OBDSTAR is set to release a powerful new function that enables OBD virginization for Mercedes-Benz FBS3 and FBS4 transmission control modules (TCM). This upgrade will be supported by KeyMaster G3 and DC706, providing locksmiths and automotive technicians with a safer, faster, and non-destructive solution for replacing used Mercedes-Benz TCUs.
With this new feature, technicians can restore a used TCM to factory virgin status via OBD or Bench mode, eliminating the need for risky hardware modifications and greatly improving workshop efficiency.
Supported Functions
The new upgrade will support the following operations:
TCM Virginization
Write VIN
Personalization (Data Transfer)
More functions coming soon...
Supported TCM Types
This solution supports the following Mercedes-Benz transmission control modules:
When replacing a used Mercedes-Benz TCM, the module's immobilizer data must be cleared first. This process, known as virginization, resets the module to its original factory state.
Traditionally, the module must then be installed and programmed through online programming or personalization using the original manufacturer’s tools, which can be both expensive and time-consuming.
Drawbacks of Traditional Open-Cover & Soldering Methods
Currently, most available solutions for FBS4 (VGS4-0-NAG2) TCM units require destructive operations, such as opening the module housing, cutting circuits, or soldering wires to read or write the data.
These traditional methods present several disadvantages:
High risk of module damage during cutting or soldering
Time-consuming operations that reduce workshop productivity
Irreversible damage may occur if any step is performed incorrectly, resulting in significant financial losses
Because of these risks, many technicians consider the process difficult and unsafe.
Advantages of the New OBD Virginization Solution
The upcoming OBDSTAR OBD virginization solution offers a much more convenient and secure alternative.
Key advantages include:
No cutting required
No soldering required
Supports OBD and Bench modes
Non-destructive operation
Reduced risk of module damage
Faster and more efficient workflow
Using KeyMaster G3 or DC706, technicians can first read the original vehicle data, then perform TCM virginization and personalization (data transfer).
Once the process is completed, no additional online programming is required. The module can be installed directly into the vehicle, and the engine can be started immediately.
This solution significantly improves workshop efficiency while eliminating the risks associated with traditional hardware-based operations.
Note
The availability of functions and supported models may vary depending on software updates and device configurations.

In this post, we’ll demonstrate how to perform ECM data read and write operations on the HONDA 38770-MFJ-A02 ECM using OBDSTAR MOTOMASTER. This procedure is suitable for technicians who need to back up, clone, or restore ECU data safely and efficiently.
This guide demonstrates the procedure for reading and writing Transmission Control Module (TCM) data on the ZOTYE 6DCT360 using the OBDSTAR DC706 ECU Tool (also compatible with Keymaster G3).
Ensure your OBDSTAR DC706 device is updated with the latest software version.
Launch the ECU Flasher application and select the Passenger Car > TCM category.
Use the search function (top right) to quickly locate the ZOTYE 6DCT360 model.
2. Guided Instructions & Connection
Tap the Guide section. Carefully review the Warm Reminder, Menu Description, Operation Guide, Connection Methods, and Special Notes.
Tap Pinout and select BENCH mode. Verify that the displayed module matches your TCM's appearance.
Tap Connector Pinout and connect your cables to the TCM accordingly, following the diagram.
3. Reading & Writing Data
After completing the physical connections, tap Start.
The tool will now establish communication with the ECU.
First, create a data backup (READ): Always back up the original data first. You can customize the backup file name. The storage location is shown on the left side of the screen.
Write data (WRITE): Proceed to write the required data file into the module. The file management system allows you to filter files by name, modification time, or size.
Verification: If the data file has not been modified, verification is typically not required.
Completion: Once the process is finished, the operation is complete.
