Diagnostic device adapter - GODIAG GT105

Godiag GT105 IMMO ECU OBD Diagnostic Tool Adapter

The Godiag ECU IMMO Prog AD GT105 is a specialist connection adapter designed for technicians working in diagnostics, anti-theft systems and ECU programming. The device converts power from the car battery into a stable 12V DC source, allowing it to be used both to power diagnostic equipment and to charge selected tablets.

The adapter is equipped with LEDs indicating communication for the PWM (PIN2), CANH (PIN6), CANL (PIN14) and K-line (PIN7) protocols. The flashing of the relevant indicators signals active data transmission, allowing you to quickly assess the integrity of the communication and check whether the diagnostic device is connecting correctly to the system.

The GT105 is also suitable for mobile use — it can draw power directly from the vehicle’s battery and convert it to 12V, which can be used for ECU programming or to power devices outside the vehicle, e.g. in a workshop setting.

The device offers independent OBD2 outputs: PIN4 (chassis ground) and PIN5 (signal ground), which is particularly useful for advanced programming of certain modules. Additionally, pins 4 and 5 can be switched between short-circuit and open-circuit modes. Thanks to the complete OBD2 protocol wiring, it is also possible to connect the ECU outside the vehicle and adjust its programming conditions.

Key features:

•    Full support for ECU connections for programming and power management.
•   Independent OBD2 pins (PIN4 and PIN5) for specialist applications.
•   Ability to switch the state of PIN4 and PIN5 (short circuit / open circuit).
•   Standard, independent PIN4 and PIN5 terminals.
•   Socket made of pure copper, resistant to repeated plugging and unplugging.
•   Battery terminals protected by a corrosion-resistant coating (salt spray test, 0.5 mm thick).
•   Battery power cable: 2-core 0.75 mm², compatible with DC 5.5×2.5 and 5.5×2.1 plugs.
•   DC connector fitted with a resettable 7A fuse.
•   Dedicated DC laboratory power interface.

The GT105 is compatible with VVDI equipment (OBDSTAR, AUTEL) and other devices
