Saab Trionic 8 how to change VIN and IMMO code?

**alclot** · 27th October, 2014, 09:39 AM

Hi soxten. I have a problem to see if you can help me. I have read the bdm and obd with fgtech2. I program first bdm and drive stops communicating by obd. By bdm connect and communicate again but I can not work for obd. You know, if you could recover?
I attached the two files.
Thanks in advance and resgards

1:Read broken ecu by can (fgtech) and save "original.can.bin"

2:swap byte in file and save as "original.bdm.bin"

You have now 2 files!

3: program used ecu by fgtech BDM with "original.bdm.bin"
OR program flash by desolder flash and program with Wellon with file "original.bdm.bin"
(I like to desolder and program on my wellon)

4

rogram used ecu by fgtech can with file "original.can.bin""

Mount in car and start!

Hi
I normaly desolder flash and program by wellon.
I have this problem one time and that was when I have solder flash backwards....

Please write original file back by BDM and then program original file back by obd and then start over agin.

This is normaly easy,
1:read by obd and save as original_OBD.bin from broken ecu
2: change "swap" bytes in original_OBD.bin and save as original_BDM.bin (you see diffrent in start of file ex 00 10 .. .. . to 10 00 .. .. )
4:write original_BDM.bin to flash in used ecu by desolder or BDM
5: write original_OBD.bin by obd in used ecu.

Hello again. The problem is that after programming by bdm, obd stops working. I tested with two ECU and the same situation. Can you think of any solution, or I'll have to desolder memory?
Thanks in advance

Program_ECU_with_techII_will continue to experiment.

Desolder flash!
Always work for me!

OBD not works because probably BDM programming was wrong. Make a test - write ori file by BDM then read it from ECU by BDM. I think readed file will be different than ori file. If I was right I got solution for it.

Hi have find that FGtech V54 is not working 100% on Saab Trionic8, use KESS V2 that program will work.

(Opel Trionic8 is not the same as Saab, You cant read flash over OBD by choosing Saab, I have not find any program to read Opel Trionic8 yet, please help!!)

i have a ecu to clone and are broken can?t read by obd, i can read new ecu with ioterminal an this interface can read only virtual eepron, someone try to clone only this?

Read flash by BDM or desolder and read in a adapter.
Write it back to used ecu.
Swipe byte in file from bdm/desolder and name obdfile.bin
and program that file back by obd kess,fgtech by pinout to trionic8
Done! Work 100%!

?Write it back to used ecu.? desoldeing flash no?

**soxten** · 5th March, 2015, 09:37 AM

You can read flash by BDM or by desolder flash and read in a adapter.
After reading broken ecu then save file as bdm_flash.bin, swip bytes in file and save as "obd_flash.bin"

Program used ecu flash by bdm or by desolder flash with bdm_flash.bin
Then connect it to canbus =normal obd connections lile pinout for trionic8
Program now obd_flash.bin in to ecu.
Mount in car and drive!

ok thx, i try to change flash and loose can comunication with used ecu is normaly?

**soxten** · 5th March, 2015, 03:16 PM

If you move flash 29BL802 from broken to used all is going to work!
But car dont runs perfect and you NEED to program file over OBD (swap byte from flash se start of file "00 10" to "10 00")
And program over obd

No, flash of brocken ecu solder in used ecu, used ecu lost can comunication and need 50 mAmp minus of intensity, i think that flash are broken, i send Flash to a friend for read it.
