With a user-friendly interface, this tool is essential for automotive professionals seeking efficiency and reliability in their diagnostic processes. ## Description GODIAG GT100 function and operation guide-Connect the vehicle and the diagnostic tool through OBDII, the LED of Godiag GT100 will indicate whether the communication between the OBDII diagnostic interface and the vehicle is good. -Monitor the voltage of the vehicle's OBDII interface and display it in real time. If it is lower than 11V, please stop the diagnosis and programming so that it cannot start/data loss/module lock.1. OBD2 protocol detector and communication detectionConnect GODIAG GT100 to the OBDII diagnostic port of the car.When the device displays the voltage, turn on the power switch of GODIAG GT100.Then connect to the diagnostic tool. When the tool communicates with the car, the LED indicator of the corresponding protocol will light up or flash. (If the CAN protocol is detected, it has the maximum brightness. After the communication is successful, the corresponding CAN-H and CAN-L will become weak or flicker)2. ECU connection: single module connection GODIAG GT100 connected to a single ECU module is convenient for users to perform single-module diagnosis and programming.Connect the ECU to the color jumper. (If the ECU is CAN protocol, please check if you need to connect a 120 ohm resistor.)The Godiag GT100 can be powered by connecting to the OBDII diagnostic interface of the car or through an AC power adapter.Diagnose and program each ECU by connecting the diagnostic tool or ECU programmer. 3. Banana plug extension connection:Extend the OBD216pin interface of the car to tell you whether the OBDII interface is connected correctly, which is convenient for testing the OBDII interface voltage waveform.4. Convert OBD1 diagnostic interface to standard OBD2According to the diagnostic interface communication protocol, use the connector to convert the OBD1 interface to the obd2 interface.5. Simultaneously connect multiple ECU cont Review: No funciono - Justamente hoy lo recibi buen enbalaje pero al momento de probarlo la pantalla del voltaje no enciende ya realize varias pruebas y sigue sin encender la pantalla de voltaje una pena Review: quality product ## Features - OBDII breakout box and ECU connector: GODIAG GT100 is a type of ECU connector, protocol communication assessment and detection equipment. It is convenient for you to connect the ECU module for diagnosis, programming, coding and other operations separately. - Multiple functions: Includes OBDII protocol detection and protocol communication assessment, voltage indicator, ECU connector, OBD1 diagnostic interface to standard OBD2, multiple ECU connection mode, power supply for the vehicle when changing battery and other functions. - Save Car Data Function: When replace the battery, plug OBD2 breakout box into the car, at the same time connect additional power to the control box, so that ensure the vehicle control module data being lost, automatically locked, the key remote control fails and the fault light turns on. - Monitor the OBD Interface: You can monitor the OBD interface voltage and ground, showed low voltage in real time, Display diagnostic stitching error. If it is less than 11V, please stop the diagnosis and programming to avoid the vehicle being unable to start/data loss/module locked. - OBDII protocol detection function: When the tool is communicating with the car, the LED indicator of corresponding protocol will light up or flash. If the CAN protocol is detected, it will have the maximum brightness. When the communication is successful, the corresponding CAN-H and CAN-L will dim or twinkling weakly. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08HS2HVDP | | Best Sellers Rank | #103,924 in Automotive ( See Top 100 in Automotive ) #438 in Automotive OBD-II Engine System Diagnostic Tools | | Brand | GODIAG | | Brand Name | GODIAG | | Customer Reviews | 4.2 out of 5 stars 91 Reviews | | Manufacturer | GODIAG | | Operating System | Windows 10 | | Operating system | Windows 10 | | Power Source | Corded Electric | | Power source | Corded Electric | | Screen Size | 5 Inches | | Screen size | 5 Inches | | UPC | 889327046287 | | Unit Count | 1 Count | ## Product Details - **Brand:** GODIAG - **Operating system:** Windows 10 - **Power source:** Corded Electric - **Screen size:** 5 Inches - **UPC:** 889327046287 ## Images ![GODIAG OBD2 Breakout Box OBDII Protocol Detector ECU Connector Diagnostic Data Link Connector(DLC) ECU Maintenance Diagnosis Programming Coding - Image 1](https://m.media-amazon.com/images/I/71PmNz-e40L.jpg) ![GODIAG OBD2 Breakout Box OBDII Protocol Detector ECU Connector Diagnostic Data Link Connector(DLC) ECU Maintenance Diagnosis Programming Coding - Image 2](https://m.media-amazon.com/images/I/51Y6Payx-wL.jpg) ![GODIAG OBD2 Breakout Box OBDII Protocol Detector ECU Connector Diagnostic Data Link Connector(DLC) ECU Maintenance Diagnosis Programming Coding - Image 3](https://m.media-amazon.com/images/I/41q11ooAu4L.jpg) ![GODIAG OBD2 Breakout Box OBDII Protocol Detector ECU Connector Diagnostic Data Link Connector(DLC) ECU Maintenance Diagnosis Programming Coding - Image 4](https://m.media-amazon.com/images/I/513FwA3UckL.jpg) ![GODIAG OBD2 Breakout Box OBDII Protocol Detector ECU Connector Diagnostic Data Link Connector(DLC) ECU Maintenance Diagnosis Programming Coding - Image 5](https://m.media-amazon.com/images/I/513yRsRlTCL.jpg) ## Questions & Answers **Q: I can programthe ecu and code?
