M2/M3 BFV: TROUBLESHOOTING - OD1610 - LESSON 2/TASK 1
Substituting cable CX305 for CX304 in this way will help the test set to
determine whether the faulty component is cable CX304 or TA301.

connection carefully because the pins can be bent or broken.

the message FAULTY CX304 appears on the display, replace cable CX304 and
repeat the self-test.
If 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 is
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.

cable CX305, as discussed in paragraph 3e(2)(f) on the following page.
