GODIAG GT100 OBDII Protocol Detector OBD2 Break Out Box ECU ConnectorGODIAG GT100 is a brand new ECU connector and protocol communication testing tool. It will greatly help a user to connect the ECU module separately for diagnosis, programming and coding. Also it will tell whether the diagnostic & programming tool can normally send out communication signal.Highlights to get GODIAG GT100:1.GODIAG GT100 is a latest testing platform for OBDII protocol communication detection and ECU maintenance, diagnosis, programming & coding.2. It can convert the car OBD2 interface into 6 pin for signal detection and electrical level conversion.3.Able to connect the single modules or multiple modules of the vehicle.4.Connect with any diagnostic tool to tell whether the car communication is good or not.5.Supply power to the car when you change the battery to avoid the vehicle control module data being lost, automatically locked, key remote control fails or the fault light turns on.6.One Year Warranty.7.Can work together with Xhorse vvdi2, Autel Scanner, Launch Scanner, Foxwell Scanner, Vident Scanner etc, will make your operation much easier.8. for BMW CAS4 Test Platform function will be coming soon, and also will develop the connection cable for Benz and for Chrysler, please wait.9. GODIAG is our brand, we can provide good price and technical support for distributors worldwide.GODIAG GT100 function and operation guide- By connecting the vehicle and diagnostic tool via OBDII, Godiag GT100's LED will indicate whether the OBDII diagnostic interface has a good communication with the car.- Monitor the voltage of vehicle OBDII interface and display it in real time. If it is less than 11V, please stop the diagnosis and programming to avoid the vehicle being unable to start/data loss/module locked.1. Tell whether the diagnostic & programming tool can send out communication signal.After connecting the diagnostic & programming tool to the OBD2 port of GT100, select the car model and function to be performed. Then you will see on GT100 the protocol indicator light will turn on or flash (because the diagnostic & programming tool will send out the communication signal), if the indicator won't turn on, it indicates that the diagnostic & programming tool has a incorrect connection or the machine is damaged.2. Display the status during communication:After connecting GT100 to the OBD2 port of the vehicle, turn on the "Power" switch, then you will see the current vehicle battery voltage displayed on the device. Then to connect the diagnostic & programming tool which will communicate with the vehicle and the corresponding protocol indicator light will turn on or flash on the GT100. It is very helpful for the user to determine what protocol the vehicle module.3. Quickly communicate with a single ECU on bench by connecting with the ECU diagnostic / programming tool. [Which allow the engineers or technicians to complete the job in the office, also keep away the risk of data loss in other modules when directly testing on the vehicle.:4. Allow connect multiple car ECU modules. [Which will greatly help the engineers & technicians who need to connect multiple ECUs when programming a module, for example, key programming is supposed to connect multiple ECU modules.]5. When you replace the battery of the vehicle, GT100 will assist in power supply [After the battery is removed, some cars will be malfunction or lose the immobilizer remote data. If the engineers or technicians connect the battery to GT100 then to the OBD2 port of vehicle before replacing the battery, the ECU will be in an electric state].1). Prepare battery A to supply power by connecting to No. 16 / 4 / 5 holes of Godiag GT100 & to the OBD2 diagnostic interface of the car.Notice:*Turn on the power switch of Godiag GT100.*Don't turn on the ignition switch, don't start the car.2). Then replace the brand-new battery B with the used battery in the car, which will ensure that the car has fully power to prevent data loss and audio lock-up or the malfunction due to lack of power to the ECU control module.6. The OBD2 cable of GT100 is as long as 1.2 meters, which will solve the problem that the diagnostic tool cable is not long enough or the vehicle diagnostic port is too narrow to connect. Please connect GT100 first, turn on the power switch and you will see the voltage on the screen which can tell whether the power supply of the vehicle is normal. [Which keep away the risk of burning out the diagnostic & programming tool due to the modified vehicle OBD2 port]7. After plugging the banana plug to the colored jumper cable, connect GT100 to the OBD1 diagnostic port of old car / special car, and meanwhile with the OBD 2-in-1 extension cable connected to the diagnostic & programming tool, the vehicle will be diagnosed or programmed perfectly. Because GT100 will convert the OBD1 port or the special vehicle diagnostic port to the
