The i-HDS (Honda Diagnostic System) software suite, developed by Honda, is a comprehensive tool for diagnosing, repairing, and reprogramming electronic systems in Honda and Acura vehicles. This software grants access to all vehicle systems, including the immobilizer security system (requiring a Security Professional level subscription and VSP registration with NASTF). i-HDS empowers technicians with advanced capabilities for complete vehicle maintenance and repair.
Understanding i-HDS Requirements
To utilize the i-HDS software, a subscription and a compatible Vehicle Communication Interface (VCI) are necessary. The VCI, compliant with SAE J2534-1 and J2534-2 standards, facilitates communication between the software and the vehicle.
PC Requirements for i-HDS
i-HDS demands specific PC specifications for optimal performance. The following table outlines the minimum and recommended requirements:
| Requirement | Minimum | Recommended |
|---|---|---|
| Operating System | Windows 10 Professional (32/64bit) | Windows 10 Professional (64bit) |
| Processor Speed | 2.1 GHz Intel/AMD | 2.6 GHz Intel/AMD |
| Memory (RAM) | 4 GB (32bit) / 8 GB (64bit) | 16 GB |
| Storage Drive | SSD with 40 GB Free Space | NVME SSD with 60 GB Free Space |
| Video Resolution | 1366 x 768 or higher | 1920 x 1080 |
| Network | 1 Gigabit Ethernet or 802.11ac WiFi | 1 Gigabit Ethernet or 802.11ac WiFi |
| USB Ports | USB 2.0 Type A | USB 3.1 Type A |
| Bluetooth | N/A | Bluetooth 4.2 or higher |
A faster processor, ample RAM, and an SSD are crucial for smooth operation, especially for tasks like snapshot gathering and live data viewing. Sufficient storage accommodates software updates and data logging.

Vehicle Communication Interfaces (VCIs) for i-HDS
While i-HDS supports generic SAE J2534 compliant VCIs, Honda recommends the Honda Antares Capsule (HAC) for optimal performance and support.
The following table lists VCIs compatible with i-HDS:
| Manufacturer | VCI Name | Notes |
|---|---|---|
| Bright Star Eng. | Honda Antares Capsule (HAC) | Officially supported by Honda for diagnostics and reprogramming. |
| Bosch | MDI2 | Used with GM Techline Connect for 2024 Honda Prologue and Acura ZDX. |
| DENSO | DST-i | Legacy VCI, superseded by the HAC. |
| DENSO | DST-nano | Legacy VCI, superseded by the HAC. |
| OPUS IVS | MongoosePro Honda | Independently validated, but Honda doesn’t provide ongoing validation or support. |
| Dearborn Group | d-briDGe Pro | Independently validated, but Honda doesn’t provide ongoing validation or support. |
ECU Reprogramming with i-HDS
The i-HDS suite includes the Honda ECU Reprogramming application, replacing the older J2534 Rewrite application. This application, compatible with SAE J2534 compliant VCIs, is essential for reprogramming ECUs in Honda and Acura vehicles. Consult service bulletins for specific instructions and model compatibility.
Important Reprogramming Notice
Exercise extreme caution when reprogramming. Only qualified technicians using proper equipment and procedures should attempt reprogramming. Unauthorized or incorrect procedures can cause irreversible damage.
Ensure a fully charged battery and stable voltage during reprogramming. Disconnect any unnecessary electrical loads and maintain secure tool connections. Always refer to the latest software and service information for detailed instructions. Contact Honda for the most up-to-date information and resources.
