55252659 MJD8F3.BD – VIRGIN PLUG&PLAY | ECU ENGINE CONTROLLER Fiat Ducato 2.3 JTD Euro 5
Original ECU ENGINE CONTROLLER 55252659 in MJD8F3.BD version prepared in VIRGIN (PLUG&PLAY) condition. The unit has been professionally cleaned, reset and tested for CAN communication, power supply and correctness of Flash and EEPROM memory. After installation in the vehicle, the controller automatically adapts to the immobilizer – without manual coding and without the need for online programming.
The VIRGIN version means that the controller is ready for first adaptation in the vehicle. After connecting to the vehicle installation, automatic synchronization with the Body Computer and the immobilizer system takes place. An ideal solution in case of damage to the original unit (flooding, no communication, short circuit, memory error).
