Hello,
I would like to ask you for help with immo synchronization for Toyota GT86 / Subaru BRZ. Original SMART ECU was damaged by mechanics and I am not sure what they did to the car. Anyway I got some backup of damaged SMAT ECU eeprom and original keys. I am able to turn the ignition ON when I touch the engine switch with the keys but can not start the engine because of B1572 (immo). It seems to be caused by steering lock ECU. I also tried different steering lock ecu with no success. It can not be synchronized and unlocked. Even synchronization via Techstream can not be done and also connecting PINs 4/13 CG/TC for 30mins did not solve the issue. Every try of ID registration, Key erasure or key add or smart reset via original Toyota Techstream diagnostics will end up with some FAIL. I read out SMART eeprom from friend car but same result with his dump and keys. Issue is not in the car, I already swapped the ECUs to another car and also connected whole system on my desk. New smart ECU is working fine, when I clone friend eeprom and put the smart ecu to his car, the car will strart. I am lost...
Car have no ID Code box, only SMART and steering lock and ECM are connected within the IMMO system. ECM in GT86/BRZ have no eeprom. (I did not found it). Keys seems to be DST 80bit.
I am attaching eeproms(BINs) from SMART ECU 93c86 16bit litle endian, and Steering lock ECU 93c46 16bit little endian.
Could you help me please?
