Please review the following statement carefully:
The statement can help you quickly learn how to use GODIAG products. Please abide by the
relevant local laws. If you use the GODIAG equipment illegally, the user shall bear all the risks, and
the company will not assume any responsibility.
For the safety of yourself and others, and to avoid damage to equipment and vehicles, please read
the safety precautions carefully. Due to the variety of procedures, tools, parts and techniques used
in vehicle maintenance, the variability in how personnel operate, and the variety of diagnostic
programming applications, this manual cannot predict and provide safety recommendations for
every situation.
It is the responsibility of the automotive service technician to get a thorough understanding of the
system being tested and to use appropriate service methods and testing procedures reasonably.
When testing, you must use appropriate operating methods to avoid threats to yourself and others
in the work area, as well as to avoid damage to the equipment being used or the vehicle being
tested.
Before using the equipment, please refer to and follow the safety information and applicable test
procedures provided by the vehicle or equipment manufacturer. Please use the equipment in
accordance with the instructions in this manual, and read, understand and follow all safety
information and instructions in the manual.
Note for reading and writing ECU data:
1. Connect the DSG gearbox in the studio to read and write data, be sure to use a stable and reliable
power supply (12V 4A-5A). Note: Insufficient power supply can cause ECU damage or data loss.
2. If the car battery is connected as the power supply, it must be ensured that the voltage is at 12V
and there is enough power in the vehicle battery (to support power for at least 30 minutes). It is
recommended that you can start the car first and then connect the device. Note: Insufficient power
supply can cause ECU damage or data loss.
3. Connect the power supply of Godiag ECU IMMO Prog AD first, and check that the IMMO function
switch on it must be up (the switch is off)
4. View the DSG gearbox wiring definition and connect the DSG gearbox. Then connect GT107 to
Godiag ECU IMMO Prog AD.
5. The “Auto” mode and “Manual” mode selection of the GT107 start switch is selected
according to how you want to operate (the switch is popped up to be “Auto”, and the switch is
pressed down to be “Manual” . The “Manual” mode is used for PCMFlash software diagnosis.
It is recommended to use the “Auto” mode for reading and writing data. Other software uses
“Manual” mode.)
6. Since some ECU operations require special attention, please read the following content carefully.
GODIAG GT107 is a DSG gearbox connection adapter. DSG Gearbox maintenance engineers can
clone, diagnose and repair DSG Gearbox ECU and can also read, write and adjust data or power for
DSG Gearbox ECU via PCMFlash, PCMTuner, and Kessv2, etc.
This adapter has automatic and manual selection for PCMFlash software. For data reading and
writing, you can choose “Auto”, and for diagnosis you can choose ”Manual”. For ECU models DQ200,
DQ250, DQ500 you can also choose “Manual”. For other software like kessv2, please press down
the 120 ohm resistor switch.
Moreover, with the car battery power, the adapter can directly read and write DSG Gearbox data
and you can clearly check the communication status during the data reading and writing process.

Connection Steps:
1. Connect Godiag GT107 to the gearbox ECU like VAG, DQ250, DQ200, VL381, VL300, DQ500,
DL501, for Renault DC0/DC4 Gen2 and Honda LUK UDCT.
2. Connect GT105 and connect 12V 2A DC power supply. (GT105 IMMO function keys must be
up.)
3. The GODIAG GT107 analog ignition switch is in “Auto” mode if it is not pressed, and in
“Manual” mode if pressed down(note: please select the corresponding mode in the software to
read data)
4. Connect PCMFlash, PCMTuner J2534passthru.
5. Perform data reading and writing operations.

Steps:
1. Connect Godiag GT107 to gearbox ECU DQ250, DQ200, DQ500.
2. Connect the Godiag ECU IMMO Prog AD with the vehicle battery or 12v 3A power supply. (The
Godiag ECU IMMO Prog AD’s IMMO button must be up.)
3. Connect kessv2 device, and press down the GT107 switch and it will be in “Manual” ignition
mode.
4. Press down the 120 ohm resistor switch.
5. Connect the computer and open the software to read and write data.
Work BOOT:
use a direct connection to the connector of the control UNIT, the switching power
supply is carried out either manually (recommended) or by using the scheme of automatic power
control, GODIAG GT107 DSG gearbox data adapter (same PowerBox or converted from KESS). In
case of manual control, the entrance to the boot mode may not happen on the first attempt.
Read DQ500: only when connected directly!
NOTE:
the power supply must be switched manually, while only the ignition must be switched on
or off (pin 15), the second contact must be connected constantly.
Operation in BSL with VL300 / V30: requires drilling a single hole in the minimum diameter cap in
order to insert a probe into it. The probe is connected to the GODIAG GT107 DSG Gearbox Data
Adapter BOOT 1k ohm GND line(included in the GT107 host). It is mandatory to connect to-line
and it is highly recommended to use auto power to quickly “feel” the pin on the board. The
photos below show the drilling location and the point on the board where the probe should go.
