Diagnostic Tool Itemized List for Mixed DTC and PID Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic tools for vehicles often struggle to efficiently acquire and present all relevant diagnostic data, including diagnostic trouble codes (DTCs) and parameter identifiers (PIDs), in a cohesive manner, making it difficult for users to effectively service vehicles.
Innovation Solution
A diagnostic tool method that establishes a data connection with a vehicle communication interface (VCI), requests and receives diagnostic data, and populates an itemized list using a human-user interface (HMI), incorporating both DTCs and PIDs to provide a comprehensive view of a vehicle's functional conditions, allowing users to efficiently service components and systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a diagnostic tool uses multiple forms of diagnostic data (DTCs and PIDs) to relay information, then the comprehensiveness of diagnostic information is improved, but the complexity of data processing and presentation increases
Solution Approach 1:
The diagnostic data is segmented into distinct types (DTCs and PIDs) and processed through separate identification pathways. The system identifies whether received data is a DTC or PID, then routes it to appropriate processing logic, making the complex data handling manageable through structured segmentation
Solution Approach 2:
The diagnostic tool acts as an intermediary that receives raw diagnostic data from the VCI, processes and standardizes it into a unified format, and presents it through the HMI. This intermediary processing layer transforms multiple data formats into a cohesive presentation without requiring the user to manage the underlying complexity
2Ease of operation
If a diagnostic tool presents all relevant diagnostic data in a cohesive manner, then the ease of operation is improved, but the time required to acquire and process data increases
Solution Approach 1:
The system performs preliminary actions by establishing a data connection with the VCI and proactively requesting diagnostic data before the user needs to analyze it. The diagnostic tool automatically retrieves both DTCs and PIDs, processes them into a unified format, and prepares the cohesive presentation in advance, saving time during the actual diagnostic process
Solution Approach 2:
The system merges multiple data acquisition operations into a single cohesive process. By requesting and receiving both DTCs and PIDs through one integrated data flow, and then combining them into a unified presentation, the system reduces the total time required compared to separate acquisition and processing of each data type

AI summary
A method for acquiring diagnostic data from a vehicle communication interface and providing the data to a user of a diagnostic tool as an itemized list. The diagnostic data comprises mixed types, such as diagnostic trouble codes and parameter identifiers. The user may utilize the diagnostic tool to filter or sort the diagnostic data according to elements associated with each entry of diagnostic data in an itemized list.
