnostics feature for the sensor system, hints and examples are supplied as to how to establish the fault modes of sensors; a good knowledge about the (relevant) sensor and actuator fault modes is a prerequisite for comprehensive fault detection.
