Immobilizer Emulator Circuit Module for Renault EDC15C3 DCU3R MSA15 SIRIUS32 FENIX5 ECU's

For cars where the ECU requires an Immobilizer Code Stored in memory.

Applicable To: All Renault models, fitted with single-data-wire coded immobilisers. From Approx. 1994 until the introduction of CAN (2001 to 2003, depending
on exact model).

Please Read:
Many Renault ECU's can be decoded using a RENAULT RESET TOOL (sold separately) or by entering a security code. After this, in most cases you can start engine, but some ECU's cannot operate without an immobilizer (immo) code stored in their memory.

For these ECU's you can use this Immobiliser Code Emulator!

Example ECU's:
Diesel EDC15C3, DCU3R and MSA15, petrol SIRIUS32 (except for those for 1.4L engine) and FENIX5 for 2.0L 16V engine require a working unlocked (with good key) immobilizer unit or Renault immobilizer emulator.


Use together with a RENAULT ECU DECODER for a complete kit.

All Renault immobilisers of this type share the same features:
The engine ECU won’t run the engine until it receives a coded message (a ‘unique’ number) from the immobilizer. The ‘unique’ part means that every immobiliser is different, and so swapping immobilisers won’t help get a car running.

The immobiliser may be a stand alone unit, or it may be built in to a larger control unit.

Once the ecu has been decoded, (using a separate ECU decoder), the emulator should be fitted as shown in the pictures, this can be done directly to the ecu or along the immobilizer wiring loom.
After connecting the emulator cut the immobiliser line from the immobiliser unit as shown in the pictures.

Fitting Instructions:
  1. Ensure that the ecu has been decoded. This can be done with a separate Renault ECU Decoder.
  2. Connect the module to the cars wiring harness: Red wire to ignition feed, Black wire to earth and Yellow wire to the immobilizer data wire.
  3. Cut the wire to the immobiliser, so that the module is connected directly to the engine ECU, and the immobiliser is out of the circuit.
  4. Turn ignition back on, the car should now start.
