Guys,

When running diagnostic mode, what does it mean when you select the option "ALL ID". You generally have the option between running "ALL CODES" or just a specific type (IE, ABS) but if you continue to scroll you get an option for "ALL ID." I'm very curious as to what this means. I also can't find a place to decipher what THOSE codes mean.

Thanks,

Joe

 

the ALL ID is an option to show you the ID numbers off all the modules installed in the vehicle. it is sometimes needed when talking to GM Tech assitance at a dealership. You wont decipher them as they are for the factory to identify what software and hardware are in a specific controller in case there is a problem that another newer module with newer harware or software.

 

thanks
