6.3How Defective Items are Indicated

When the flowcharts lead to a possible cause, this is indicated by a statement giving the name of the defective part or the cause of the problem, e.g. a defective SPU board is indicated by the statement “SPU.” When there are more possible items, they are listed in order of decreasing probability.
