Why use an OBDII reader?
Although one does not repair cars, you can save money by themselves to diagnose your car. It is now possible even to read out any error codes and decide whether it is a transient error you want to reset itself, so "check engine " light does not light up anymore.
You can also use the reader to check a car before purchase. Not all errors on the motor results in the "check engine " light Fault Code Reader allows you to see these errors!
This product can of course also be used by professional mechanics who are tired of that hassle of wires.
