Now Anyone Can Solve the Mysteries of Auto Repair.

Long gone are the days when setting the points, checking the timing and cleaning spark plugs was all you had to do to get your car to run right. Today's cars are sensitive, computerized machines that require sophisticated equipment to diagnose and keep running in top condition. Starting in the mid 90's car manufacturers began equipping their vehicles with OBDII systems which governed complete control of the car. OBD-II enables manufacturers to control the stiff emissions standards governed by the EPA. Starting January 1,1996 all cars built have OBD-II systems, although not all conformed 100%. Usually it is the vehicles' Check Engine light that ultimately alerts the driver that there may be a problem with the vehicle. Due to the vast number of components that keep the Vehicle compliant with the emissions standard it is not financially feasible to just "Start Replacing Parts". At first the equipment required to diagnose OBD-II system signals was cost prohibitive and only repair shops could afford them. Today, however there is are now more affordable, user friendly diagnostic scanning devices so that each professional technician and home mechanic can have one in their tool box
