Description
GODIAG GT100 AUTO TOOLS OBD II Break Out Box ECU Connector
It can convert the car OBD2 interface into 16 pin for signal detection and electrical level conversion. Able to connect the single modules or multiple
modules of the vehicle. It can be connected with any diagnostic tool to tell whether the car communication is good or not. It can also supply power to
the car when you change the battery to avoid the vehicle control module data being lost, automatically locked, the key remote control fails and the fault light turns on.
GODIAG GT100 function and operation guide
– 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. OBDII Protocol Detector & communication detection
1). Connect GODIAG GT100 to the OBDII diagnostic port of the car.
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.)
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 OBD2Use 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.
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.
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.
