M2/M3 BRADLEY FIGHTING VEHICLE: TURRET - OD1609 LESSON 3/TASK 2
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 follow-on
procedures listed below should be performed.
If the test is a repeat or the symptom has been corrected, move the
TURRET POWER switch to OFF.
Turn OFF the MASTER POWER switch.
Remove the STE test set from the diagnostic panel.
If they were removed during earlier test procedures, install the turret
floor plates (TM 9-2350-252-20-2-2, page 4-22).
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 2650 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
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.
If no problems are found in wiring harness 2W202 tests during test 2390,
perform test 2391 on 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.
