Abstract: With the continuous development of the automotive industry, insufficient testing and validation during the product development phase have hindered the implementation of end of line test (EOL) procedures for complete vehicle inspection. To address the production issues caused by software-related electrical inspection problems during the trial production phase, as well as the lack of EOL diagnostic verification tools in the V-mode development process of vehicle development, this paper carries out the design and implementation of an EOL diagnostic tester based on unified diagnostic services (UDS) communication. Based on an analysis of the current state of industry EOL diagnostic testers and production base EOL testing, the EOL diagnostic tester is designed and developed. The interface of the EOL diagnostic tester is designed, and the hardware and software solutions for the tester are developed. Controller EOL verification is conducted through simulation testing and real vehicle testing. The research results show that the EOL diagnostic tester can achieve functions such as controller configuration file writing, module information reading, configuration word writing, system calibration items, static function testing, fault code clearing, and fault code reading. It can be used to avoid EOL issues caused by controller software during the development phase, providing a research approach for researchers in the field of EOL verification.
