For a sensor supplier to the automotive industry BRACE provided consultancy with regards to OBD. The sensor supplier was getting an increasing amount of questions from their customers on the OBD "readiness" of their sensor. In addition the general trend was that the sensor itself got more intelligent which also required that some diagnostics had to be build-in into the sensor.
BRACE setup a failure mode analysis of the sensor and its associated ASIC using methodologies from the Functional Safety and System Engineering domain. From there we identified where diagnostics were needed. BRACE advised which diagnostic had to be executed within the diagnostic and which diagnostic would have to be implemented by their customers to complete the OBD coverage.
