Title: INITIALIZING COMMUNICATION TO VEHICLE OBDII SYSTEM Keywords: OBD, diagnostics, initialization, ISO 9141-2 and ISO 14230Abstract: 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 References - Dzhelekarski, P., Alexiev , D., 2005, ELECTRONICS’05 : Reading and interpreting diagnostic data from vehicle OBDII system, Sofia, Bulgaria, 2005, <Sofia>, TU-Sofia
