In my point of view,the maintenance of the digital systems of an automobile is very important.
Traditionally speaking,the digital system of an automobile includes rechargeable battery,spark plug,power generator and etc.Rechargeable battery while in use will generate corrosive gas which is discharged through the vents on the battery and becomes one of causes of possible corrosion.The charcoal and grease accumulated on the two anodes on the tip of spark plug from dirty fuel will diminish the spark produced between two anodes and therefore decrease the output power of engine.Engine is an endurable part,but to keep it in good shape,we need to check regularly the belt connecting engine and power generator for its proper elasticity.A loosed belt will slip off from its original position,making engine stop running.In addition,we need to check the two charcoal brushes on power generator for its wearing condition,and replace them when necessary.
In all,to prevent us from getting into the situation mentioned above,the maintenance of digital systems is very important.
