New GM MDI2 WiFi GDS2 Multiple Diagnostic tool
11/07/2019
The new GM MDI2 can be used only in the Pass-Thru method. This means you can use it as your programming tool, while your Tech 2/CANDY remains available for diagnostics and other duties.
The GM MDI2 is initially being introduced with Pass-Thru programming capabilities only. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and will support all vehicles into the future.
The GM MDI2 will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the GM MDI2 during the fourth quarter of 2008. 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 MDI2 is compliant with the portions of SAE J2534 that are applicable for GM vehicles.
