It is necessary to recognise that something is not operating correctly by applying your knowledge of the system, and then by applying this knowledge further and combining it with the skills of diagnostics, to be able to find out why.

Examples of fault-finding charts are also included. In the main, references will be to generic systems rather than to specific vehicles or marques.
