Q: How do I reprogram the ECU?A: Both HIM clone and genuine can do ECU reprogramming for Honda.Consult the Service Manual for specific model and year.
Some older vehicles may not have the capability.
Q: Does the HDS software package retrieve codes for ABS, AIRBAG, and CHECK ENGINE?Ī: It depends on the year of the vehicle. Q: Will HDS software work with interface devices other than the MVCI, such as J2534 devices, HIM, GNA600, Ford VCM, etc.?A: No, HDS will work with the MVCI and HIM diagnostic tool. You may need to uninstall the other diagnostic software in order to use the HDS. Q: Can I install HDS software and other OEM’s diagnostic software on the same PC?A: This may or may not be possible, depending on the other OEM’s software. When software updates are released, you can get new links on the official blog. Q: How do i get the HDS software and the updates?A: The HDS software download link can be found here. I belive this thing can data log, reprogram gauge clusters, and reprogram the immobilizer for new keys, but have not tried these things yet. I have successfully used the TPMS features, CKP relearn, idle relearn, ECU reset, and cleared DTS faults. The cracked HDS software version that came with it did not cover my car, but I was able to find a newer version (V2.024.05) on the internet that worked. I was hesitant because it did not state that it supported my 2011 Fit. I made a leap of faith and picked one up online, sent from China about two years ago to reprogram my TPMS sensors (I hate you Honda for this TPMS crap system). So if you don’t know there are all kinds of clones of Honda’s HDS HIM diagnostic system out there on the internet. Honda has had several tools, the HIM is two or three generations old, but the newer ones are not cloned yet ( GNA600 & MVCI). HIM is the specific tool (Honda Interface Module). HDS is a general term for Honda’s Diagnostic System. The ECU will power-up with a 2.0 amp power supply but transfer rates will be slow and you will get CRC errors.So I have had a lot of question on my HDS clone setup lately so I thought I would do a bit of a review. If you make a bench harness to work with your ECU you will need a 2.5 amp power supply. For the serial to k-line converter, I recommend the schematic below that uses optocouplers to keep the bike power isolated from your electronics. This code assumes you are using a FTDI based USB to serial converter. The easiest way to talk to the ECU via the k-line is a USB to serial (TTL) converter, and a serial to k-line converter.
