Description
GM MDI (Multiple Diagnostic Interface)
for wireless ECU reprogramming utilizing J***4. Hardware kit
only.
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 ***3 and will support all vehicles into
the future. The GM MDI will be required to perform diagnostics on
selected NAO vehicles for model year ***9. Diagnostic soft-ware is
scheduled to be released for the GM MDI during the fourth quarter
of ***8.
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 J***4. The GM SPSis com-pliant with SAE
Recommended Practice J***4, and the GMMDI is compliant with the
portions of SAE J***4 thatareapplicable for GM
vehicles.
The Future of the Tech 2
The Tech 2 remains an essential tool through at least the ***0
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 from previous model
years. Remote programming with the Tech 2 will continue to be
supported for use on all ***7 and previous vehicles. Additional
information will be supplied in future.
Note: Requires software subscription to GM SPS (Service Programming
System), which must be purchased separately via
the ACDelco Tech Connect
website
