M2/M3 BFV: FIRE CONTROL SYSTEM - OD1608 - LESSON 2/TASK 4
NOTE
During
the
test
procedure,
the
STE
set
communicator (SETCOM) may display instructions
referring to one of several indexes.
The
contents of these indexes will not be reproduced
in this subcourse.
Instead, reference will be
made to the technical manual in which the index
can be found, when needed.
NOTE
During the test procedure, several pathways
develop depending on the results obtained for
individual tests being run.
Not all pathways
will be covered in this subcourse.
One typical
pathway will be used as an example.
When
actually performing the test on the vehicle, be
sure to have the TM 9-2350-252-20-2-1 on hand and
respond to the actual test results observed
during testing.
a. Preparing for Test 2731. Before beginning to run test 2731 on
the ISU night vision system, make sure that the engine is stopped,
the turret is shut down, and the weapons are unloaded and safe. Then
perform these initial steps:
(1) Hook up the STE-M1/FVS test set to the diagnostic panel, as
described in lesson 2, task 1 on this subcourse (paragraph 4a
beginning on page 66).
(2) Perform the STE self-test (lesson 2, task 1, paragraph 5
beginning on page 71).
(3) If any faults are found during the STE self-test, refer to
the symptom index table in TM 9-4910-751-14-1, page 5-1.
(4) If no faults are found during the STE self-test, proceed
with test 2731.
b. Running Test 2731. To run test 2731, enter 2731 on the SETCOM
and wait for the SETCOM response.
