<div class="section abstract"><div class="htmlview paragraph">Software complexity of vehicles is constantly growing especially with additional autonomous driving features being introduced. This increases the risk for bugs in system, when car delivered. According to a manufacturer, more than 90% availability problems corresponding Electronic Control Unit (ECU) functionality are either caused by software or they can be resolved applying updates overcome hardware issues. The main concern sporadic errors which not caught during development phase since their trigger condition too unlikely occur covered tests. For such systems, there need safe and secure infield diagnosis. In this paper we present tool architecture remote access, facilitates standard read/write an efficient channel interface communication file I/O, continuous trace. enables access latest automotive Microcontroller Units (MCUs)’ trace provide non-intrusive system observation without compromising safety, security, real-time performance. designed that physical agnostic tool. A target connected any as well Ethernet. With today’s increased silicon performance, Ethernet viable option interface, from field. implementation includes agent firmware run on application core sand-boxed sub-task security core. next generation vehicles’ E/E architectures moving towards backbone, gives developers include systems hardware.</div></div>
