  • elm 327 interface with laptop problem

    Hi all.

    I have bought a elm 327 interface to use on my laptop. I have installed easyobdII version 2.2

    I have succesfully linked the interface with the computer.

    When i link to my 55 plate citroen C4, it say linked, then "car bus ok". The next step then stops and says "no power/vehicle response".

    The program then stops scanning.

    Does anyone know why im having this problem and have any idea on how to solve it?

    Thanks for reading

    Most likely, the car is not EOBD compliant.

      Thanks for the reply. Is there anyway to make it compliant or can i get other software that is more suitable?

        With 55-plate you mean model year 2005? That should be compliant, even when it's a diesel. I suspect your interface is the problem. Check it on other known compliant cars.
        Petrol passenger cars 2001 and up. Diesel passenger cars 2004 and up.

          Sorry, yes. 2005. Its does respond to the interface to a certain stage then says the vehicle wont respond.

          Are there any interfaces i could download that may work better?

            What elm scantool are you using? Is it a name brand or one of the cheap units? A lot of the cheap units have issues communicating with some vehicles.

              With interface I mean the elm 327 cable/interface.
              Only solution is to buy another one.

                    I bought a cheap one, too, and it doesn't work with my Mazda6. It does work with two other cars that we have at the house, a Toyota Corolla and a Honda Odyssey. I need to try it in another 6 to confirm it's not just mine, but apparently different cars react differently to cheapo OBD2 readers.

                      Do you know whether the EOBD legislation applies to hybrids and electrics?

                      There are different variations of the Citroen C4, though I'm sure if it wasn't gas or diesel powered the OP would have mentioned it.

                        Yes. Hybrids should also comply. Have to check for the first year, but it's no later than 2003 for a petrol/electric. A petrol/electric hybrid I think falls under petrol - so I think 2001. A diesel/electric falls under diesel - so I think 2004. That's for passenger cars. Normal rules for commercial vehicles also apply. Exception for hybrids is that with the MOT-tests you do not have to measure CO. Obviously because the petrol engine would not fire up.

                        Only exception would be a vehicle with natural gas as main fuel. That may have an extension up to 2006.

                          Vehicles with NG or LPG became compliant between 2003 and 2007.
                          See: http://eur-lex.europa.eu/LexUriServ/...1L0001:EN:HTML
                          The rules for Petrol and Diesel:

                            Thanks! I remember seeing these documents several years ago, but I don't think they had provisions for anything other than petrol and diesel.

                            Do you know where they define "vehicles of category M1"?

                              Exact definition is somewhere hidden in the EU documents, not related to EOBD I am afraid.
                              As far as I know: M1 are passenger cars.
                              N1 are commercial vans (Think Mercedes Sprinter but also Peugeot Expert or VW Caddy).
                              Class I = empty weight < 1205kg, Class II = empty weight 1205 – 1660kg, Class III = empty weight > 1660kg

                              The documents are changes to the original documents from the seventies.
                              The NG and LPG exemptions are defined in 2001. Since then there have been numerous other changes.
                              The big problem is that you can't download the document as it is today.
                              You have to download the original 40 year old document and 40 years of changes (or changes to the changes).
                              Hope you have a sufficient supply of aspirins.
