M2/M3 BRADLEY FIGHTING VEHICLE: TURRET - OD1609 LESSON 3/TASK 2
(3)
The third possibility is that the display will show a NO FAULTS FOUND
message. When this is the case, two questions must be asked before the procedure
can continue. Is the test being repeated? Has the symptom been corrected? If the
test is being run for the first time and the symptom has not been corrected,
further testing is required. If the test is being repeated, or if the test is not
being repeated but the fault symptom that prompted the test has been corrected, the
test is essentially complete. In this case, the following procedures listed below
should be performed.
Step 1.
If the test is a repeat, or the symptom has been corrected, move the
TURRET POWER switch to OFF.
Step 2.
Turn OFF the MASTER POWER switch.
Step 3.
Remove the STE test set from the diagnostic panel.
Step 4.
If they were removed during earlier test procedures, install the center
and right turret floor plates (TM 9-2350-252-20-2-2, page 4-22).
c.
Test Continuation - Isolating a Fault.
When the SETCOM display shows a NO
FAULTS FOUND message, but a fault is present in the system (i.e., the symptom which
caused the test to be run in the first place is still present), it will be
necessary to perform more tests to isolate the component that is causing the
malfunction. When the component causing the problem has been located and repaired
or replaced, test 2525 should be repeated to verify a NO FAULTS FOUND condition.

Testing Wiring Harness 2W202.
This time the first suspect component is
wiring harness 2W202. To see if wiring harness 2W202 is good, tests 2390 and 2391
are run:
(a)
Perform test 2390 between plug 2W202P1 and jack 2W202J1.
If the test
shows that wiring harness 2W202 is not good, replace the wiring harness, following
the procedures in TM 9-2350-252-20-2-2, page 5-305.
(b)
If no problems are found in wiring harness 2W202 tests during test 2390,
perform test 2391 on jack 2W202J1 at diagnostic panel J3. If the test shows that
wiring harness 2W202 is not good,
