i-HDS Diagnostic Software and J2534 Reprogramming Software

American Honda Motor Co., Inc. ("Honda") offers the i-HDS (Honda Diagnostic System) software suite for the diagnosis and repair of electronic systems on Honda and Acura automobiles, and for the reprogramming of electronic control units (including, but not limited to, ECMs and PCMs). This software provides access to all Honda and Acura vehicle systems (access to the immobilizer security system requires a Security Professional level software subscription and Vehicle Security Professional [VSP] registration with NASTF). To use the i-HDS software, you need to purchase one of our convenient subscription options. In addition, you will need a pass-thru Vehicle Communication Device (VCI) that is compliant with SAE J2534-1 and J2534-2 in order to communicate with the vehicle

 

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.

VCI Name	Manufacturer	Version Information		Notes
		Firmware	J2534 API
DST-i	DENSO	2.02.0002*	04.04	This is the current generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device.
DST-nano	DENSO	2.02.0002*	04.04	This is the current generation VCI used by Honda Canada Inc. Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device.
MVCI	Bosch	3.01.60*	04.04	This is the previous generation VCI used by Honda and Acura dealers. Honda routinely validates the functionality and provides customer support for this device.
MongoosePro Honda	Drew Technologies	1.9.5**	04.04	This company has completed an independent i-HDS validation and claims it to function with the i-HDS software. Honda does not provide ongoing validation, nor customer support for this device.
d-briDGe Pro	Dearborn Group	3.303**	04.04	This company has completed an independent i-HDS validation and claims it to function with the i-HDS software. Honda does not provide ongoing validation, nor customer support for this device.

* These versions may have been superseded. Honda provides the latest supported versions to current i-HDS subscribers.
** Version used in validation program. See Terms and Conditions and Important Notice Regarding Reprogramming below for more details.

 

Reprogramming with the J2534 Rewrite Application in i-HDS

Included in the i-HDS software suite is a new reprogramming application called J2534 Rewrite. This application is made available to all subscribers of the i-HDS software suite and replaces the previous generation software, J2534 Honda Pass-thru Reprogramming Software.

This new application is compatible with generic VCIs that comply with SAE J2534. It must be used to reprogram any Honda/Acura vehicle equipped with ECUs that support reprogramming. Refer to the table below for legacy applicability for the programming of ECMs and PCMs. Though system dependent, late-model vehicles may be equipped with other ECUs that support reprogramming as well, e.g. ABS or VSA. J2534 Rewrite must be used to reprogram these control modules, as instructed in an applicable service bulletin.

As shown in this table, not all legacy Honda/Acura models are equipped with a reprogrammable ECM/PCM. Furthermore, all 2007 and later models not listed in the table are fully supported with this application.
