    Sorry not familiar with any 3 pin code reader we only use the OEBD11 socket for diagnostics and code reading:Smile:
    Geo
    This lead HERE will allow you to use a standard code reader to read from the 3 pin socket if that helps

    i found that lead on ebay yesterday but i have read someware that it will not work with an obd2 reader,

    i can get the software for the laptop of the fiat forum and then need an obd1 lead to connect to the laptop and the 3pin adapter lead , i am not sure which to buy.
    thanks for your help

    update

    i am now able to read the codes from the ecu on my 2.8jtd with the fiatscan 1.6 software and leads from ebay, details can be found here

    http://www.fiatforum.com/lets-talk-fiat/219467-free-fiat-diagnostic-software.html

    and then read the how to use procedure here

    http://fiatecuscan.net/Default.aspx

    i have cleared one error code but another remains P0480 which is cooling fan #1 malfunction , does anyboy know if there are any fuses for this ,i know where the relay is but want to start with the simple things first

    Then start with the fault as indicated by the code--- faulty motor, poor conections
    Code PO485 indicates a power or earth fault:Doh:
    Now you have your reader all you have to learn is code interpretationn:Eeek: and its a nightmare, as you learn to interpet the codes it will start telling you lies, then you will soon learn that senor errors as indicated are false and its a hole in the exhaust thats causing the error code:cry:
    Have fun:thumb:

    As an add on
    We have many customers that have bought code readers ,it can sometimes save you the cost of a scan, but if not used correctly it can be used to clear other codes that would otherwise help the Mechanic to trace and interpret the correct fault, thereby doubling the diagnostic cost by seding him up the wrong path
    We in the trade just love self diagnosis
    It usualy goes somthing like
    Can you fit me an offside ball joint
    Q why?
    Ive got a knocking noise
    Q are you sure its the ball joint
    Yes
    Ok tha'tl cost you £XXX
    Ball joint fitted and by the way it still knocks:Eeek: its your anti roll bar link rod :Doh:
    experiance has taught us never try and point out a self diagnosis could be wrong, you get some very annoyed customers
    Buying a code reader is a bit like going to spec savers for glasses to teach you to read

    That said, practise and you will get pretty good at it:thumb:
    do a lot of internet reading about code reading methods and interpretation, you could then put some garages to shame:Sad:
    Or at the very least know when your being bull s**tted:thumb:
    Knowledge is power:BigGrin:

    cheers Geo, the other code was a glow plug warning which has not returned . I used the fiat scan to check the cooling fans and could get fan 2 running but not fan 1 which the code points to , i intend to swap the relay and then recheck, the fan is free spinning so its not seized , checking the internet for this code brought up a peogeut boxer amendment about the relays causeing this code and the warning light , to rectify was to change relays.

    once the engine gets to temp the warning light goes out for a while then reapears for a while before going out againwhich makes me think a sticking relay any thoughts on this please

    You could be spot on you may be miles out
    If you have an identical relay then swop it
    The point I was trying to make was dont get to rely on the codes as a given, very often a failed unit is no more than a conection problem at either end ie the sensor or ecu,
    I would have started by giving the fan a feed then work back,but its horses for courses, youll get there in the end
    Good luck and happy scanning:thumb:
    the more you play the more you learn, Im still learning after all these years

    Would have a starting handle, and points and condenser:Laughing:

    I still have this problem of the injection light on for code P0480, the light is on all the time , i have connected 12volt to the fan direct and it runs ( so not a faulty fan ) i have swapped the relays behind the cover on the radiator and still have the same problem , where is the sensor for the tempreture to turn the fans on any can any body give me any other ideas to try , its been to a garage for 4 hours with no joy and we are off to scotland next weekend for 3 weeks

    thanks
    chris

    This reads like a circuit prob, as Geo said I think. Have you gone round all connectors etc and checked them? If you let the van idle (watching the temp guage) does fan #1 come on? Is fan #2 kicking in?

    If fan #1 doesn't run stick a multi meter (in theory) accross the fan socket (ie from the power side not the fan) and see it 12volts turns up at all, is 12 or less or none etc, proves fault conclusivly either way.

    Fundamentalty, does the van overheat or try?

    i have been out and removed the battery to get to all the big fuses behind it, they are all ok ,fuses checked in the glove box all ok are there any more fuses or realys to check

    i have undone all the connections that i can get my hands to and remade them , the engine does not seam to overheat and the gauge never gets above half way,

    i will take the van for a run to get up to temp and then watch the fans
    thanks for replys
