M2/M3 BFV: TROUBLESHOOTING - OD1610 - LESSON 1/TASK 1
Troubleshooting in General
In the introduction to this task, we touched briefly on the definition of
the word troubleshooting.
In addition, we added the word logical to that
definition, which Webster's New World Dictionary defines as "based on or
using logic." Logic is defined as "correct reasoning." Therefore, logical
troubleshooting is using correct reasoning to investigate and detect the
cause of equipment malfunction.
Logical troubleshooting, therefore, uses a set course of action to arrive at
a conclusion. In the paragraphs that follow, we will discuss the steps that
comprise this course of action.
The purpose of troubleshooting is to identify, locate,
isolate and correct malfunctions that occur within equipment. It does not
matter whether that piece of equipment is an M1 tank or a child's bicycle;
with a few minor adjustments, the procedure is always the same.
b. There are four main steps that will be performed in unit
Several of these main steps have sub-steps that are
performed in sequence; the completion of all the sub-steps in the sequence
indicates the completion of the main troubleshooting step.
Each of these
main steps and associated sub-steps will be discussed in the paragraphs that
(1) Verify Existence of Malfunction.
The very first step in any
troubleshooting procedure, whether for a car, truck, tank, weapon, etc., is
to verify the existence of the malfunction. This is done in several ways,
which will be discussed in the paragraphs that follow.
(a) Read DA Form 2404. The very first step in troubleshooting is
to read DA Form 2404, Equipment Inspection and Maintenance Worksheet. This
form is used to record faults found during the operator's inspection,
periodic preventive maintenance checks and service (PMCS), inspection of
equipment by maintenance activities, diagnostic check-outs, and spot check
inspection of equipment.
The form is also used to record the results of
technical evaluations and inspections and to record the work performed to
correct a malfunction.
