GODIAG GT100 Auto Tool OBDII Connector

Highlights of 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.
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. Work together with Xhorse VVDI2, Autel devices, Launch, Foxwell etc.
8. Work with BMW CAS4 Test Platform and BMW FEM/BDC Test Platform

Notice: Please choose in Version according to the voltage of your local place.

GODIAG GT100 Description:

GODIAG 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.

GODIAG GT100 Features:

1. OBDII Protocol Detector & Communication Detection

1). Connect GODIAG GT100 to the OBDII diagnostic port of the car.

2). When the device displays the voltage, turn on the power switch of GODIAG GT100.

3). Then connect to the diagnostic tool, 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)

2. ECU connection: single module connection

GODIAG GT100, connected to a single ECU module, is convenient for a user to do the single-module diagnosis and programming.

1). Connect the ECU with the color jumpers. (If the ECU is CAN protocol, please check whether you will need to connect a 120 ohm resistor.)

2). The Godiag GT100 can be powered by connecting to the OBDII diagnostic interface of car, or by an AC power adapter.

3). To diagnose and program for a single ECU by connecting the diagnostic tool or ECU programmer.

3. Banana plug extension connection:
Extend the car's OBDII 16pin interface to tell you whether the OBDII interface connection is good or not, which is convenient for the test of OBDII interface voltage waveform.

4. Convert OBD1 diagnostic interface to the standard OBD2
Use the connector to convert the OBD1 interface into obd2 interface according to the diagnostic interface communication protocol.

5. Connect multiple ECU control modules at the same time, which is convenient for the professional engineers to detect and maintain.

6. When to use the extension cables:
The space of the diagnostic interface location is too narrow to connect to the diagnostic tool, or the user find that the diagnostic cable is not long enough during maintenance. It can be extended by 1.2 meters.

7. Able to power the car when replacing the used battery.
GODIAG GT100

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.

8. GT100 will convert the OBD1 port of special truck to the standard OBD2 diagnostic port according to the protocol.

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.
