How to Clone a Dodge Ignition Switch (WIN Module) using Xhorse Multi Prog step by step?

 

Replacing or cloning a Dodge ignition switch, also known as a Wireless Ignition Node (WIN) module, can be a cost-effective solution when the original module fails. In this article, we’ll walk through the process of cloning a Dodge WIN module using MultiProg, a tool designed for reading and writing microcontroller data. This guide will help you understand how to clone the module, ensuring that the vehicle’s VIN, key information, and other critical data are preserved.

 

 

Understanding the WIN Module

The WIN module is a critical component in Dodge vehicles, responsible for managing the ignition system and immobilizer functions. When the module fails, the vehicle may not start, and replacing it with a new one can be expensive. Cloning the original module allows you to transfer all the necessary data to a donor module, saving both time and money.

In this example, we’re working with a 2010 Dodge Journey. The original WIN module has a Renesas 70F processor, which stores the vehicle’s VIN, key information, and other immobilizer data. By cloning this data to a donor module, we can ensure that the vehicle recognizes the new module as if it were the original.

 

 

Tools and Equipment Required

To perform this procedure, you’ll need:

• Xhorse Multi Prog: A tool for reading and writing microcontroller data.
• MCU Adapter: Used to connect the WIN module to MultiProg.
• Soldering Iron and Solder: For making connections to the WIN module’s processor.
• Donor WIN Module: A replacement module with the same part number as the original.
• Laptop: To run the MultiProg software and save the data.

 

 

Step 1: Preparing the Original WIN Module

1. Open the Original Module: Carefully open the original WIN module to access the processor. In this case, the module had already failed, so it was safe to disassemble.
2. Identify the Pinouts: Refer to the diagram provided by MultiProg to identify the correct pins for VCC, ground, RXD, and other connections.
3. Solder the Connections: Scratch the contact points on the processor to ensure a good connection, then solder the wires from the MCU adapter to the appropriate pins. Start with VCC and ground, followed by the data pins (RXD, TXD, etc.).
4. Connect to MultiProg: Once the connections are secure, connect the MCU adapter to MultiProg and your laptop.

 

 

 

 

Step 2: Reading Data from the Original Module

1. Read the D Flash: Using Multi Prog, start by reading the D Flash memory. This contains the vehicle’s VIN and key information. Save this data as “original” for reference.
2. Read the P Flash: Next, read the P Flash memory, which contains additional software and configuration data. Save this data as well.
3. Verify the Data: Ensure that the data has been read successfully and that there are no errors or corruptions. This step is crucial to ensure a successful clone.

 

 

 

Step 3: Preparing the Donor WIN Module

1. Open the Donor Module: Carefully open the donor WIN module to access its processor. Ensure that the part number matches the original module.
2. Solder the Connections: Repeat the soldering process on the donor module, connecting the MCU adapter to the appropriate pins.
3. Verify Connections: Before proceeding, double-check that all connections are secure and that there are no shorts.

Step 4: Writing Data to the Donor Module

1. Write the D Flash: Using MultiProg, write the D Flash data from the original module to the donor module. This transfers the VIN and key information.
2. Write the P Flash: Next, write the P Flash data to the donor module. This ensures that the software and configuration are identical to the original.
3. Verify the Write: After writing the data, re-read the donor module’s memory to ensure that the data has been written correctly and matches the original.

Step 5: Finalizing the Clone

1. Reassemble the Donor Module: Once the data has been successfully written, carefully reassemble the donor WIN module.
2. Install the Donor Module: Install the cloned WIN module in the vehicle.
3. Test the Vehicle: Start the vehicle to ensure that the new module is recognized and that the keys work correctly. The vehicle should start without any issues, and the immobilizer light should turn off.

 

Important Notes and Tips

• Part Number Matching: Ensure that the donor WIN module has the same part number as the original. Using a mismatched module can cause compatibility issues.
• Data Backup: Always save the original data before writing to the donor module. This allows you to compare the data and ensure that the clone is accurate.
• Soldering Skills: Proper soldering is crucial for a successful clone. If you’re not confident in your soldering skills, consider seeking professional help.

 

By following the steps outlined above, you can successfully clone the module, preserving the vehicle’s VIN, key information, and immobilizer data. This approach is a cost-effective alternative to purchasing a new module, especially for older vehicles.
