Alfa Romeo 147 2001 NEC Dash

[julianstefanov]

Hello,

Can someone please help me a bit? I have Alfa Dash with Nec CPU and also I have Nec Programmer, but I can't find ALFA in the list of vehicles:

 

 

Is there a picture or some kind of info how can I read/write the Alfa 147 with Nec?

 

Thanks in advance

Hi, it's difficult to find places where it does not exist.

I'm curious and asking, because all Sellers of Nec Programmer giving info that you can read the following Dashboards:

 

•Citroen Xsara Picasso( NEC MCU in BSI )
•Citroen Xsara 2000-2001 ( NEC MCU in dash )
•Citroen Berlingo 2003 ( NEC MCU in BSI )
•Citroen Saxo ( NEC MCU in BSI )
•Citroen- X-Picasso ( NEC MCU in BSI )
•Peugeot Partner 2003 ( NEC MCU in BSI )
•Peugeot 307 all ( NEC MCU in dash )
•Hyundai- Terrcan JEEP ( NEC MCU in dash )
•Hyundai- KIA ( NEC MCU in dash )
•Hyundai Terracan ( NEC MCU in dash)
•Hyundai Elantra ( NEC MCU in dash)
•Hyundai Sonata ( NEC MCU in dash )
•Honda Civic 2002 ( NEC MCU in dash )
•Honda accord 3.0 (NEC MCU in dash)
•Suzuki Wagon-R ( NEC MCU in dash )
•Renault Clio Sagem Mod2000 ( NEC MCU in dash )
•Renault- Scenic ( NEC MCU in dash )
•Renault Megane Sagem Mod2000 ( NEC MCU in dash )
•Opel Movano Sagem ab Mod2002 ( NEC MCU in dash )
•Opel Agila ( NEC MCU in dash )
•Opel- Corsa ( NEC MCU in dash )
•Alfa 147 ( NEC MCU in dash )
•Chevrolet Caprice-LT2 ( NEC MCU in dash )
•Chevrolet Explore SUV ( NEC MCU in dash )

 

You can see that Alfa 147 exist in the list, but you can not find it in the software.

You can read/write EEPROM from NEC D780828 with ETL NEC and edit it in other calc (NYO4, tschosoft etc.).

[julianstefanov]

Thanks OalikO, will try tomorrow. Hope Alfa Dash got some points to connect the wires on easy.

I have tried today to read the Dash with ETL Nec. Reading is successfull and DUMP is fine, but the KM values on 1st and 2nd line are wrong (around 2,053,193Km). I tried to correct them manualy, then with nyo, then with another calculator and the problem is that I cannot ERASE, MODIFY or WRITE the eeprom. ETL just give me Connection Error at 8x%. It's 8x%, because the eeprom data is starting at address F900 to F9FF. I tried many things to write/modify the eeprom data in the CPU, but with no luck. Is there anything special I must to know? I think that the CPU is write protected or something like that, but can't figure out why and how. Any tips are welcome.

 

Thanks in advance.

Я пробовал сегодня, чтобы прочитать Dash с ETL Nec. Чтение является успешным и DUMP это хорошо, но KM значения на линии 1 и 2 не правы (около 2,053,193 км). Я пытался исправить их вручную, а затем с NYO, то с другим калькулятором и проблема, что я не могу стереть, изменить или записи EEPROM. ETL просто дать мне Ошибка подключения на скорости 8x%. Это 8x%, потому что EEPROM данных, начиная с адреса F900 в F9FF. Я пытался много вещей, чтобы написать / модифицировать EEPROM данных в CPU, но не повезло. Есть ничего особенного я должен знать? Я думаю, что процессор защищен от записи или что-то вроде этого, но не могу понять, почему и как. Любые советы приветствуются.

 

 

Спасибо заранее.

Show dump......

[julianstefanov]

I don't have it here at home. Will show it tomorrow or monday, but I'm sure that the problem is not on the dump. I have tried to erase the eeprom and it gives me "Connection error". Then I read the eeprom (after erase) and it was almost empty but 1st line was not only with FF. It was looking something like that:

 

FF 00 FF FF FF FF 00 FF FF 00 FF FF FF 00 FF 00
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

 

I have original working dump from one of your forum members and I tried to write it, but it gives error too (it is from the same Dashboard model and serial number). Just few addresses cannot be writen/modified or erased. Just on the 1st line.

Anyway, I'll post a dump as soon as I can.

ETL NEC is original? Some clones have problem with power circuit. My programmer write dump when I click "Write" 3 times or more.

If you do it incircuit, mast try it in adapter.

[julianstefanov]

It's a clone. I never had a problems with ETL till now. I tried with external power directly on Dashboard (1,2,3 pins to +12 and 6+7 on gnd) and it was the same problem. Btw it's a good idea to unsolder the cpu and try it not incircuit.

Do you know how much power I must get on ETL power cables 13 and 14? It's 5V for me.

[OalikO]

Yes, its 5 volts for NEC processor. This voltage keep on, when you programming it?

I think, adapter can solve this problem.

[julianstefanov]

Today I tried alot of things and finaly I think the problem is comming from the CPU.

I desolder the cpu from the dash and solder it to adapter. Tried with 3 different quarz generators. Tried with external voltage (not from ETL). All was fail.

I can read the eeprom area normaly. When I try to erase, it gives me error connection at 50%. After fail erase the eeprom area is almost erased, but there're few addresses where data still exist and cannot be erased. And also that data (unerasable) is only on 1st row (line) where the KM info must be stored. When I try to write some data, it fails at 85-86%. All is writen fine except the 1st line and few addresses on the 2nd line.

 

So finaly I heard from a guy, that these NEC cpus got a problem when more than 300,000+ modifications are made on the same address, that address stop working or just fail. So basicaly that can be true, because I have a problem only on the 1st line where the KM values are stored. They was modified by the car alot of times (probably more than 300,000) and now they're broken. Sounds crazy and unbelivable, but...

 

Thanks for the tips OalikO!

 

Tomorrow I'm going to get a new dash for the guy with the Alfa.
