One of the biggest changes in today’s automotive industry is the idea of a “tune-up.” For many vehicle owners, the definition of a tune-up varies. Tune-ups protect against future engine complications, while recognizing and replacing worn out parts. Keeping a regular tune-up timetable will help your vehicle last much longer, sustain a higher gasoline mileage, and boost efficiency.
In the past, tune-ups consisted of the routine replacement of key ignition system parts like spark plugs and ignition points, and other basic adjustments to help “tune” the engine. Mounting pressure for increased fuel economy and lower emissions drove the car manufacturers to adopt electronics. This eliminated the need for the replacement and adjustment of a growing number of ignition and fuel system parts.
As the pace of technology quickened, the procedures required to perform a traditional tune-up changed dramatically. Highly sophisticated ignition and fuel systems are now the norm. These systems use one or more on-board computers to control critical engine and transmission management functions. Through on-board computer technology, things that were once handled mechanically, are now controlled electronically.
The classic “tune-up” was once the heart of the automotive business. Contrary to some beliefs, today’s modern vehicles still need tune-ups to keep them performing at the most efficient levels. The Car Care Council has now introduced the 21st Century Tune-up. It is designed to help re-define and educate motorists as to what a tune-up should consist of on today’s modern vehicles.
According to the 21st Century Tune -up, the following systems should be inspected:
Battery, charging and starting
Power-train control (including on-board diagnostic checks)
