Renault ECU decoder From the year 1994 most Renault cars are equipped with engine immobilizer system and it makes replacement of injection computer more complicated. There is no problem if replacement ECU is bought from Renault service dealer - it is sold with no immobilizer code stored, but replacing damaged computer with used one is impossible because of mismatch of unlocking codes.

Decoding tool has several modes of operation and deals with all known petrol and diesel injection systems, introduced in range of year 1994-2001 without intervention in to the ECU (diesel coded anti-start valve as well). After decoding process is completed, control unit became de coded - as it was bought from dealer. ECU must be taken out from the car and connected to the decoding tool according to user manual.
