What is Renolink V2.10?

Renolink is a USB-based diagnostic cable used with a Windows computer. It works on Renault and Dacia vehicles from approximately 2004 up to newer models. The tool communicates via the OBD2 port in the car and supports CAN, KWP, and ISO protocols.

With Renolink, you can:

• Read and clear fault codes

• Reset airbag ECUs

• Program new keys and remote controls

• Customize dashboards

• Recode or replace various ECU modules

Preparations before installation

For a smooth installation, you will need:

• A Windows computer (Windows 7, 10, or 11 recommended)

• Administrator privileges on the computer

• Access to a USB port

• Temporarily disable your antivirus program during installation (it can otherwise block important files)

Step-by-step: Renolink Installation

1. Install drivers

When you connect the cable for the first time, Windows will ask for drivers. Install them so that the computer can correctly recognize the cable.

2. Install the software

Install the Renolink program (version 2.10). For some versions, you may need .NET Framework 4 installed on your computer.

3. Prepare the interface

1. Open the program folder and run the file IFPREP2.exe as administrator.

2. Select the option 115200 > 1000000 to change the communication speed.

3. Click on “Prepare Interface”. This creates an activation file.

4. Check connection

• Connect the cable to the car's OBD port and the computer via USB.

• Open Device Manager in Windows and verify that the cable has been assigned a COM port.

• Ensure that the settings are:

  • Bits per second: 115200

  • Latency Timer: 1 ms

Using Renolink

Once the installation is complete, you can start the Renolink program and select the vehicle. Then, select which ECU module you want to work with.

Examples of functions:

• Fault code reading and clearing

• Resetting airbag modules

• Programming new keys and remote controls

• Dashboard coding

• ECU adaptation and replacement

Important safety tips

• Always connect a battery charger during programming to avoid voltage drop.

• Always back up ECU data before rewriting anything.

• Never disconnect the cable while programming is in progress.

• Only make advanced changes if you have the knowledge – incorrect settings can cause damage to the vehicle's electronics.

Common problems and solutions

• Antivirus deletes files → Turn it off during installation.

• IFPREP2.exe missing → May have been deleted by antivirus. Reinstall.

• Cable not recognized → Install FTDI drivers and check the COM port.

• Communication problems → Check that the speed has been changed to 1,000,000 baud.
