In the field of vehicle electronics development and vehicle diagnostics there are many OEM-specific applications that communicate with ECUs. If these applications are based on proprietary communication solutions, exchanges between communication components involve considerable effort. A modular and reusable solution can help here to save on costs and development effort. The SAE J2534 PassThru standard defines a common communication driver that can be used for ECU diagnostics and ECU reprogramming.
