STOP and then CLEAR.
Then replace the CIB, in accordance with TM
9-4910-751-14-1, and repeat the self-test.
If the message reads
REMOVE CX304 AND PLUG TA301, remove plug TA301 from cable CX304.

5 When plug TA301 and cable CX304 have been removed,
press the GO key.
The message on the display should read CONNECT
CX305 TO CIB J2. Substituting cable CX305 for CX304 in this way will
help the test set to determine whether the faulty component is cable
CX304 or plug TA301.
Plug the CX305-P2 connector into the J2
connector on the CIB.
Remember to make the connection carefully

CX304 and repeat the self-test.
(e) When the self-test did not detect any problems with cable
CX304, and the message REMOVE PLUG TA301 FROM CX304 appeared on the
display, plug TA301 was removed from cable CX304. In this case, the
next step is to press the GO key.
The message TEST IN PROGRESS
PLEASE WAIT should appear on the display.
(f) Wait for the display to change.
If the display reads
CX304 OK, the self-test has detected no problems in cable CX304. In
this case, proceed to test cable CX305, as discussed in paragraph
5c(6) below.
However, if the message REMOVE CX304 FROM CIB J1
