General Troubleshooting Procedures
a.
General.  When equipment malfunctions, it is not always obvious
what  is  causing  the  problem.
A  description  as  general  as  "the
steering  system  does  not  work"  does  not  point  directly  to  the
specific  malfunctioning  component  so  that  the  problem  can  be
repaired.
Knowing  how  to  isolate  the  faulty  component  is  an
essential part of materiel maintenance.
This process of systematic
isolation of defective components by analyzing trouble symptoms and
testing for defective components so that corrective action can be
taken is known as troubleshooting.
Troubleshooting, in the general
sense, is a logical thought process.  When applied methodically, this
thought process leads to the identification of defective parts so
that the malfunctioning equipment can be repaired.
The general description of troubleshooting methods can be outlined in
four steps.  First, it must be verified that the reported problem is
present  in  the  vehicle.
The  symptoms  of  the  problem  must  be
identified,  verified,  and  analyzed.
Second,  the  fault  must  be
isolated.  This is done by applying the knowledge gained in step one
to identify the system in which the malfunction is occurring and then
to methodically test components in that system which could be causing
the problem.
Third, once the fault has been isolated, it will be
necessary to correct the fault by repairing, adjusting, or replacing
defective components.
Finally, it is necessary to verify that the
problem no longer exists and that there are no other problems.
b.
Symptom Analysis.  The first step in the general troubleshooting
method may be called symptom analysis.
It consists of getting as
much information as possible to help identify the specific nature of
the symptoms causing the malfunction and analyzing those symptoms.
The  information  needed  to  analyze  the  trouble  symptoms  can  be
obtained by reading DA Form 2404, interviewing the vehicle crew, and
test  operating  the  malfunctioning  equipment.
Then,  it  would  be
necessary to look up the vehicle system where the problem is located
in the task index beginning on page 3-15 of TM 9-2350-252-20-1-1.
