GODIAG GT100 is the newest AUTO OBD II 16PIN Protocol Break Out Box ECU Connector. This post will share related product info and the guide of how to use it.
GODIAG GT100 OBDII Protocol Detector Overview:
GODIAG GT100 can make automotive diagnostic OBD port switch to 16PIN and be used to switch signal level conversion. It can not only connect modules individually or multiple vehicle modules. But also be connected to any diagnostic device to determine whether the car is communicating properly. The battery can also be replaced to provide power for the car to prevent data loss of the vehicle control module, automatic lock, remote control of the key failure, failure lights on.
Godiag GT100 OBDII Protocol Detector functions:
-OBDII Protocol Detector
– ECU connection
– Compatible with lots of devices
– Convert OBD1 diagnostic interface to the standard OBD2 diagnostic
-Multi-ECU connection mode
–The cable can be extended.
– Power the car when changing the battery
–Optional dedicated adapter

How to use Godiag GT100 OBDII Detector?
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
-The user finds that the diagnostic cable is not long enough during maintenance.
Solution: The extension cables 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 1. Turn on the power switch of Godiag GT100. 2. 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.
- The dedicated adapter will be released (help GT100 connect to the special ECU module)
