CBS stands for "Conditions Based Service": CBS has replaced the SI (oilservice / Inspection) system, becoming standard equipment on many models in 2005 and later. People often confuse the Oilservice and Inspection lights with the CBS system, however it is important to note that they are entirely different. Our tools will not reset the CBS maintenance lights. If you have a 2005 or later (or a 745 of any year) it is important to be able to tell them apart. The most notable difference between the CBS system and the SI (oilservice and inspection) system is the oil change reminder (CBS will say "oil") (SI will say "oilservice"). Other visible differences exist to help you tell CBS from SI: such as a more detailed listing of the maintenance that needs to be done: Where the SI system will simply say "Inspection", the CBS system will list detailed items on your dash, such as fluids, belts, etc...
