Visual Inspection

A visual inspection consists of physically looking for the possible cause of a malfunction. A careful and thorough visual inspection of components may quickly identify the cause of a malfunction and eliminate the need for diagnostic testing.

Perform the following visual inspections before doing any diagnostic testing. If a malfunction is not resolved by the visual inspection, proceed with diagnostic testing according to the instructions in this manual.
