This is the 2004 model 9-3.
The engine was ordered when the coolant was hot and the ECU was ordered.
Order used ECUs with the same part number from eBAY
We prepared with OBDLINK SX USB.
Trionic 8 (main) succeeded in downloading existing ECU information.
After that, when the newly purchased ECU is mounted, the radiator fan starts to spin.
After installing the new ECU, press FLASH ECU and it shows failed to get security access and operation failed.
Do not attempt to initialize a used ECU.
Seek help from here.
Is this ECU bad?
Why do radiator fans work?
Can I initialize the ECU?
ECU DATE READ , DOWNLOAD, OK
FAIL..... NEW ECU..
