How to slove the problem for GM MDI “no communication with the vehicle” and Solutions About GM MDI Scan tool for some problems

Tech2Win is a Windows application which can be loaded onto a service PC or laptop via TIS2Web. It provides much convenience to the operation of GM MDI diagnostic scanner. But improper operation may leads to system errors. Here provides the MDI Tech2Win no communication error and solution.


After install Tech2Win software application, connect the GM MDI interface with Opel Zafira-B 2008 to reset ABS light. The software program was allowed to access to Chassis control module, but soon the Tech2Win system display error message: “no communication with the vehicle”.


Possible reason:
The right bottom (0) icon indicates that MDI Tech2Win software has not need well installed and activated.

Re-install and activate the GM MDI GlobalTIS MDI Tech2Win GDS2 software again.
If there is (1) icon displayed on the right bottom of the Tech2Win program, the software has been successfully installed and there is good communication between vehicle and GM MDI scan tool.




Sometimes when you use the GM MDI, you will meet some problems and here we will share the reasons and the solutions of those problems. In many conditions, when there occurs some troubles when you are using the MDI, you should first reboot the MDI software and do the Self Test.




If you meet this problem, it indicates that there is an internal problem in the MDI, you need to connect the MDI to a PC by using the USB and do the software recovery procedure.


This condition indicates that during power on, there has detected a problem. And the solution is to power down the MDI and verify that it has the same problem after you power up again, then connect the MDI to a PC by using the USB and do the software recovery process.


Normally speaking, Once the external power is applied,the MDI should power up. If the MDI does not turn on, the first thing you need to do is to check the wall plug or power cable connections. Then try to supply power to the MDI from the two different power sources, the vehicle DLC connector and the AC 12-volt Adapter.

To solve this problem, you need to check and make sure that the cables are all attached to the MDI securely and the connector pins are all clean. If you are going to connect to the vehicle DLC connector, try to power from the AC 12-volt Adapter. And if you are going to connect to the AC 12-volt Adapter, you should try to power from the vehicle DLC connector.


Actually, after it is disconnected form the vehicle, the MDI should stay on for a factory set time unless you press the power button. If the MDI turns off immediately once you disconnected it from the vehicle, you should power up the MDI and verify that it has the same problem when the power is removed, then replace the batteries and make sure they are properly installed. After these operation, if it still fails to be off correctly, your MDI may be damaged.
