Abstract: This paper presents initialization of data communication link to vehicle OBDII (OnBoard Diagnostics II) system using a PC-based diagnostic tester. The current work represents the physical layer of a diagnostic tester project. A concise overview of OBDII system is shown at the beginning. Diagnostic interfaces for communication with external testers are investigated. The ISO 9141-2 / ISO 14230 interface has been chosen for implementation mainly because it can be directly interfaced from a PC using simple electrical converter to RS232 (interface adapter). The circuit of the interface adapte
