1. Frist of all, write down coding number from original ECU (if you still can connect to it) that was already in the car. Then read flash memory from it. 2. Read eeprom from donor (used) ECU. After that disable immo in it and correct checksums in eeprom (I disabled it using IMMOFF17 tool). Disable the immobilizer in the ECM, that proves the ECM is active.

If a new (or different ECU) is installed in the vehicle, the immobilizer will prevent the car from running and will cause the symbol to flash. To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to validate the digit and resume, repeat the operation until you have entered the entire code.
