Optimization of automotive diagnostic systems

Authors

Abstract

The increasing complexity of modern vehicular systems has demanded advanced methods for precise data diagnostics and monitoring. The on-board diagnostic (OBD-II) protocol and associated devices, such as the ELM327, have been essential for this purpose but faced challenges regarding stability and accuracy. Therefore, the study optimized and evaluated a vehicular diagnostic system using the modified ELM327 and PCMSCAN to improve the accuracy of OBD-II data analysis, thereby enhancing vehicle performance and safety. The methodology involved using the modified ELM327 with a USB connection to ensure stability in data transmission. On-board diagnostic Parameter Identifiers (PIDs) were configured and monitored to evaluate live data collection under various operating conditions. The results demonstrated a significant improvement in the stability and reliability of data collection, surpassing the limitations of conventional methods. The accuracy in data acquisition and the ability to monitor real-time parameters were validated by providing detailed information on vehicle performance and safety. In conclusion, the integration of the modified ELM327 and PCMSCAN represented a significant advancement in vehicle diagnostic technology. This combination offered a robust solution for OBD-II analysis, enabling more precise diagnostics and contributing to greater vehicle efficiency and safety. Additionally, it facilitated the opening of opportunities for future research in telematics and predictive maintenance.Keywords: On-Board Diagnostics Parameters, Reliability, Predictive maintenance, Automotive technology.
