Saab Trionic 8 how to change VIN and IMMO code?

**soxten** · 9th April, 2014, 07:20 AM

Need to replace a ECU on a Saab 9-3 2004 2,0T but have some problem...
I can read flash by FGtech V53 on canbus.
I can open bin-file in T8suite.
I can see VIN and immobilizer code BUT I can`t change it... (gray marked in program)

I don`t have Tech2 and TIS for coding in car, only ECU on bench.

.bin file are hex coded so I can`t see and change info...

Did try to connect OP-Com China and choose Vectra and Trionic ECU but can`t change anything.
Even try`d Saab special at bottom of year in Op-Com but don`t work...

Is it possible to fix this?

Plz someone?
Need more info.

Is vin and immo code stored in flash or i somd of the 2 mcu as is on the pcb?

I have desolder flash and read it by Wellon programmer.
Flash is Xor decrypted.

I did clone flash to a ECU from 2003 (not same partnumber!...) and car starts and run perfect

After a test drive Check engien lamp is lightning in dash and I get "wrong in ecu" and this is from wrong partnumber on ECU.

SO..... If you clone flash you can swap ecu!

I still need to find a program to change Immo code + VIN in the Xor crypted flash file.
T8suit cant change this.

You can reset this easy m8 with opcom no need to open the ECU...
Bat after you most sincronize ECU with tech2 in car..

Lycka till!

Opcom china ask for pin to reset, not possible!
Pin Opel 4 digit and Saab 10-15 digits....

4 digit opel code you can se in t8 suite from ecu dump and reset

**soxten** · 22nd April, 2014, 08:41 AM

But in T8suit giv both digit and number.
In opcom you can only type digits.

Or?

**maybach_** · 22nd April, 2014, 11:35 AM

No no no in opcom you can type digit and number also if you do not se the code in t8 suite so yo can take out from VIN

Hi, for full good working clone T8 You must program ECU by BDM first, and after that by CAN with the same file.

**soxten** · 12th July, 2014, 09:34 AM

Why this problem?
Where is all info stored?
All other ecu we can clone (exept edc17 as we do immo of on)

Have someone try to copy mcu in ecu?
We may(?) need to clone flash and mcu

T8 has 2 MCU, but all info is stored only in external flash (29BL802CB). I wrote above how to make correct clone of that ECU. Last I did it about one week ago. Tested and works for sure.
