Abstract - The Pocket OBD DataLogger project focuses on creating a compact and cost effective device that can measure critical vehicle parameters, including the State of Charge (SOC), Battery Health, and Vehicle Identification Number (VIN), during the Pre-Delivery Inspection (PDI) phase. This system aims to replace the traditional, expensive Multi-Function Tester (MFT) with a more efficient alternative. By using an Arduino UNO R3 microcontroller with a CANBUS shield, the device retrieves vehicle data within 3 seconds, displaying the information on an LCD and saving it to a Micro SD card for future reference. This project significantly enhances the efficiency of car inspections, automating the process of measuring electrical parameters before vehicle dispatch. With a total cost of approximately INR 10,000, it presents a more affordable solution than conventional MFT devices, while still maintaining accuracy and reliability. The report details the hardware and software components, system design, and testing processes, offering insight into the development and operational advantages of the Pocket OBD Data Logger.
