SCENIC II ECU VIRGINIZE / REPLACE

[aporebski13]

Hello, I have a problem with my Scenic. It is 2.0 petrol automatic https://carinfo.kiev.ua/cars/vin/renault/vin_check?su=rlev07n2xrga

It had small fire and Injection ECU was damaged ( S3000). Unfortunate EPROM was damaged.

I had bought cheap, a S3000 ECU wit almost the same numbers - apart S/N. , but from 1.6 manual.

Is it possible to virginize it and program actual VIN and all EPROM memory for 2.0 automatic with the use of DDT4ALL ?

I have also good clone of Renault CAN Clip with reprog - but it cannot change VIN therefore automatic configuration is not possible ( There is a function that in theory and probably will configure ECU by its VIN, and maybe update eprom )

Is there a way to obtain EPROM dump or somebody knows a place on the internet where I could find dump or virginized dump for this car - I can desolder and program the eprom, I just newer played with cars electronics ;)

I did that, just virginize the eeprom by filling it with $FF. Then connect it to the car and power it up. It will automatically pair with the car and set up parameters from hardware connections. You'll need to finish air intake and other learning.

Thanks for reply.. problem is that I dont have original EPROM dump, and new ECU is from different engine and power (1.6l < 2.0) so the dump would be different ... I wonder If I change the VIN , CAN CLIP would do the rest?

on MHH Auto i had read that to virginize I need to put FF FF FF .. from 00 to B2 - but stil don`t have original dump

Vin programming is not mandatory to start the car, about the engine power issue, you may need to reprogram the injection map with clip after.

[aporebski13]

Can you give a hint how to : "reprogram the injection map with clip after." ?

After Virginizing ECU do I need aditionaly program an old VIN number??

As I understand from what they wrote change the chassis number with RenoLink, if you have a Renault CAN Clip (reprog) and a (token) that will do automatic promotion (token), you can pull your own car software from the renault pool

Unfortunately not, I had a Clip clone that worked 3 days before it passes away... I tried the partial EEPROM clear, for me it was the opposite, the ECU was programmed for an auto gearbox and my car car has manual shift. It didn't work, only full clear worked. You better start with a 2.0-16V engine map programmed ECU.

Unfortunately I do not have Renolink, only some USB ELM which work with DDT4ALL and good clone of Renault CLIP. I think it would be possible to reprogram it with PIN Extractor (as token).. maybe,

Firstyl need to virginize ECU - so either open it and program 95160 SPI, or is it possible wit DDT4ALL ? I means virginize , and then changing VIN in ECU for the actual of the chassis.

[BarektE]

Token has to be inserted in CLIP. It is impossible to do without Token with CLIP.

[aporebski13]

Yes, reprog uses Renault.net with paid token and some operations can be done wit CD (reprog) and crack calculator for tokens called PIN EXTRACTOR as I understand. I will be fighting with it in weekend. But still don`t know if I could program new VIN with DDT4ALL ?

[BarektE]

Reset the chassis number of the ECU you purchased with Renolink, you will go to the Renault authorized service, the authorized service will automatically write the ECU information of your car from the Renault database.

[aporebski13]

:) to old car for such hustle and cost. Do not have Renolink....

I wonder if It will work ? https://github.com/cedricp/ddt4all/issues/450#issuecomment-686321721

[BarektE]

A personal encrypted USB flash provided by Renault is used to connect to the Renault database. It is only given to authorized service personnel. It's called (Token)

I wonder if It will work ? #450 (comment)

This will work, you need to calculate CRC, though

[BarektE]

You can write a new Chassis number with ddt4all or ECU.

[cedricp]

S3000 command is here :

[cedricp]

Forgot I did that too :+1:

[cedricp]

Not sure it will work, though, the data type is "hexadecimal", and shouldn't be typed as string.

[aporebski13]

So the correct CRC for VF1JM0U0A32625939

is 374D ? many thanks :)

[aporebski13]

VF1JM0U0A32625939 to hex ? -> 5646314a4d305530413332363235393339 so the command will be

3B815646314a4d305530413332363235393339

[cedricp]

yep, CRC looks correct, but it needs to be appended to the command :

3B815646314a4d305530413332363235393339374D

[aporebski13]

Ok, I will give it a try :) maybe it will work.

[aporebski13]

OK, virginization was easy with simple programmer CH341a ( small modification regarding Vcc to 5V).

Unfortunately I couldn`t change VIN with DDT4All, there were always an error: 0:37:16.478;7E0;3E;7F3E80;NR: Service Not Supported In Active Diagnostic Mode

tried different sessions but it didn`t change. But I was able to program new VIN with the Renault Can Clip - unfortunately no auto adaptation / configuration and programming were available. Funny thing configuration Injection ECU S3000 was correct ( auto transmission etc) therefore probably after virginization EC|U read some config from rest of the CAN network .

[aporebski13]

I tried also new ELM327 i bought but it don`t work with DD4ALL https://viaken.pl/pl/polski-elm327-v4-interfejs-vscan-stn2120-usb.html It says it should work but there is communication error: PermissionError: [Error 13] Permission denied
