Automotive OBDII Protocol Communication Detection Systems Power Probe Godiag GT100 Plus OBD II Breakout Testing Box
Product Description
The GODIAG GT100+ is the latest OBDII protocol communication testing and ECU maintenance/ diagnosis/ programming/ coding test platform. In the event of a lost key, the instrument and anti-theft system can be forcibly activated via a short circuit. It features voltage and current displays, allowing repair engineers to easily determine the current operating status of the ECU. It can connect to any diagnostic tool to determine if vehicle communication is normal. During battery replacement, it can also power the vehicle, preventing issues such as data loss in the vehicle control module, automatic locking, remote key failure, and malfunction indicator lamps.
GT100+ VS GT100:
- GT100+ includes all the functions of the GODIAG GT100.
- GT100+ adds a current display function to the main unit. You can connect the ECU module via a banana plug or DB25 cable to visually view the current status of the ECU, greatly simplifying your work.
- GT100+ also supports non-standard CAN protocols.
GT100+ Function Introductions & Operation Guide
- After connecting the vehicle and diagnostic tools via the OBDII interface, the Godiag GT100+'s LED indicators will show whether communication between the OBDII diagnostic interface and the vehicle is normal.
- Monitors and displays the voltage of the vehicle's OBDII interface in real time. If the voltage is below 11V, immediately stop diagnostics and programming to avoid vehicle startup failure/data loss/module lockout.

1. OBDII Protocol Detector & Communication Detection:
- Connect GODIAG GT100+ to the OBDII diagnostic port of the car.
- When the device displays the voltage, turn on the power switch of GODIAG GT100+.
- 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 twinkle 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.
- 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.)
- The Godiag GT100+ can be powered by connecting to the OBDII diagnostic interface of car, or by an AC power adapter.
- 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:
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 finds 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:
- 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.
- Then replace the brand-new battery B with the used battery in the car, which will ensure that the car has full 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 (help GT100+ connect to the special ECU module)
9. GT100+ can be used for programming & activating the instrument panel or anti-theft module in Volkswagen, Porsche, Mitsubishi, and other models with lost keys:
- For Volkswagen fourth/fifth generation models with lost keys (e.g., new A6L, Touareg, A4, Q5, A7), use the GT100+ to short-circuit pins 16 and 1 of the banana plug to illuminate the instrument panel. Then, use a key programming tool connected to the GT100+'s female connector to collect data. The instrument panel may not illuminate on some models, but data can still be collected, such as the A6L and Q7.
- For Toyota models, if you need to replace the engine ECU or program a Toyota model with lost keys using other key programming tools, you need to short-circuit pins 13 and 4.
- For Mitsubishi models, if you need to program a lost key or set the OBDII system, short-circuit pins 1 and 4.
- For Porsche Cayenne, to program all lost keys or all lost remote keys, short PIN3-PIN7.
10. GT100+ will convert the OBD1 port of the special truck to the standard OBD2 diagnostic port according to the protocol.
