More Info

More than a simple OBD-II breakout box, the GODIAG GT100+ is an OBD-II breakout box designed specifically for off-board module and key programming and features a display readout for both voltage and current draw through the box.

Each OBD-II pin has a 4mm safety banana socket and a colored LED to indicate status display:
- Green on pins 4/5 indicates ground
- Red on pin 16 indicates power
- Blue (flashing) is for communication lines
Test leads and probes with 4mm banana plugs will connect directly into the 4mm safety sockets.

The front panel has 3 switches, a master power switch for the box and two separate 12V ouputs for powering modules through the DB25 jumper cable.

The GT100+ features a unique DB25 jumper cable which allows technicians to connect to and power up one or more modules when performing module diagnostics, programming or immobilzer work. AESwave has customized this cable to include 4mm banana plugs that makes adapting to terminal connections easy, especially when combined with the uTest Advanced Terminal Kit or similar breakout leads. Also, the DB25 jumper cable features 37 colored coded and labeled leads that are grouped together by function to make it easier to find the correct one.

Use the DB25 jumper cable to connect your scan tool’s OBD-II cable to any OBD-I or manufacturer-specific diagnostic port.

Using the included AC adapter, the GODIAG can also be used as an auxiliary power supply and memory saver during battery service or replacement.

• GODIAG GT100+ Breakout Box

When do AKL such as V-W, P-orsche, for Mitsubishi, or when programming the Toyota ECU, it is necessary to activate the instrument or wake up the IMMO module first. Now can operate directly on GT100+ or GT100
GODIAG GT100+ function and operation guide
1.) Used to check whether the diagnostic / programming / coding tool can send communication signals.

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

A. To program VW 4th generation / 5th generation Lost all keys (for example: new A6L Touareg A4 Q5 A7), please use GT100+ to short-circuit banana connector PIN 16----PIN 1 to lit up the dashboard, aft that use the key programmer tool to connect with the female adapter of GT100+ for data collection. Some vehicle dashboards won't be lit up, but data can also be collected, for example: A6L Q7.
B. To replace the engine ECU of Toyota or to use some key programmer to program Toyota when all keys lost, it needs to short-circuit PIN13-PIN4
C. To program Mitsubishi key with all keys lost or to set OBDII when all remote key lost, please short-circuit PIN1-PIN4.
D. To program Porsche Cayenne key with all keys lost or with all remote key lost, please short circuit PIN3-PIN7.

4.) Voltage and Current Value Display function

On bench connect the ECU module by using the banana connector or db25 dedicated ECU interface, and Godiag GT100+ will display the voltage / current value.
The user can intuitively see the current status of the ECU. There is no current display or The actual displayed current is inconsistent with the engineer's expected current, then you can immediately check whether the wiring is wrong, if the wiring is correct, he can judge that the ECU may be broken, so there is no need to perform diagnostic communication and can directly repair the ECU.
If it shows too much current, then you can also determine if the cable is wrongly connected or the ECU is broken.

5.) GT100+ Pin 1, 9, 3, 11 12, 13, 8 [corresponding to the yellow banana connector on the machine], these non-standard obd2 protocol interface may display CAN BUS or K-Line communication protocol. GT100+ can only display K- Line Pwm Vpw+ KWP 2000 protocol. GT100+ will display CANBUS K-Line Pwm Vpw+ KWP 2000 protocol communication.

6.) Quickly communicate with a single ECU on bench by connecting with the ECU diagnostic / programming tool. [Which allow the engineers or technicians to complete the job on bench, also keep away the risk of data loss in other modules when directly testing on the vehicle.]

7.) Multiple vehicle ECU module connecting. [It’s aimed at solving the problem of engineers and technicians who need to connect multiple ECU during programming a module, such as connecting to multiple ECU modules for key programming]

8.) Replace the auxiliary power supply for the battery - uninterruptible power supply connecting mode. [Since there’s failure or missing antitheft remote-control data of some vehicles when the battery is dismantled, the auxiliary power supply aims at supplying power to the vehicle through GT100+ before replacing the battery to sustain the power supply to the vehicle. It guarantees the vehicle ECU is power connected during replacement of the battery.]

9.) The OBD2 cable of GT100+ is as long as 1.4 meters, which will solve the problem that the diagnostic tool cable is not long enough or the vehicle diagnostic port is too narrow to connect. Please connect GT100+ first, turn on the power switch and you will see the voltage on the screen which can tell whether the power supply of the vehicle is normal. [Which keep away the risk of burning out the diagnostic & programming tool due to the modified vehicle OBD2 port]

10.) For old OBD1 vehicles or special diagnostic port, please connect GT100+ through the banana plug and DB25 jumper. The OBD1 diagnostic port or special diagnostic port can be transferred to the standard OBD2 diagnostic port.
11.) GT100+ will convert the OBD1 port of special truck to the standard OBD2 diagnostic port according to the protocol.

12.) For BMW-CAS4/CAS4+Programming Test Platform, it’s used to test whether the programmed key works with CAS4 normally

13.) For BMW FEM/BDC Programming Test Platform
