i-HDS Diagnostic Software and J2534 Reprogramming Software
Honda J2534 Pass-Thru User Guide
Honda J2534 Pass-Thru Software Download
Vehicle Communication Interfaces (VCI)
The i-HDS software supports the use of a generic pass-thru VCI that is compliant with SAE J2534-1 and J2534-2. However, Honda recommends the Denso DST-i or the Bosch MVCI for use on Honda and Acura vehicles, as Honda has worked closely with these manufacturers to ensure their hardware and our software interact safely and within the J2534-1 and -2 specifications, for both diagnostics and reprogramming. If you choose to use a generic VCI, please carefully consider the customer and technical support options you will receive from your chosen device supplier. Honda does not provide technical or customer support for generic VCI devices.
The VCI Application Table below lists devices that either are approved and supported by Honda or are known to have completed and passed an independent, exhaustive validation program with our i-HDS software suite.
