Top  Previous  Next

This is special function for using with Universal Decoding Tool for Renault fuel injection ECU also known as Renault Immo Tool. This function available only for using with TYPE-1 immobilizers.

 

 

Select Semi-Auto operation mode (fast green LED blinking). Press START button. After every ignition-on, MIL immediately starts to blink fast. Watch the ECU MIL lamp and count number of ignition-on (start counting from 1). Note number of ignition-on cycles when MIL stops blinking for a while.

 

ECU is not decoded after this procedure, you only found out its security code. In worst case when MIL stops to blink on 254-th ignition-on, counting takes about 8 minutes.
