Chapter 10 Isolating Failed Parts 183
5. Will the tool test the suspected source(s) of the problem?
Perhaps you already have some idea of what the problem is. If so, you want to
use a diagnostic tool capable of testing the suspected problem sources.
■ TABLE 6-5 tells you which replaceable hardware parts can be isolated by each
fault isolating tool.
■ TABLE 6-9 tells you which replaceable hardware parts are covered by each
system exercising tool.
6. Is the problem intermittent or software-related?
If a problem is not caused by a clearly defective hardware component, then you
may want to use a system exerciser tool rather than a fault isolation tool. See
Chapter 12 for instructions and “About Exercising the System” on page 105 for
background information.
