Why to choose the GM MDI Tech3 wireless

1) GM MDI is easier to get data from the cars ECU to a computer

2) GM MDI enables you to see the diagnosing something and recording data via MS Excel by exporting it right to a file. So I can send that file to my customers / friends to help troubleshoot even if they do not have a MDI device.

3) GM MDI works more vehicles than Tech2, to be specific newer vehicles after 2010.

4) If you are working with more brands GM, Opel .. You need for the tech new cards, but the MDI can select the .bin for each brand and its a lot faster and easier then switching cards

5) GM MDI diagnostics is an extra fee over and above TIS2WEB all subscription.

  What protocols does the GM MDI support?

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

Beginning with the 2008 model year vehicles, Pass-Thru will be the only programming method available. (Remote will continue to be available for previous vehicles.)


The GM MDI is initially being introduced with Pass-Thru programming capabilities only. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and will support all vehicles into the future.
