GM MDI Communication Module with TiS SPS Subscription (Kellie OBDING)

Description:

GM MDI  (Multiple Diagnostic Interface) for wireless ECU reprogramming utilizing J2534.  Hardware kit only.

The GM MDI is  initially being introduced with Pass-Thruprogramming capabilities only. It can  be used to perform

Pass-Thru  programming on all vehicles built since 1993 and willsupport all vehicles into  the future.The GM MDI will

be required to  perform diagnostics onselected NAO vehicles for model year 2009. Diagnostic  soft-ware is scheduled to

be released  for the GM MDI during thefourth quarter of 2008.

When  diagnostics are introduced, the MDI will also get a remote data record  capability. This permits recording data

duringa 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 compliantwith SAE Recommended  Practice J2534. The GM SPS

is com-pliant  with SAE Recommended Practice J2534, and the GMMDI is compliant with the  portions of SAE J2534 that

areapplicable  for GM vehicles.

The Future of  the 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.

Introduction of  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:

A GM MDI
B J1962 Diagnostic  connector
C USB cable
D Ethernet cable
E AC adapter/power  supply
Wireless interface
AAA batteries
Owner manual
Operating  software for the MDI will be 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.

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 Tech2:
– 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 will be 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 toconnect 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 the  dealership’s wireless network.

How Will the GM MDI be  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.
 

Note: Requires software subscription to GM  SPS (Service Programming System), which must be purchased separately via the  ACDelco Tech Connect website
