Technical Obd - help me!!

[DanielSigsgaard]

Hi guys
Im new in this forum but I have a urgent issue. Please excuse my english - Im from Denmark
I just but a very nice Multipla, 1999, 100 1.6 16v. It is very well kept and drives very good. When you have many kids then the car is extremely practical.
I have noticed a big fuel use. There is a sensor on the very beginning of the exhaustion - in danish its called a "lambdasonde". It measures the outlet of the engine. It has 4 wiring, but on the main plug-connection 2 wires are out of the plug, like if somebody has pulled in the plug.
So before I modify anything I would like to put a diagnostic scanner to my car to see if there are more problems.
I can see that there is a OBD-socket under my steering. I just but a KIWI WIFI interface and REV2 for my iPhone, but it has problems with connecting. Then I bought a scanner U480, but that one can't connect either.
And now I'm desperate. I really would like for the REV2 to work...
Does anyone know what scanner etc that will work for my car? It has the OBD-socket so I should be able to connect to the ECU somehow.
I also just read that on Fiat there are some adapter-plug..but is that necessary when you have a OBD-socket?
When I used the KIWI then I made a WIFI connection and that one is proper set. And when opening the REV2 it finds the Wifi. Sometimes it connects for like 10 secs, and the to disconnect...
As I said - Im a little desperate because I have put in my mind to make it work

Have you tried www.fiatecuscan ?.. It's free!!
A laptop and a cable along with that should read and clear any errors....

 

[DanielSigsgaard]

Ok? I have never heard about it, but I'm gonna look into it Now I just have to find out if I can use the OBD-socket in my car? But I should be able to..

 

[martyc5674]

Yes it works on mine... You need a USB to obd cable...fiver on eBay!!

[DanielSigsgaard]

Cool
So you have a 99? Did you use an adapter cable? I saw on their homepage that there are 3 different cables,,

 

[martyc5674]

Mine is 03... Is the connector under your steering wheel 16 pin??

One if these will work if so eBay item 300675663951

I was just thinking..If I find out the right adapter-cable shouldn't I the not be able to plug in my KIWI Wifi?

Couldn't tell u that I'm afraid....

 

[DanielSigsgaard]

Ok
Thanks a lot for ur feedback. Im gonna try it out, I also have my U480 scanner to test it on. I will post the results tomorrow

The "lambdasonde" or lambda sensor in English is to tell the ecu how much oxygen is left in the exhaust gases so it can adjust the mixture. It has four wires, two are thicker and supply 12v to a heater inside the sensor, two are quite thin and are the voltage signal it gives ( which vary between 0 and 1 volt). All these cables need to be connected so that is a problem straight away. You don't need to scan just yet. Get them connected back up in the correct positions and start from there.
Hope that helps

 

[DanielSigsgaard]

Thanks for that answer. I have been looking everywhere to find out what the wiring do/ are for. Yes, Im gonna connect tomorrow and hopefully thats the reason to the big use of fuel

 

[DanielSigsgaard]

..I mounted the lambda-sensor and it sounds and drives a lot better. So a big improvement on that one..

Then I tried to modify my KIWI WIFI so that it would fit as a adaptercable as they are showning you on fiatecuscan
I tried all 3 choices but my KIWI would still not work. So today or tomorrow i am going to try it on my U480, so if someone know that it wont work then feel free to post it ..would save me a little time

Surprised the U480 doesn't work, I have one which worked on both my Multi's 2002 and 2005 1.9's?
Protocol is KWP2000? However, when I plugged mine in it automatically ran through the different protocols and used KWP2000, have you tried the U480 on another car in case it is faulty?

 

[DanielSigsgaard]

ja - when I tried it on my U480 it ran through all the protocols, and it wrote error at the end, I think it was linking error..But after that I was told that I needed an adaptercable (fiatecuscan) where there are 3 kinds of cables to choose from. Have tried it on my KIWI WIFI - didnt work, so now im just gonna try it on my U480..

 

[DanielSigsgaard]

Maybe it doesnt work because it a old car? 1999..
But hopefully it will work with the adaptercables.

 

[momoe]

U480 is a dedicated OBDII reader and plugs into the OBDII interface, it either works or it doesn't - that's why I suggested trying it on another car to check it's working. It may be that the U480 is faulty or the OBDII on the car isn't working?

Fiat ECUScan is a program for laptop's which needs the correct interface cable between the car and the laptop, ECUScan provides realtime data which is useful when trying to work out what is happening, it is a lot more than a simple OBDII reader.

 

[DanielSigsgaard]

No - I havent tried it on an other car. I just asumed from fiatecuscan that when you have a model like me then u would need an adaptercable to plug in between ur interface device and ur OBDII.
How do I find out if the OBD-socket is working? When I have my KIWI WIFI on then it sometimes connects for like 5 secs, and then disconnects, and when I use the U480 then it reads through all the protocols and writes error at the end..thats why I thought it needed an adaptercable..

 

[momoe]

I'd test the U480 on another car first, if it runs through the protocols and connects then I'd assume the U480 is fine. I'd also try to test it on another Fiat or Opel to try and check whether the KWP2000(?) protocol is working, if this works then I'd be suspicious of the OBDII in your car.
Maybe try and find another known working OBD tester that you test your OBDII with?

 

[Juggers2k]

If the U480 is an OBD-II tool it's not going to work on a 1999 car in Europe. OBD-II only applies to cars sold in north America. The European equivalent is EOBD, which came into force from 2001 for petrol cars and 2004 for diesel cars registered from new within the EU (and later for heavy 4x4's and commercials).
FiatECUScan should work as it uses Fiat's own diagnostic software protocols - it doesn't rely on the car being standards compliant.

 

[DanielSigsgaard]

I think you are right. I just tried the U480 on my brother Chrysler Voyager from 96, and it worked with no problems. I also discovered that on my brothers Chrysler there is a self-test diagnostic way, by holding down trip and reset and starting the car.. Do you know if there is a similar way on a Multipla?
