For GM we use the MDI module scan tool,which is part of the future of all GM vehicles,along with GDS,which is global diagnostic system which is all laptop based and can only be used with the MDI module which can read data and codes,wright now the only vehicles its used on is 2010 camero,equinox and la cross.the average scan tool will not communicate with these vehicles,pretty soon all GM vehicles will be like this.glad I have all the training for all this!
this is the scan tool people will need.
