(This is a limited rollout in MY 2009.) Global architecture adds a medium speed bus and an expansion bus. The GM MDI communicates using all of the existing GM protocols, the same as the Tech 2:įor future use - Global architecture coming in July 2008 for MY 2009 will use a total of 4 GMLAN links. PCs that have been installed under the Multiple PC Initiative (MPI) meet the PC Hardware Specification when using the GM MDI.įor immediate use - At present, vehicles have two buses on the 16 pin connector (high speed and low speed GMLAN). Using the GM MDI for programming also frees up your Tech 2 for diagnostics and other tasks. This helps alleviate vehicle battery drain problems during programming. Depending on vehicle architecture (protocols/modules), the GM MDI can be 20-70% faster than the Tech 2. The GM MDI offers faster programming speed at a lower cost. When software coverage on the GM MDI is fully operational, all diagnostic and reprogramming for GM vehicles globally will be supported with this one piece of hardware at a dealer cost of less than $800.00 USD. Today, the dealer cost to equip a technician to diagnose and reprogram vehicles is $2880 USD (Tech 2 and CANdi). (in Canada, review GM Dealer Infrastructure Standards located on the GM infoNET). TIP: Any PC can be used, so long as it meets the PC Hardware Specification located at this link: The GM MDI allows the user to perform Pass-Thru programming procedures using software running on a laptop or desktop PC. Operating software for the MDI will be downloaded from the TS2WEB website. The GM MDI is a compact communication module that manages the transfer of data between a vehicle’s onboard ECU network and a PC. TIP: Additional tools can be ordered by calling 1.800.GMTools, using prompts 1 or 4. The GM Multiple Diagnostic Interface (MDI) EL-47955 is being shipped to NAO dealers during the second quarter of 2007, one per dealer (fig. I believe this is a move to provide scanner capabilities thru a laptop.
In fact GM has been pushing dealers to support the Multiple PC Initiave and provide at least one laptop per 2 technicians. MDI which is currently available from GM runs using an interface similiar to the one on eBay along with software running on a laptop. High end scanners are expensive because:ġ - Much less limited market than laptopsĢ - Captive market, with few competitors. My snap on Solus pro scanner has more ump and memory and other stuff in it that all of my other laptops and pc have all together.
THAT IS THE REASON A GOOD HIGH END SCANNERS IS IN THE 3-5 GRAND RANGE. It would cost a fortune to write the programs and set up a lap top to even think about getting to anything but obd11. OBD 11 is easy to hook up to but it is the other computer systems and engine specific that is the hard and expensive stuff plus can system on newer cars and trucks.
