The SAE J2534 Pass-Thru APIs (Application Programming Interfaces) provide a standardized set of software interfaces that allow software applications to communicate with automotive Electronic Control Units (ECUs) using a pass-thru device. These APIs provide a common language that independent repair shops and vehicle owners can use to reprogram ECUs without having to go through the original equipment manufacturer (OEM).
Customer background
Our partner is a leading NAM Aftermarket supplier specializes in automotive software development tools, Worked closely with the SAE J2534 committee to develop the APIs, which were then implemented in current current design.
Challenges
Design and Development of universal diagnostic and reprogramming SAE J2534 pass-thru interface that supports all the major OEMs, as well as aftermarket and J2534-based protocols.
Product and Solution
The solution involves design and development of Hardware, Firmeare and SAE J2534 Pass-Thru APIs for J2534/1/2/3 API versions
Tools & Technologies
Delivered Services
Perasia built a team of technical experts involved in a comprehensive approach in hardware design, firmware development, integration with OEM software, testing and validation, and production and distribution.
The software and hardware design of a J2534 pass-thru device includes the following component.
1. Requirements Analysis: Analyze the requirements of the J2534 standard and determine the necessary software interfaces. This involves working closely with our partner to ensure that the APIs meet all the necessary specifications and requirements.
2. API Design: Design the API specifications and develop the necessary software libraries. The APIs are flexible and adaptable to different pass-thru devices and ECU protocols, while also being easy to use and integrate with existing software applications.
3. API Implementation: Developed the necessary libraries and functions to provide the desired functionality. The implementation is efficient and robust to ensure that it works reliably in a wide range of situation.
4. Testing and Validation: The APIs are thoroughly tested and validated to ensure that they meet all the necessary performance and reliability standards. Tested with a wide range of pass-thru devices and ECU protocols, as well as tested with different software applications.
5. Integration with Diagnostic Tools: Integrated with diagnostic tools such as CANape and CANalyzer to allow users to access the pass-thru functionality directly from thrid party vendor tools, providing a streamlined and user-friendly interface for diagnostic and reprogramming operations.
6. Communication Interfaces: We have implemented common communication interfaces in J2534 pass-thru devices are Ethernet, USB, and Bluetooth to connect to the ECU.
Business Value
1. The resulting device provides a reliable and user-friendly interface for diagnostic and reprogramming operations, and has become a popular choice among independent repair shops and vehicle owners.
2. We provided a flexible pricing model that is based on the scope of the project, which helped our partner to reduce development costs.
3. By leveraging the expertise of our engineers, we reduced the risk of software bugs and errors that can result in costly recalls.
