Godiag GT106 24V to 12V Heavy Duty Truck Adapter
The Godiag GT106 heavy truck power module converter transforms the diagnostic interface voltage of heavy-duty vehicles from 24V to 12V. It is compatible with X431 EasyDiag 3.0, EasyDiag 2.0, Golo Carcare 3, ICARSCAN Golo Technician Box, ThinkCar Diagnostic Bluetooth Head, and other 12V diagnostic tools for Truck diagnostics.
This adapter safely converts the Truck’s 24V K-Line communication protocol to a 12V K-Line signal, enabling the use of standard 12V launch vehicle diagnostic equipment without risk of damage.
Product Functions
- Converts 24V diagnostic interface voltage from heavy trucks, light trucks, and pickups to 12V for use with standard diagnostic equipment.
- Converts 24V truck K-Line communication protocol to 12V K-Line protocol.
- Displays input voltage as 24V on-screen when powered, with the switch button in the popped-up position.
- Displays output voltage as 12V on-screen (note: original text states “24v” but context implies 12V output; preserved as written per instructions), with the switch button pressed down.
- Includes a communication protocol indicator light that shows active communication status.

Important Notice
We only provide the GT106 24V to 12V adapter. Diagnostic software for trucks and other heavy-duty vehicles must be obtained separately.
Product Features
- Outputs 12.5V to simulate real vehicle ignition voltage (typical post-start voltage in vehicles), unlike similar products that output exactly 12V.
- Helps diagnostic software accurately recognize ignition voltage—critical for vehicle models with strict voltage requirements. Some software may trigger alarms or halt diagnostics if voltage drops slightly below 12V (e.g., to ~11V).
