ECU Diagnostic Software Development
ECU Diagnostic Software Development is the process of implementing and integrating the diagnostic functions in an Electronic Control Unit (ECU) to support vehicle fault detection, troubleshooting, monitoring, and software flashing. It ensures that an ECU can report internal issues, communicate with diagnostic tools, and comply with global standards such as UDS (ISO 14229) or OBD-II.
This is a critical part of after-sales serviceability, production testing, in-field maintenance, and over-the-air (OTA) support — especially in modern, connected vehicles.
ECU Diagnostic Software Development
Based on ISO 14229, these services allow the tester (e.g., a garage tool or cloud system) to communicate with the ECU:
- Diagnostic Session Control : Initiates different ECU sessions (default, programming, extended)
- ECU Reset: Triggers ECU soft or hard reset
- Read Data by Identifier: Reads runtime or calibration parameters
- Write Data by Identifier: Writes parameters like VIN, configuration
- Read DTC Information: Retrieves fault codes stored in the ECU
- Security Access : Prevents unauthorized access to critical functions
- Request Download/Transfer Exit: Enables software flashing or reprogramming
We provide Consultancy and development services for TCU /ECU diagnostics.
