Large electronic diesel engines used in the transport industry have a computer fault code system that is instrumental in diagnosing problems. In many cases the codes can be obtained easily but are 2 or 3 digit numbers that have no meaning to the driver or owner. Pocket fault codes will allow you to enter these codes and find out what they mean.
