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.
