Product Introduction:
GODIAG GT100 PLUS GPT is a testing platform for OBDII protocol communication detection and ECU maintenance / diagnosis / programming / coding. GT100 PLUS has a voltage and current display which is convenient for maintenance engineers to judge the current working status of ECU.
It can convert the car OBD2 interface into 16 pin for signal detection. It can be connected to the single modules or multiple modules of the vehicle. It can also be connected with any diagnostic tool to tell whether the car communication is good or not.
It supports the 24v to 12v voltage conversion, DOIP-ENET communication and GPT to read and write ECU data.
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.
The product uses CANH and CANL shielded twisted cables, which can resist electromagnetic interference and make communication more stable.

2. Check OBDII diagnostic interface Communication Status and Display Voltage
By connecting the vehicle and diagnostic tool via OBDII, Godiag GT100 PLUS GPT's LED will indicate whether the OBDII diagnostic interface has a good communication with the car. It monitors the voltage of vehicle's OBDII interface and display it in real time. If it is less than 11V, please stop the diagnosis and programming to avoid data loss/ module locked/ the vehicle being unable to start. It supports OBD2 BENCH full protocols.

3. Support DOIP-ENET Diagnostics
Support DOIP-ENET communication
Support diagnostic programming and coding for BMW Benz, Volkswagen, Audi and other vehicles that support DOIP protocol. [no software is provided.]
Can be used for diagnostic programming and coding of Land Rover, VOLVO, and Geely vehicles that support DOIP communication. [no software is provided.]
4. 24V to 12V Voltage Conversion
Convert the 24v voltage of the diagnostic interface of heavy trucks, light trucks, pickups, etc. into 12v voltage that can be used by diagnostic equipment.
5.) Used to check whether the diagnostic / programming / coding tool can send communication signals.
6.) ECU connection: single module connection
GODIAG GT100 PLUS GPT, connected to a single ECU module, is convenient for a user to do the single-module diagnosis and programming.
7.) GT100 PLUS GPT 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 PLUS GPT 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 PLUS GPT+ 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.
8.) GT100 PLUS GPT 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 PLUS GPT can only display K- Line Pwm Vpw+ KWP 2000 protocol. GT100 PLUS GPT will display CANBUS K-Line Pwm Vpw+ KWP 2000 protocol communication.
9.) 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.]
10.)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]
11.) 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 PLUS GPT 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.]
12.) The OBD2 cable of GT100 PLUS GPT 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 PLUS GPT 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]
13.) For old OBD1 vehicles or special diagnostic port, please connect GT100 PLUS GPT through the banana plug and DB25 jumper. The OBD1 diagnostic port or special diagnostic port can be transferred to the standard OBD2 diagnostic port.
14.) GT100 PLUS GPT will convert the OBD1 port of special truck to the standard OBD2 diagnostic port according to the protocol.
15.) Work with CAS1/CAS2 Mech-Key Test Platform
16.) Work with CAS2 CAS3 SER Semi Smart Test Platform
16.) Work with CAS2 CAS3 SER Semi Smart Test Platform
17.) For BMW-CAS4/CAS4+Programming Test Platform, it’s used to test whether the programmed key works with CAS4 normally
