GODIAG Full-Protocol OBD2 Jumper Adapter

The GODIAG Full Protocol OBD2 Jumper is a versatile adapter designed to connect automotive control modules — including ECU, Immobilizer, ABS, Airbag, and Instrument Cluster units — for diagnostics and programming tasks. It enables OBD2-based ECU programming and is compatible with tools such as MMPS, FGTECH, KESSV2, BYSHUT, DISPROG, and more.

GODIAG Full Protocol OBD2 Jumper Functions

• Supports DC power supply connection for bench programming.
• Features a dedicated banana head super-programming connection port with built-in safety protection for power supply.
• Independent GND4 and GND5 terminals to meet the requirements of specialized ECU programming procedures.
• Includes a Boot GND4 clip, compatible with programming equipment such as MPPS, FGTECH, and KESSV2.
• GND4 / GND5 short-circuit switch included for ECUs that require short-circuit mode during programming.
  • ⚠️ Note: The GND4-5 switch is normally pressed (active/lit). When independent GND4 and GND5 connections are required for specific ECUs, release the switch to separate them.
• Ignition analog switch included, with 1 large and 2 small dedicated ignition cables.
• Supports full standard OBD2 protocol connectivity including dual K-line, dual CAN-line, 3 large and 2 small power plugs, and 4 large and 4 small GND connections.
• Equipped with built-in CAN protocol communication resistance.

What is the Analog Ignition Switch?

The analog ignition switch simulates the vehicle's ignition function on the bench. When the ING ignition switch is pressed, the ING12V line outputs 12V — mimicking the ignition-on state. This is particularly useful because certain programming devices prompt the technician to turn the ignition on or off at specific points during the ECU reading or programming process, and the analog switch allows this to be done conveniently without a physical vehicle ignition system.
