Technical issue to precode pcf7947 (Renault ClioIII)

[gibor]

Hi, first at all sorry for my awful English, Im Italian and I speack only Italian, but for the rest of people try to write trough google translate.


The question is: The hitag of pcf7947 have 8pg
first “0” is id not changeable from customer
“1” is hex byte of ISK LO
“2” skip two first, other is hex of ISK HI
“3” skip one, other is password
“4” to “7” probabilty code stored can clip for indentifier a car


section remote have another 4 row
“4” RSK LO
“5” RSK HI
“6” RCF (remote configuration... one two or tree button?)
“7” SYNC (sincronization of rolling code?)


At end I want to set precode pcf7947 for my clioIII
read from uch the dump (or seem another mode is a can clip)
extract from file the isk code encrypted
calculate the real isk with RENAULT PIN EXTRACTOR 2
and the first four byte of real isk is ISK HI, and other two byte is ISK LO?
These bytes to put from position “1 and 2” of hitag?
The password on row “3” what is?


On section remote what put on RSK row?
If my key have two button what code put to row “6”
and the row “7” is stored from can clip at procedure to store new key?


I remember the pcf7947 is writable one shot. After store the ISK the chip entry on mode irreversibility to lock mode. On other word the procedure is necessary to store in reverse (first remote, password and isk).


Thank for anyone to clarify this my issue!

Pre-code is OK , key is OK too , use other tool to program it !
for this car , use Renolink if you don't have PIN code OR ddt4all if you have extract PIN code !
FVDI=120€
Renolink crack + OBDlink SX = 70€
ELM 327 ( PIC25K80 ) + DDT4ALL = 5€

Thank at all for reply!


At time dont'have extracted pin code. Desouldering memory is operation dangerous and time to find another mode.


The elm327 is categorical version ( PIC25K80 )?
I have version pl2303 or pic18f2585, and ddt4all have tried to connect at car, but not find what menu is for key programming...


other issue: this tool is money waste for programming key on Renault?

[gibor]

Thank you!
One step at time: have shipped the elm327 suggested (create new account from aliexpress) total amount 8,39€...
Two step: after receive the eprom from web, test the reader, and if work then umount read and remount the original from UCH.
Three step: put on this topic this HEX request...OK!
After one mount receive the elm shipped, and view the choice to make new key from my clio.


At least good work!


Ps. the driver on Linux not are problem. Kernel working without any difficulty.

 USB Serial support registered for pl2303
 pl2303 3-2:1.0: pl2303 converter detected
 usb 3-2: pl2303 converter now attached to ttyUSB0
 usbcore: registered new interface driver pl2303
 pl2303: Prolific PL2303 USB to serial adaptor driver

Other issue: from ddt4all there is the choice of UCH.
My clioIII have marked on UCH type BCM L2 CR1 V12.10
from this menu what is the just choice?

Regards.

[TERMINATOR1000]

The choice of the UCH is determined by the Scan function, no problem with that!


Ask to read the reserved frame is the problem to solve now, if someone would connect his fnr 4 in 1 and give us USB data in


using this software (https://mega.nz/#!HMMn1JSQ!hMiRXC8Yk-_CJ6Qv3JylnEHYVICANXdoy9EeFPqU4yo) to sniff the query. ..


No need for car just chose "read PIN code 3 clio" on fnr 4 in 1, after select "COM port number" in Free Serial Port Monitor 3.31

[gibor]

I'm sorry, I don't understand , but not have fnr4-1.
From my elm327 the first ask ddt4all not detect anything. Prompt to choice post over.
The new interface make to get just model...

[gibor]

The first three step are solved. Have read and extract the pincode.
