If lamp goes on and does not blink, ECU is already not coded or there is mistake in connection. Use any 12V lamp (up to 2W), any relay with 12V coil and 12-14V power supply (over-current protection would be an advantage). Connect ground, battery +12V, MIL lamp and relay (if required). Which mode is to be selected depend on engine immobilizer type and several other factors, described below. “MODE” LED OFF ON Slow blinking Fast blinkingĪll you have to do is connect decoder to the ECU you want to decode, according to connection diagram, select desired operation mode and press red START button. There are 4 operation modes: Mode Standard Advanced 1 Advanced 2 Semi-Auto (TYPE1 immo) When decoding is in progress, MODE button becomes not operational. Mode can be changed only before pressing red START button. MODE button is used to switch between operation modes. Operation Front view of decoder presented in figure 1.

Now if you have this tool you can take used injection computer and make it not coded as it was bought from Renault stores. And that was why an idea to create universal Renault ECU decoder revealed.

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. However from year 1994 most Renault cars are equipped with engine immobilizer system and it makes replacement of injection computer more complicated. In most cases even after medium-strength impact it became unusable because of mechanical damage and must be replaced. Introduction Have you ever seen where fuel injection ECU (Electronic Control Unit) on the Renault car is located? Yes, it is located in most vulnerable place in the engine compartment.
