RENAULT ECU DECODER

MANUAL

1. 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. In most cases even after medium-strength impact it became unusable because of mechanical damage and must be replaced. However from 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 computer with used one is impossible because of mismatch of unlocking codes. And that was why an idea to create universal Renault ECU decoder revealed. Now if you have this tool you can take used injection computer and make it not coded as it was bought from Renault stores. Decoder has several modes of operation and covers 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). 2. SYSTEMS THIS TOOL WAS TESTED WITH:

PETROL DIESEL MAGNETI MARELLI IAW 06R BOSCH MSA15.5 (DTI) BOSCH MOTRONIC MP7.0 BOSCH EDC15C3 (DCI)

4. OPERATION Front view of decoder presented in figure 1.

Figure 1. Front view.

MODE button is used to switch between operation modes. Mode can be changed only before pressing red START button. When decoding is in progress, MODE button becomes not operational. There are 4 operation modes:

MODE “MODE” LED Standard OFF

Advanced 1 ON Advanced 2 Slow blinking

Semi-Auto (TYPE1 immo) Fast blinking All 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. Which mode is to be selected depend on engine immobilizer type and several other factors, described below. Connect ground, battery +12V, MIL lamp and relay (if required). Use any 12V lamp (up to 2W), any relay with 12V coil and 12-14V power supply (over-current protection would be an advantage). Apply +12V IGN, lamp must blink. If lamp goes on and does not blink, ECU is already not coded or there is mistake in connection. Connect decoder box as follows: red wire to ECU’s +12V BAT, black wire to GND, yellow wire to ECU’s +12V IGN (decoder switches +12V on and off by itself) and green wire to ECU’s immobilizer input.

5. IMMOBILIZER SYSTEM OVERVIEW Renault immobilizer systems are divided in to three types – TYPE1, TYPE2 and TYPE3. This tool is able to decode ECUs with TYPE1 and TYPE2 immobilizer. Engine ECU from the TYPE2 system is decoded automatically with this tool; therefore TYPE1 ECU decoding is semiautomatic. It is very easy to find out what type of immobilizer is used with ECU you want to decode: if after ignition-on malfunction indicator lamp (MIL) illuminates for 2 seconds then starts to flash, this is TYPE2 immobilizer system; if after ignition -on malfunction indicator lamp (MIL) flashes immediately, this is TYPE1 immob ilizer system.

5.1 Decoding TYPE1 immobilizer system engine ECU 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. Use PIN CODE TABLE (available on the last chapter of this instruction) to convert this number to security code. For ex.: MIL stopped blinking on 89-th ignition-on: program calculates code 2232. ECU is not decoded after this procedure; you only found out its security code! Count number can be in range 1-255. In worst case when MIL stops to blink on 255-th ignition-on, counting takes about 8 minutes. Put ECU back to car and turn key to ignition-on. Injection fault lamp flashes quickly.

1. Depress and keep depressed accelerator pedal fully – injection fault lamp extinguishes. To enter security code use trip computer button on the end of wiper control stalk. This button is called ADAC button.

2. Press the button the same number of times as the first figure of the code, checking injection fault lamp illumination each time the switch is pressed.

3. Release the accelerator pedal: injection fault lamp flashes. Repeat operations 1, 2 and 3 to enter in succession the three other digits of the code. When the code has been entered the injection fault lamp should be illuminated continuously for 2sec and then must to extinguish. ECU is no longer protected by

immobilizer and is ready to retain new code. If injection fault lamp flashes, the code is incorrect. Switch off the ignition, switch it on again and repeat procedure for entering code. Procedure for code entering can be performed without car as well. Accelerator pedal depressing-releasing emulate using throttle position potentiometer connected to the ECU, button connect between ground wire and immobilizer line (see wiring drawings). 5.2 Decoding TYPE2 immobilizer system engine ECU Decoding process is fully automated. On SIEMENS FENIX5, SIRIUS32 and coded solenoid valve select Standard type of operation (green LED off). Other systems may require Advanced 1 or Advanced 2 mode (especially engine control systems, where ignition-on signal to ECU is passed via fuel pump relay coil, e.g. SAFIR2), but is worth to try Standard mode first. Decoding in Standard mode takes about 1h 50min, in Advanced 1 – almost 4h, in Advanced 2 – more than 5h. In most cases 1h 50min is enough to make ECU not coded. Ignition is switched from off to on by decoding tool; red LED indicates ignition on. After decoding, ignition is switched off and all leds is turned off. After decoding, ECU is not coded and can be used on another car. If immobilizer system is ok (valid key), ECU retains new code from immobilizer control unit after ignition on. Most of decoded ECU can operate without immobilizer code stored (Fenix5, diesel coded solenoid valve, some of SIRIUS32, …), other require immobilizer code to be stored. 6.
