Vehicle EOL Testing Data Processing and DTC Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During vehicle end-of-line testing routines, diagnostic trouble codes (DTCs) and corresponding vehicle network data are not readily available for inspection and troubleshooting, hindering efficient identification and resolution of potential issues.
Innovation Solution
A method that determines if a DTC is issued during the testing routine, stores vehicle network data in a database, identifies a designated agent based on the DTC and ECM-agent directory, and electronically transmits a notification to the agent, providing access to the data and codes without requiring physical access to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicle network data is stored and accessed electronically during EOL testing, then troubleshooting efficiency is improved and time to identify faults is reduced, but system complexity and data management requirements increase
Solution Approach 1:
The system performs preliminary actions by automatically storing vehicle network data in a database during the EOL testing routine before troubleshooting is needed. The ECM-agent directory is pre-populated with mappings between DTCs, ECMs, and agent contact information, enabling immediate retrieval and notification without manual setup during fault resolution.
Solution Approach 2:
The patent introduces an intermediary notification system that acts as a mediator between the EOL testing system and technicians. The system generates automated notifications containing DTC information and links to stored vehicle network data, eliminating the need for technicians to directly access complex vehicle systems or manually retrieve data, thus simplifying their workflow while maintaining data accessibility.
2Loss of time
If automated notification system is implemented to alert agents about DTCs, then response time to faults is reduced, but system complexity and automation requirements increase
Solution Approach 1:
The system implements feedback by continuously monitoring EOL testing results and automatically generating notifications when DTCs are detected. The ECM-agent directory serves as a feedback mechanism that maps DTCs to specific agents, ensuring that the right personnel are notified immediately when faults occur, creating a closed-loop system from detection to notification.
Solution Approach 2:
The automated notification system enables self-service by automatically detecting DTCs, retrieving relevant vehicle network data, identifying the appropriate agent through the ECM-agent directory, and sending notifications without human intervention. This reduces the need for manual monitoring and routing of fault information.

AI summary
A method for processing a vehicle end-of-line (EOL) testing routine includes determining whether a diagnostic trouble code (DTC) is issued during the vehicle EOL testing routine and obtaining vehicle network data generated during the vehicle EOL testing routine. The method includes, in response to a determination that the DTC is issued during the vehicle EOL testing routine, storing the vehicle network data in a database, associating the DTC with an electronic control module from a plurality of electronic control modules, identifying a designated agent from among a plurality of agents based on the DTC and a ECM-agent directory, and electronically transmitting a notification to the designated agent, where the notification provides access to the vehicle network data and the DTC.
