GODIAG Full Protocol OBD2 Jumper for ECU Programming, Connects ECU

GODIAG Full Protocol OBD2 Jumper is a dedicated tool designed to bridge your programming equipment and the vehicle’s ECU for reliable ECU programming. Built to support the full OBD2 protocol, it handles dual K-line and CAN-line communication and provides a comprehensive set of power and ground connections to accommodate a wide range of ECUs. Whether you’re updating firmware, performing calibration tasks, or enabling advanced programming modes, this jumper offers a stable, safe connection and clear wiring diagrams to minimize setup time.

Its features include DC power supply support, a safety protection banana head and dedicated connection port power supply, independent GND4 and GND5 to meet the needs of special ECU programming, a boot GND4 clip compatible with programming equipment, and a configurable GND4-GND5 short-circuit switch for ECUs that require shorting during programming. The ignition analog switch, equipped with one large and two small dedicated ignition cables, lets you emulate ignition on/off states as some ECUs require during programming. Note: the GND4-5 switch is normally pressed to light; release the switch if an ECU needs separate connections to GND4 and GND5. The unit also includes CAN protocol resistance and supports standard OBD2 full protocol connections (double K line and double CAN line) with multiple power and ground plugs.

Benefits & Tips

• Streamlines ECU programming by integrating essential connectors (power, ground, ignition, and CAN/K-line interfaces) into a single jumper, reducing wiring errors and setup time.
• Use the GND4-GND5 short-circuit switch for ECUs that require shorting during programming, and toggle to independent GND4/GND5 when an ECU needs separate ground references.
• Leverage the ignition analog switch to accurately reflect ignition states during reading or writing operations, ensuring device prompts and ECU responses align with actual vehicle conditions.
