The GODIAG GT105 II is an essential specialized interface for automotive locksmiths and ECU technicians. This "Break Out Box" acts as a safe communication bridge between a vehicle's OBD2 port and your diagnostic or programming tools. It is specifically designed to assist with IMMO (Immobilizer) programming, ECU flashing, and key matching by providing a stable power supply and clear signal indicators.

The GT105 II allows you to interact directly with the vehicle's electronic systems without risking damage to the original wiring. It is a vital tool for situations where the vehicle has lost all keys or when an ECU needs to be programmed on a bench.

Core Functions & Capabilities

• OBD2 Signal Monitoring: Features built-in LED indicators for all 16 OBD2 pins, allowing you to instantly see if the communication (CAN-High, CAN-Low, K-Line) and power lines are active.

• Safe Power Supply: Provides a dedicated power connection to ensure your diagnostic tool stays powered on during critical programming, even if the vehicle's battery voltage fluctuates.

• ECU Bench Connection: Includes specialized jumper leads to connect directly to an ECU outside of the vehicle for cloning or repair.
