  • Problems with the ELM-327

    I recently purchased the ELM-327 to use it on my 2007 Honda Odyssey, but can't figure out how make it work. The computer I'm using already has the drivers for the ELM-323, so when I plug the 327, the "new hardware found" wizzard does not come on. I believe it's trying to use the drivers for the 323. As a result, I can't figure out a way to install the drivers for the 327. When I plug the 327 to the OBD port using Dashcommand, I get the error message "Error detecting OBD II protocol." Another thing, when it's plugged to the OBD port, only the red (solid red) light comes on. The other lights such as TX, RX, etc. don't come on. They flash when Dashcommand attemps to establish communication.

    Any help is appreciated.

    Thanks,

    ELM323 and ELM327 USB clones use the same FTDI drivers. The error you get means that DashCommand was able to connect to the scan tool, but could not detect the OBDII protocol.

    Where was your Odyssey originally sold (which country)?

      I bought my Odyssey brand new in Maryland, USA. Based on internet searches, I think this model uses the CAN protocol. This is the reason why I bought the 327. Doesn't the ELM327 use VCP drivers apart from the FTDI driver? According to instructions that came with the product, you need both set of drivers, and I can't figure out a way to install the VCP drivers without the "New Hardware Found" wizzard.

        Last time I had to install a VCP, I went to my device manager and found the comport for my device. I right clicked and went to properties. Under one of the tabs in the properties was a check box to install VCP drivers.

          Alex, if he already had drivers for the ELM323, he doesn't need to install a new set for the ELM327: they both use the same IC (FT232R). Also, "Error detecting OBDII protocol" means that DashCommand can talk to the device, but can't connect over OBDII.

          Worst case, use FTClean to uninstall the drivers, and install them again.

            P.S. A 2007 Odyssey bought in Maryland should definitely be compatible. There must be something wrong with the tool.

              Where did you purchase the ELM device from? A reputable dealer, or is it a cheap ebay clone? (How much did you pay for it?)

                I want to thanks everybody for their support. I bought my unit from http://www.mo-co-so.com. They are a good company dedicated to the carputer market with excellent support. I understand that the this unit should work with the same drivers as the 323. Can someone help me with the following:

                1)Do you need the VCP drivers, and if so, how do you install it? I'll try Aberk's advice above and report back.

                2) When the device is connected to the OBD port and the computer, how many LEDs are supposed lit on?

                3) Vitality, what do you mean "something wrong with the tool?" do you mean Dashcommand or the unit?

                Thanks,

                  I tried Aberk's method above and could not find any option to install the VCP drivers. Here are some screenshots I took while checking the device properties:

                            Suit yourself, DominicanJB. ELM327 clones are hit and miss. Sometimes they work great, sometimes they don't work, and sometimes they sort of work (which is worse than if they didn't work at all, this thread is a great example why). So what you buy depends on how much you value your (and other people's) time.

                            Yes, I am biased, but that is only because (A) ELM327 users come to our forum for support in droves (because the clones ship with ScanTool.net v1.13 software and people think we're the manufacturer) and (B) the tools I recommended, pass a rigorous quality assurance check. I know this, because I helped design and build the testers, write the test scripts, and put together the test procedure.

                            I can totally sympathize with people who are trying to save money, and I don't blame you for buying the cheaper alternative. You can console yourself by the thought that your experience may help other folks to avoid the same mistake.

                              Heh, for $5 more you could have gotten support from the maker right here. I have the same clone. Mine reports version 1.5a which doesn't exist, so my software has a special case to revert to 1.2 specs which is all it supports. Who knows what all of them report. It's enough work to keep up with ELM. But just like overstated battery capacities and SD cards, China is number one.
