GODIAG - GT100+ New Generation Auto Tools OBD II Break Out Box ECU Connector

GODIAG - GT100+ New Generation Auto Tools OBD II Breakout Box ECU Connector

The GODIAG GT100+ New Generation AUTO TOOLS OBD II Breakout Box ECU Connector features an electronic current display. The GT100+ serves as a state-of-the-art testing platform for OBDII protocol communication detection, ECU maintenance, diagnostics, programming, and coding. It can forcefully activate the instrument and anti-theft system by short-circuiting when all keys are lost. The device includes a voltage and current display, aiding maintenance engineers in assessing the current working status of the ECU. It converts the car’s OBD2 interface into a 16-pin for signal detection and electrical level conversion, connecting single or multiple vehicle modules. It works with any diagnostic tool to check car communication and can also supply power during battery changes to prevent data loss, automatic locking, key remote control failure, and fault light activation.

What is the difference between the GODIAG GT100+ and the GT100?

The GT100+ includes all the features of the GODIAG GT100 with additional enhancements. The GT100+ features a current display on the main unit, allowing users to easily see the current status of the ECU by connecting it via the Banana interface or the DB25 cable, making the work more efficient. The GODIAG GT100+ also supports non-standard CAN protocols.

GODIAG GT100+ Functions Overview:

- When connected to a vehicle and a diagnostic tool via OBDII, the GT100+'s LED indicator shows if there is good communication between the OBDII diagnostic interface and the car.
- It monitors the voltage of the vehicle's OBDII interface and displays it in real time. If the voltage drops below 11V, it is recommended to stop the diagnosis and programming to prevent issues like the vehicle being unable to start, data loss, or module lock.

1) Used to verify if the diagnostic, programming, or coding tool can transmit communication signals

2) ECU connection: single module connection
Connecting the GODIAG GT100+ to a single ECU module allows users to perform single-module diagnosis and programming conveniently.

3) GT100+ key programming for VW, Porsche, Mitsubishi, etc., when all keys are lost - activate the instrument or immobilizer module

To program keys for VW 4th and 5th generation vehicles (e.g., new A6L, Touareg, A4, Q5, A7) after all keys are lost, use the GT100+ to short-circuit banana connector PIN 16 to PIN 1 to light up the dashboard. Then, use the key programmer tool to connect with the female adapter of GT100+ for data collection. Note that for some vehicles like the A6L and Q7, the dashboard may not light up, but data can still be collected.

For replacing the engine ECU of Toyota or programming Toyota keys when all keys are lost, short-circuit PIN 13 to PIN 4.

To program Mitsubishi keys or set OBDII when all remote keys are lost, short-circuit PIN 1 to PIN 4.

To program Porsche Cayenne keys when all keys or remote keys are lost, short-circuit PIN 3 to PIN 7.

4) Voltage and Current Display Function

When connecting the ECU module on the bench using the banana connector or DB25 dedicated ECU interface, the GODIAG GT100+ will display the voltage and current values. This allows the user to see the current status of the ECU intuitively. If there is no current display or the displayed current does not match the engineer's expectations, the user can immediately check for wiring errors. If the wiring is correct, it can be concluded that the ECU may be faulty, eliminating the need for diagnostic communication and allowing for direct ECU repair.

If the display shows excessive current, it can also indicate a wiring error or a faulty ECU.

5) The GT100+ displays CANBUS, K-Line, PWM, VPW+, and KWP 2000 protocol communication 

Pins 1, 9, 3, 11, 12, 13, and 8 on the GT100+ (corresponding to the yellow banana connector on the device) can display non-standard OBD2 protocol interfaces such as CANBUS or K-Line communication. In contrast, the GT100 only displays K-Line, PWM, VPW+, and KWP 2000 protocols.

6) Quickly communicate with a single ECU on the bench by connecting it to the ECU diagnostic or programming tool

This allows engineers or technicians to complete the job on the bench, avoiding the risk of data loss in other modules when testing directly on the vehicle.

7) Connecting Multiple Vehicle ECU Modules

This function is designed to help engineers and technicians who need to connect multiple ECUs during module programming, such as when programming keys by connecting to several ECU modules.

8) Battery Backup Power Supply - Uninterrupted Power Supply Connection Mode

In cases where certain vehicles experience antitheft remote control data loss or failure when the battery is disconnected, the auxiliary power supply provided by GT100+ ensures a continuous power supply to the vehicle. This feature enables the vehicle's ECU to remain powered during battery replacement, preventing disruptions in power supply.

9) The OBD2 cable of GT100+ extends up to 1.4 meters, addressing issues where the diagnostic tool cable is too short or the vehicle's diagnostic port is narrow for connection

First, connect GT100+, then turn on the power switch to view the voltage on the screen, which indicates the normalcy of the vehicle's power supply. This feature helps prevent damage to diagnostic and programming tools that could occur from using modified vehicle OBD2 ports.

10) Convert an OBD1 Diagnostic Port to a Standard OBD2 Diagnostic Port

For older OBD1 vehicles or specialized diagnostic ports, connect GT100+ using the banana plug and DB25 jumper.

11) GT100+ Converts Special Truck's OBD1 Port to Standard OBD2 Diagnostic Port

GT100+ can convert the OBD1 port of a special truck to a standard OBD2 diagnostic port based on the protocol.

12) Used in Conjunction with the BMW CAS4/CAS4+ Programming Test Platform

It is used to test whether the programmed key functions correctly with the CAS4 system.

13) Used with the BMW FEM/BDC Programming Test Platform

14) More connectors and specialized modules are currently in development. Please stay tuned
