M2/M3 BFV: FIRE SUPPRESSION SYST - OD1607 - LESSON 2/TASK 2
initial test does not reveal a fault in the system, a pathway is then
followed which will lead to a determination of "no faults found". If
the initial tests indicate that a malfunction is present in the fire
suppression system, troubleshooting pathways will be explored to
determine which component is faulty so that the problem can be
corrected. The test is then repeated to verify that all faults have
been found and corrected.

Troubleshooting the Fire Suppression System
As with many troubleshooting tasks, the task of troubleshooting the
fire suppression system on the M2/M3 Bradley fighting vehicle
requires the mechanic to perform tests and respond to the results of
those tests by performing more tests until the faulty component has
been isolated.
The test results can branch off into many different
areas of the vehicle as various components are eliminated as being
the possible cause of the trouble.
It would be confusing and
impractical to attempt to describe all the troubleshooting pathways.
Therefore, this subcourse will deal with only a few of the major
pathways that develop in this troubleshooting task.
Since the troubleshooting procedures for the fire suppression system
are also used to test the system for proper operation, one of the
pathways will indicate tests and test results that can be expected if
everything in the system is working properly and no faults are found.
This pathway, which will be identified as pathway one in this
subcourse, is also used to verify that a problem has been solved once
a faulty part has been identified and replaced.
Two other major
pathways that could be encountered when there are problems present in
the fire suppression system will then be explored in the subcourse.
Because the objective of this portion of the subcourse is to
illustrate the methods used to troubleshoot the fire suppression
system on the M2/M3 Bradley fighting vehicle, the procedures
necessary to replace faulty components will not be covered here.
Instead, reference will be made to the technical manual (TM) where
the replacement procedures can be found.
