The GoDiag GT105 II combined with the GT107 is a set designed for connecting and programming ECU (Engine Control Unit) and TCU (Transmission Control Unit) modules on a workbench. The system functions as a breakout box and data-Adapter, providing stable power and a communication interface for tasks such as diagnostics, reading and writing data, and cloning modules. The GT105 II is equipped with a digital display showing the current voltage and LED indicators for the status of communication protocols.
This combination is specifically developed for technicians working on control units outside the vehicle. The GT105 II provides the basic connectivity and power supply for various ECUs, while the GT107 is a specialized Adapter for direct access to DSG transmission control units. The GT107 features a switch for an automatic and manual mode, ensuring compatibility with various software, including PCMflash. The set supports a range of TCUs, such as the DQ200, DQ250, and DL501.
Application and functionality:
The set is used for performing diagnostic and programming tasks on control units on the workbench.
- Bench programming of ECU and TCU: Enables connecting control units outside the vehicle for data cloning, repair, and programming.
- DSG data-Adapter: The GT107 offers specific connections and protocols for reading and writing data on various DSG TCU types.
- Stable power supply: Provides a controlled 12V power supply to the connected module, with a real-time voltage display on the GT105 II screen.
- Communication interface: Supports communication via CAN-bus and K-Line protocols, with LED indicators for connection status.
- Diagnostic breakout box: The GT105 II can also be used in a vehicle as an OBD2 breakout box to monitor and check communication lines.
- Compatibility modes: The switch on the GT107 toggles between an automatic mode (for software like PCMflash) and a manual mode for controlling ignition when using other programming tools.
