Try the control module functions button on the right bottom of the page after the short test is done. In there select DME from the list, then see if there is a link in the middle window for component activation. If so then it is in there. Otherwise you gotta go through function selection, complete vehicle, DME, test plan. Then go in through there to expert mode then component activation.
