Network SimulationEngineersSimulate a virtual J1979 network to test how electronic control units (ECUS) interact with each other under various conditions, validating the functionality of control. 
Compliance TestingManufacturingEnsure that products comply with J1979 standards by providing a standardized way to configure and test communication between devices on the network. 
Software DevelopmentEngineers & DevelopersEnsure software modules communicate correctly over a J1979 network; map software variables to specific messages and signals on the network for proper data exchange between ECUs. systems before physical implementation. 
Custom Dashboard ConfigurationsDevelopersCreate custom dashboards and visualization tools and map specific signals from the J1979 network to graphical elements on a dashboard, providing real-time data visualization for vehicle operators. 
Diagnostic Tool DevelopmentTechnicians & Service PersonnelInterprets diagnostic trouble codes (DTCs) and other diagnostic information on the J1979 network by decoding raw data into human-readable information. 
Data Logging and AnalysisEngineers Configure data loggers that record J1979 network activity over time to identify patterns, troubleshoot issues, and optimize vehicle performance and fuel efficiency. Contact our sales teamLearn more about SAE J1979® DBC
