The Adapter Cable is designed to establish a direct connection with the Transmission Control Unit (TCU) of Mercedes-Benz vehicles equipped with a 7G-Tronic (722.9) automatic transmission. This cable allows the TCU to be connected outside the vehicle, on a workbench, to diagnostic and programming equipment. The cable features a specific TCU connector and a standard 16-pin OBD2 connector for universal compatibility with reading devices.
This cable is specifically intended for tasks such as reading, writing, cloning, or renewing the software on the transmission control unit. By powering and connecting the TCU separately from the vehicle, technicians can perform data recovery and programming tasks in a controlled manner. This is especially applicable during repair or replacement of the TCU, where data from the old module must be transferred to a new one.
Application and functionality:
The Adapter Cable is developed for specialists performing work on the 7G-Tronic TCU.
- Direct TCU connection: Enables a direct communication line between a programming device and the transmission control unit.
- Bench programming: Facilitates working on the TCU outside the vehicle, necessary for tasks such as data cloning, software flashing, and performing repairs.
- External power supply: Equipped with a separate connector to supply the TCU with 12V power from an external source, making it functional on the workbench.
- Standard OBD2 interface: The female 16-pin OBD2 port ensures compatibility with a wide range of diagnostic and programming tools.
Compatible vehicles and Application:
This Adapter Cable is compatible with a wide range of Mercedes-Benz models equipped with the 7G-Tronic (722.9) automatic transmission, including TCU types such as VGS2-NAG2 and VGS3-NAG2.
