GODIAG Full Protocol OBD2 Jumper Adapter

This is a full‑protocol OBD2 jumper adapter designed to assist with connecting electronic control units (ECUs) and other vehicle modules through the OBD2 port for diagnostic, programming, and module work. It’s commonly used by technicians for ECU programming, key/immobilizer work, and communicating with airbag/cluster/ABS systems, especially when standard OBD2 connections aren’t sufficient.

 Key Features

• Full OBD2 Protocol Support: Supports multiple communication protocols — including CAN, K‑Line, and others — allowing connection with a wide range of diagnostic and programming tools like MPPS, FGTECH, KESSV2, BYSHUT, DISPROG, etc.

• DC Power Supply Support: Can draw and supply DC power to ECU/programming tools directly from battery or alternate power.

• Independent Grounds and Switchable Pins: Separate grounds for PIN4 and PIN5, with a switch to short or isolate them as needed for certain modules.

• Ignition Analog Switch: Has dedicated ignition power leads to simulate ignition on/off for modules that require it during programming.

• CAN Communication Resistors: Built‑in resistances support proper CAN bus communication.
