## Features

- 【𝗟𝗶𝘁 𝗨𝗽 𝗗𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱】Sometimes, we always worry about the lost car keys. Use the GT100 to short-circuit banana plug connector to lit up the dashboard. In addition, you can also connect with some test platform (e.g. : CASA) to pragram keys.
- 【𝗘𝗖𝗨 𝗕𝗲𝗻𝗰𝗵 𝗧𝗼𝗼𝗹】 GT100 allows you to power an ECU on the bench; you can easily do diagnostics, vehicle immobilizer, and key programming, whether it is on the bench with the included power adapter, or in the vehicle with the OBDII port supplied power.
- 【𝟭𝟲 𝗣𝗶𝗻𝘀 𝗗𝗲𝘀𝗶𝗴𝗻 & 𝟭.𝟮𝗺 𝗘𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻 𝗖𝗮𝗯𝗹𝗲】The input jack layout of OBD2 protocol detector fully simulates the 16-pin layout of the OBDII interface,allowing more tests to be performed quickly and intuitively. When the OBD2 scanner communicates with vehicles, all 16 pins of OBDII breakout box can be easily connected. OBD2 breakout box has female connector and male connector with a 1.2m extension cable.
- 【𝗣𝗼𝘄𝗲𝗿 𝘁𝗵𝗲 𝗘𝗖𝗨 】Through GT100+ OBDII Breakout Box before replacing the battery to sustain the power supply to the vehicle, 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.
- 【𝗠𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗘𝗖𝗨 𝗠𝗼𝗱𝘂𝗹𝗲𝘀】The GODIAG GT100 can not only be connected to a single ECU module for single-module diagnosis and programming, but is also capable of connecting multiple ECU control modules at the same time. You can 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.)
- 【𝗖𝗼𝗻𝘃𝗲𝗿𝘁 𝗢𝗕𝗗𝟮 𝗜𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲】It can convert the car OBD2 interface into 16 pin for signal detection and electrical level conversion. Use the connector to convert the OBD1 interface into obd2 interface according to the diagnostic interface communication protocol.
