Problem odometer Alfa 147 Mile (1.6 Ts 105

[ecucilacunta]

Hi to all,
today I have brought a 147 1,6 ts 105 of 2001. The customer has to sell the car, but he has had problems since? the odometer does not show the miles. In fact, instead of the km sprout 6 dashes.
I made the diagnosis with texa axone 2000 and resulting errors can in the body. I tried to make the adaptation odometer and replacing the dashboard, but to view the km does not want to learn.
The instrumentation ? fully functional and also the km partial work. Through the diagnosis, I read the km 1048557 and I assume that the 7 are the meters(I have never seen an alfa engine to gasoline to make a million kilometres). Pu? maybe there is a problem of communication with the body? Or it could be a problem of the speedometer.
I would like to mention also that the customer has purchased it so? with the odometer not working.

No one knows anything about this problem?

[legendaryslave]

you ? messed up the micro or the e2p depends on the number of the picture you need to make a rewrite with another file taken from a having the same number and adapt proxi and km

[ecucilacunta]

Can you explain what I need to do and how. I am a beginner. I need instrumentation?

[legendaryslave]

postami the number of the picture, however, need a dedicated right at the limit you can take a picture of a demoman and align the proxi

[ecucilacunta]

In the end I had more? way to continue to work on the machine in question why? the customer has sold so well? as it was. Shame I would have liked to be able to solve the problem. Thanks for the support .

hello,
I open this discussion as it is happening to me the same problem. The same car picture VDO no. 11000 896 8001 - FIAT 735 290 188.
What should I do? I have the UPA and other chip programmer but I don't know what component to read and change the file to be rewritten.

[fabius8585]

gimarras if you have not solved the problem let us and we'll help you gladly to solve,you have to unsolder the eeprom 93c86 and read it then with the change of the file to rewrite, I'll help you

[gimarras]

Thanks Fabius. Now I'm on vacation when I come back you contact.

[fabius8585]

Gimarras I better controlled through codes VDO FIAT and the eeprom mounted on your instrument panel is an Nec uPD78,I also have the eeprom available,just tell me the mileage report and can you please post the file ready to write.

[gimarras]

Very helpful. Now I'm on vacation, it is the machine of my sister, soon return, I try it. I hope to be able to read the chip, use a player chinese TL866 and the UPA. Then I'll let you know. The Km that I had read in diagnosis were about 97 thousand, and then 104 thousand would be good. Just rewrite, or do you think it is the case of changing the physical component (Nec) ?
Meanwhile, Thanks then I'll let you know.

[fabius8585]

you simply have to rewrite,if you have the mileage accurate I am writing to you to precise.

[gimarras]

OK, fabius, soon return, I read the chip, then we feel. In the meantime, thanks

[fabius8585]

please imagine

[fabius8585]

hello gimarras still nothing?let me know

[gimarras]

hello Fabius, unfortunately I can not still get their hands on it, as soon as I can if you're still available I'll contact you.

[gimarras]

Hello fabius, at the end I was able to open the the odometer, but by controlling the components I can't find the 93c86. the only eprom is signed 2903 ST 9209. And a' that ? Can I dissaldarla, to read and rewrite the file that I had the past?
Thanks

[gimarras]

The chip 2903 is on the high side under the tachometer.

[gimarras]

OOOPPss. I have read better split my framework would have the processor the NEC. I read the acronym 780826GC-060. and' what? I have UPA but I don't think it is easy to read and risaldarlo. I have the station dissaldante the solder, but a chip with all these legs I've never done it. You say I try?

[fabius8585]

Hello Gimarras,if you have the soldering station dissaldarlo is a moment.In any case, with the upa, you should be able to read it,I use TL866A and I have different facts.I can not tell with precision whether the agreement 780826GC-060.If you can post the photos here I say what it is.If you re-read a few previous post I have posted the file already modified.IF you have any problems let me know.

[gimarras]

Thanks Fabius. You had seen the file that I had sent. I attach the photo of the odometer . The NEC chip is the middle one with the initials that I have indicated ? I also use the TL866A but I don't think I have the adapter for that chip. Which one do you use? Thanks

[fabius8585]

Hello Gimarras,forgive me for the delay,then I've done a bit of confusion,the Nec chip is the one with the initials that I have indicated,only that it should be read with Upa, and not with the TL866A.

[gimarras]

Me know please specify what is the adapter to use with the UPA? I think that he had those in the KIT, they sent me the yellows. If you send me the image I can see of buying it. thanks
