Lets say Jose wants to run a test plan for the adaptive xenon lights... He would page forward after doing the short test, go into function selection at the bottom left, then going through service functions and finding lights would get you to anything ouy could set/calibrate, going through complete vehicle could give you more options as well. Find the link that looks to suit what you want to test, highlight it by clicking on it (and any other sub functions that might pull up) then hit the test plan button on bottom left. That brings you to the test plan screen with the test plan you selected and you run through it like any other test plan.
