1-134 Figure 1-46.—Combination displays. Six-Step Troubleshooting Procedure You may have the job of maintaining or helping to maintain some electrical or electronic unit, subsystem, or system. Some of these jobs may be complex, but even a complex job can be broken down into simple steps. Basically, any repair of electric or electronic equipment should be done in the following order: 1.    Symptom recognition. This is the action of recognizing some disorder or malfunction in electronic equipment. 2.    Symptom elaboration. Obtaining a more detailed description of the trouble symptom is the purpose of this step. 3.    Listing probable faulty functions. This step is applicable to equipment that contains more than one functional area or unit. From the information you have gathered, where could the trouble logically be located? 4.    Localizing the faulty function. In this step you determine which of the functional units of the multiunit equipment is actually at fault.
