OBD software offloads ECU developers
Vector offers an add-on solution for the AUTOSAR modules DCM, DEM and FIM for the growing numbers of ECUs with Comprehensive Component Monitor functionality. Not only do the modules consider the extensive OBD standards and directives, they are also adapted to the special needs of the supported OEMs. Comprehensive Component Monitor functions are found in such ECUs as those for battery regeneration while braking the vehicle and in the areas of battery management and climate control.

The named modules are bundled in the MICROSAR DIAG product and are available for both AUTOSAR 4 and AUTOSAR 3. Just like certain other AUTOSAR modules, these three modules can also be used in projects that are not based on AUTOSAR, e.g. CANbedded projects.
The monitor functionality in OBD-relevant ECUs is subdivided into what is known as “Major Monitors” and “Comprehensive Component Monitors”. Major Monitors are supervising systems that have a direct effect on emission values, e.g. in fuel and exhaust gas recirculation systems. Comprehensive Component Monitors check the systems that are needed for the Major Monitors and only have an indirect effect on emissions.
