code breaker!Reviewed by Anonymous on 26 Nov 2013

A very good book to have to aid diagnostic work. Contains all fault codes with an explanation for each one. Well written start to the book details how sensors operate which is extremely useful in understanding what may have gone wrong. A must have.
