Renault ECU Decoder
Note: This product is used together with Renault Immo Emulator.
Universal decoding tool for Renault fuel injection ECU
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
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.
Systems this tool was tested with:
SAGEM SAFIR (55pin)
SAGEM SAFIR2 (35pin)
BOSCH MOTRONIC MP7.0
MAGNETI MARELLI IAW 06R
BOSCH MSA15.5 (DTI)
BOSCH EDC15C3 (DCI)
LUCAS DCU3R (1.9D)
Coded fuel cut-off valve (1.9D DDS)
Decoding of engine control units manufactured in range of year
1994-1996 is semi-automatic, from year 1996 - fully automated.
Especially this tool can be useful when rubber-filled FENIX5,
SAFIR2 or coded diesel anti-start valve must be decoded. This tool
will decode all listed type 1 and 2 immobilizer systems..
Buying this tool you will be supplied with all required
information: user manual and connection diagrams. Decoding tool is
stand-alone, no PC is required.
The following ECU's will need a valid immo code:
* Some of FENIX5 for LAGUNA/SAFRANE 2.0l 16V
* All of SIRIUS32 except for KANGOO 1.4l 16V - You can attach the
immo emulator on this ECU after decoding
* LUCAS DCU3R, Bosch MSA15.5 and EDC15C3
This means that after the decoding procedure on one of these ECU is
done, you must have the immobilizer system fully operational
(matching key) to start the engine.
Otherwise after decoding the above ECU's you can use a Renault
emulator as found here.
