SETCOM display does not read 65020 or 65033, refer to the symptom index table in TM
9-4910-751-14-1, page 5-1).

the SETCOM response.
If the SETCOM displays a cable instruction message word number, refer to
the message word number index found on page 3-553 of TM 9-2350-252-20-2-1 and
follow the SETCOM instructions.

subcourse, that the SETCOM does not display a cable instruction message word
If the SETCOM displays a fault message, it would be necessary to refer to
the fault number index found on page 3-605 of TM 9-2350-252-20-1. However, assume
again that no fault message is displayed.
The third possibility is that the display will show a NO FAULTS FOUND
When a NO FAULTS FOUND message appears on the display, move the TURRET
POWER switch and MASTER POWER switch to OFF. Remove STE-M1/FVS from the diagnostic
panel. If required, install the center and right turret floor plates (TM 9-2350-
252-20-2-1, page 4-22).
Whenever a corrective action has been taken in the test and inspection procedure,
test 2700 should be performed again to see if the symptom has been corrected. This
should be continued until a NO FAULTS FOUND condition exists.
