Description:

 

GODIAG GT100 is a latest testing platform for OBD-II protocol communication detection and ECU maintenance / diagnosis / programming / coding. 

 

It can convert the car OBD2 interface into 16 pin for signal detection and electrical level conversion. It is 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. 

 

Functions and Operation Instructions:

 

1. By connecting the vehicle and diagnostic tool via OBD-II, GODIAG GT100's LED will indicate whether the OBD-II diagnostic interface has a good communication with the car.

 

2. Monitor the voltage of vehicle OBD-II interface and display it in real time. If it is less than 11V, please stop the diagnosis and programming to avoid vehicle start failure/data loss/module lockdown.

 

Connection:

 

1. OBD-II 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

Connects GODIAG GT100 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 OBD-II 16pin interface to tell you whether the OBD-II interface connection is good or not, which is convenient for the test of OBD-II interface voltage waveform.

 

4. Convert OBD-I Diagnostic Interface To Standard OBD2

Use the connector to convert the OBD-I interface into OBD-II 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. Extension Cables:

The space of the diagnostic interface location is too narrow to connect to the diagnostic tool, or the user found 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.

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.

*Do not turn on the ignition switch, do not 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. The dedicated adapter will be released (It will help GT100 to connect to the special ECU module.)
