Up for auction is a NEW in the box GM MDI scan tool/interface kit. It comes complete with all cables, documentation and accessories shown in the pictures. The GM Multiple Diagnostic Interface (MDI) is a compact communication module that manages the transfer of data between a vehicle's onboard ECU network and a PC. The GM MDI offers faster programming speed at a lower cost. Depending on the vehicle architecture, the MDI can be 20%-70% faster than the Tech2. MSRP $2,495, 1000 obo
If you're familiar with the Tech 2, and are curious about the MDI and it's capabilities, please read the following FAQ provided by GM:

What is the GM MDI?

The GM MDI is a compact communication module that manages the transfer of data between a vehicle’s onboard ECU network and a PC.

The EL-47955 MDI is a kit of components:

GM MDI

J1962 Diagnostic connector

USB cable

Ethernet cable

AC adapter/power supply

Wireless interface

AAA batteries

Owner’s manual

Flash files for the MDI are downloaded from the TS2WEB website.

The GM MDI allows the user to perform Pass-Thru programming procedures using software running on a laptop or desktop PC.

Any PC can be used, so long as it meets the PC Hardware Specification located at this link:

Benefits of the GM MDI

The GM MDI offers faster programming speed at a lower cost. Depending on vehicle architecture (protocols/modules), the GM MDI can be 20-70% faster than the Tech 2. This helps alleviate vehicle battery drain problems during programming.

Using the GM MDI for programming also frees up your Tech 2 for diagnostics and other tasks.

No additional PCs are needed. PCs that have been installed under the Multiple PC Initiative (MPI) meet the PC Hardware Specification when using the GM MDI.

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)

For future use -- Global architecture coming in July 2008 for MY 2009 will use a total of 4 GMLAN links. (This is a limited rollout in MY 2009.) Global architecture adds a medium speed bus and an expansion bus. The Tech 2 and CANdi module can run only low and high speed, and won’t work on the 4 GMLAN link system for diagnostics or programming. The MDI will have this capability.

How is the GM MDI Connected?

The GM MDI is connected between the vehicle and the PC using the DLC and cable.

Connection between the GM MDI and the PC can be accomplished several ways.

- using the supplied cable to connect the mini USB port on the GM MDI and the USB port on the PC

- using a standard CAT5 cable to connect the Ethernet port on the GM MDI and the Ethernet port on the PC

- using the WLAN card built into the GM MDI to communicate with the PC through a wireless network

Power connector (AC adapter)

MDI connections -- top

Mini USB connector

Ethernet connector

The GM MDI has an easy to grip, comfortable, rugged enclosure. Rubber end covers offer extra shock resistance.
The GM MDI is powered through the DLC when connected to the vehicle. In addition, it has 4 AAA batteries for backup. The unit can also be powered using the provided AC adapter plugged into any 120V AC electrical outlet. Detachable port covers protect these connectors:

- Mini USB

- Ethernet

- Trigger switch

- Power


How is the GM MDI Used?

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 1993 and will support all vehicles into the future.

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 during the fourth quarter of 2008.

When diagnostics are introduced, the MDI will also get a remote data record capability. This permits recording data during a road test, similar to the Tech 2 Snap Shot function. A trigger switch connector is provided for this purpose.

Regulations require programming procedures to be compliant with SAE Recommended Practice J2534. The GM SPS is compliant with SAE Recommended Practice J2534, and the GM MDI is compliant with the portions of SAE J2534 that are applicable for GM vehicles.
