GODIAG GT105 ECU IMMO Prog OBD II Breakout Box ECU Connector

Key Highlights of the GODIAG GT105

• Safe and Easy IMMO Operation: Eliminates the need to disassemble ECUs for Ford, Mitsubishi, and Volkswagen, reducing the risk of short-circuits.
• Communication Diagnostic Assistance: When a diagnostic tool reports no communication, connect the GT105 to test signal transmission between the vehicle and device. If communication is established with the GT105, the issue may lie with the original diagnostic tool or its compatibility.

Product Description

The GODIAG ECU IMMO Prog AD GT105 is a specialized adapter designed for automotive technicians, anti-theft programming specialists, and ECU engineers. It allows safe and reliable access to vehicle systems without direct ECU disassembly. The unit can draw power from a car battery and convert it into a stable DC12V output, making it suitable for powering tablets, standalone diagnostic tools, or programming equipment in field operations.

Equipped with signal indicators for PWM+ (PIN2), CANH (PIN6), CANL (PIN14), and K-line (PIN7), the GT105 visually displays active data communication through flashing lights. This enables users to verify real-time communication status between the vehicle and connected diagnostic or programming devices.

Ideal for outdoor diagnostics and repairs, the GT105 supports powered operation from a vehicle battery, delivering consistent 12V power for programming, charging, or running independent diagnostic hardware. It features dedicated OBD2 ground pins—PIN4 (body GND) and PIN5 (signal GND)—enabling specialized module programming. When used with an OBD2 full-protocol ECU programming cable, it also allows bench programming by connecting directly to the ECU for precise power adjustments.

Product Functions

• IMMO AD Power Adapter: For Ford models post-2016 with all smart keys lost, the GT105 works with VVDI, OBDSTAR, Autel, and other anti-theft tools to perform key programming.
• All-Key-lost Programming: Capable of waking up instrument clusters or anti-theft ECUs. Supports VAG 4th and 5th generation immobilizers, Toyota ECU synchronization, Mitsubishi all-key-lost matching, remote key programming, and Porsche Cayenne anti-theft key learning.
• Communication Status Monitoring: VPW, CANH, CANL, and K-Line indicator lights allow instant assessment of communication between the vehicle and diagnostic/programming device. Users can determine if the connected tool is sending signals correctly.
• Mobile 12V Power Supply: Draws 12V from the car battery to power programming tools such as Xhorse Key Tool Plus Pad, VVDI Prog, CGDI Prog, and Autel IM608 during outdoor operations—ideal for reading BMW, BENZ, and other brand ECU data for on-site fault diagnosis and repair.
• Power for Key Cutters: Supplies 12V power to external devices like key cutting machines.
• Standard OBD2 Full-Protocol Programming Cable Support: Compatible with MPPS, FGTech, Kess v2, and similar tools for ECU reading, writing, cloning, and tuning. (Note: OBD2 full protocol ECU programming cable sold separately)
