ELM327 Development Test CAN Customization J1939 OBD II English Version OBD Simulator 5-SAE-J1939 Automotive ECU Simulator

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Parameter Simulation: Simulates real-time vehicle data (voltage, RPM, coolant temperature, intake air temperature) for diagnostics without requiring a physical vehicle.
  • Protocol Support: Compatible with OBD-II, CAN, and SAE J1939 protocols, enabling testing across diverse automotive systems and diagnostic tools.

Key features

  • 1. Transparent Acrylic Construction for Enhanced Visibility

    • With a clear acrylic case, you can monitor internal components and real-time data (e.g., voltage, RPM, coolant temperature) directly, enabling seamless troubleshooting without disassembly. This transparent design contrasts with opaque enclosures common in traditional simulators.*

  • 2. Customizable Digital Interface for Protocol Flexibility

    • With a multi-functional front panel and digital display, you can adjust diagnostic protocols (OBD II, CAN, J1939) and parameters on-the-fly, adapting to diverse vehicle systems and testing needs. This interactive design surpasses static simulators limited to single-protocol support.*

  • 3. Multi-Protocol Support for Broad Automotive Compatibility

    • With built-in support for OBD II, CAN, and SAE J1939 protocols, you can test and diagnose a wide range of vehicle models and ECUs, outperforming single-protocol devices in versatility.*

  • 4. Cost-Efficient Controlled Environment Testing

    • In scenarios requiring diagnostics without a real vehicle, the simulator allows technicians to troubleshoot issues in a lab setting, reducing downtime and repair costs compared to on-road testing.*

  • 5. SAE J1939 Compliance for Industry-Standard Accuracy

    • With certification to SAE J1939 standards, you can ensure precise simulation of heavy-duty vehicle systems (e.g., trucks, buses), meeting professional-grade diagnostic requirements.*
