How to Solve the Problem for GM MDI

There have many situations cant use GM MDI , when you have some troubles to use the tool ,  you should reboot the MDI software and do the Self Test first . Please check the bellowing 4 issues for GM MDI :

1. “MDI DOES NOT PASS 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 or you can contact your local customer support center for help.

 

2. “MDI ERROR LED LIGHTS AFTER POWER ON”

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. Ask your local customer support center is ok.

 

3. “MDI FAILS TO POWER UP”

Normally speaking, Once the external power is applied,the MDI should power up. If the MDI from CnAutotool 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. If your MDI still can’t power up, then you may have a problem with your MDI, you’d better contact with your local support center.

 

4. “MDI TURNS OFF IMMEDIATELY WHEN DISCONNECTED FROM THE VEHICLE”

Actually, after it is disconnected form the vehicle, the automotive scan tool 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.

What protocols does the MDI for GM Support?
For immediate use — At present, vehicles have two buses on the 16 pin connector
(high speed and low speed GMLAN). The GM MDI scan tool communicates using all of the existing GM protocols, the same as the Tech 2:
– UART
– Class 2
– KWP2000
– GMLAN (CAN)

The Future of the GM Tech 2
The Tech 2 remains an essential tool through at least the 2010 model year. The GM MDI will not support past models when its diagnostic capabilities are introduced. And, the Tech2 will continue to be needed to diagnose all vehicles fromprevious model years. Remote programming with the Tech 2 will continue to be supported for use on all 2007 and previous vehicles.Additional information will be supplied in future.

HOW WILL THE MDI BE USED?
The GM MDI will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the GM MDI at CnAutotool.com during the fourth quarter of 2008.
