The Honda Ihds (Integrated Honda Diagnostic System) software is essential for diagnosing, repairing, and reprogramming Honda and Acura vehicles. This comprehensive guide dives into iHDS, covering system requirements, VCI compatibility, and the ECU reprogramming process. Understanding iHDS is crucial for any technician working with these vehicles.
Understanding Honda iHDS Software
i-HDS provides access to all Honda and Acura vehicle systems, enabling in-depth diagnostics and repairs. Accessing the immobilizer security system requires a “Security Professional” level software subscription and Vehicle Security Professional (VSP) registration with the National Automotive Service Task Force (NASTF). i-HDS utilizes a subscription model, offering various options to suit individual needs. A compliant SAE J2534-1 and J2534-2 pass-thru Vehicle Communication Interface (VCI) is necessary for communication with the vehicle.
iHDS System Requirements
Smooth i-HDS operation depends heavily on meeting the minimum PC requirements. While minimum specs allow basic functionality, the recommended specifications ensure optimal performance, especially for tasks like snapshot gathering and live data viewing.
| Requirement | Minimum | Recommended |
|---|---|---|
| Operating System | Windows 10 Professional (32/64-bit) | Windows 10 Professional (64-bit) |
| Processor | 2.1 GHz Intel or AMD | 2.6 GHz Intel or AMD |
| RAM | 4 GB (32-bit) / 8 GB (64-bit) | 16 GB |
| Storage | 40 GB SSD | 60 GB NVMe SSD |
| Video Resolution | 1366 x 768 | 1920 x 1080 |
| Network | 1 Gigabit Ethernet or 802.11ac Wi-Fi | 1 Gigabit Ethernet or 802.11ac Wi-Fi |
| USB | USB 2.0 Type A | USB 3.1 Type A |
| Bluetooth | N/A | Bluetooth 4.2 or higher |
A Solid State Drive (SSD) significantly improves booting time and overall i-HDS responsiveness. Adequate storage space is crucial for software operation, snapshot storage, log files, and future updates. A faster single-thread processor directly impacts the speed of data processing within the i-HDS software.
Required Websites and Ports for iHDS
i-HDS requires access to specific websites and ports for seamless functionality. Ensure your network configuration allows communication with these essential resources.

Vehicle Communication Interfaces (VCIs) for i-HDS
While i-HDS supports generic SAE J2534-1 and J2534-2 compliant VCIs, Honda recommends the Honda Antares Capsule (HAC) for optimal performance and compatibility. Honda ensures the HAC interacts safely and efficiently with i-HDS for both diagnostics and reprogramming.
| Manufacturer | VCI Name | Firmware Version | J2534 API Version | Notes |
|---|---|---|---|---|
| Bright Star Engineering | Honda Antares Capsule (HAC) | 1.06* | 04.04 | Officially supported VCI for Honda and Acura dealers in North America. |
| Bosch | MDI2 | 🡪 | 🡪 | Used with GM Techline Connect for 2024 Honda Prologue and Acura ZDX. |
| DENSO | DST-i | 2.02.0002* | 04.04 | Legacy VCI, superseded by the HAC. |
| DENSO | DST-nano | 2.02.0002* | 04.04 | Legacy VCI for Honda Canada, superseded by the HAC. |
| OPUS IVS | MongoosePro Honda | 1.9.5** | 04.04 | Independently validated, but Honda does not provide ongoing validation or support. |
| Dearborn Group | d-briDGe Pro | 3.303** | 04.04 | Independently validated, but Honda does not provide ongoing validation or support. |
* Versions may be superseded. Current i-HDS subscribers receive the latest supported versions.
** Version used in the validation program.
ECU Reprogramming with i-HDS
The Honda ECU Reprogramming application within i-HDS replaces the older J2534 Rewrite application. This application, compatible with SAE J2534 compliant generic VCIs, is mandatory for reprogramming any compatible Honda and Acura ECUs. While the table below outlines legacy ECM/PCM reprogrammablity, later models may have other reprogrammable ECUs like ABS or VSA. Always consult service bulletins for specific instructions.

Important Reprogramming Notice
Only reprogram a control unit/module when directed by a service procedure or Honda/Acura Service Bulletin. Reprogramming should be performed by trained professionals using proper equipment and procedures to avoid damage. Unauthorized programming can cause irreversible damage and void warranties. Always use the latest i-HDS software version and ensure a stable power supply during the process. Refer to service bulletins for specific model instructions and precautions. A fully charged battery and secure connections are crucial for successful reprogramming. Interruptions can lead to failure or damage.
