Connect GT100 with ThinkCar Pro via OBD 2-in-1 extension cable.
Plug the power adapter to GT100, turn on power switch of GT100. Then the ECU power and ignition will switch as well. Look, the protocol light on GT100 is on, which means the device can communicate normally with ECU.

Tech tip: why should connect to GT100 first?
The OBD2 cable of GT100 is as long as 1.2 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.]
