NORRIE,

it doesn't matter; once you reset the FSS if the car needs A it will show only one wrench if it needs B it will show two wrenches. You should not need Service B this early on you will probably need it at around 15k (or like me 18k miles) or when your dual wrench comes on. There is no individual reset for service A or B there is just one main reset; it is a overall master reset and the system will then tell you which one it needs either A or B. What you need is probably service A.
