3. Fault Confirmation
Subtask 23-73-00-710-070-A ** ON A/C NOT FOR ALL
A. Test
   (1) Do the CIDS1/PTP test through the CFDS.
4. Fault Isolation
Subtask 23-73-00-810-071-A ** ON A/C NOT FOR ALL
A. If the test gives a different maintenance message, do the trouble shooting procedure related to the maintenance message.
Subtask 23-73-00-810-158-D ** ON A/C NOT FOR ALL
B. If the CIDS1/PTP test gives the maintenance message NO P & TP DATA:
  • make sure that at least one cabin door is open,
  • make sure that the EMER LT (4WL) switch is in the OFF position,
  • open these CBs:
    49VU: 150RH (G01) COM DIR ESS/1
    49VU: 157RH (G02) COM DIR ESS/2
    121VU:151RH (M06) CIDS/DIR NORM/1
    121VU:156RH (M07) CIDS/DIR NORM/2,
  • stop for approx. 120 s,
  • do the CIDS2/PTP test.
   (1) If the CIDS2/PTP test does not give the message NO P & TP DATA:
Subtask 23-73-00-810-416-A ** ON A/C NOT FOR ALL
C. If the fault continues:
Subtask 23-73-00-810-417-A ** ON A/C NOT FOR ALL
D. If the fault continues:
  • do a check and repair the wiring between:
    CB 161RH and PTP connector A/17,
    DIR-CIDS (101RH) connector AA/F12 and PTP (110RH) connector A/1,
    DIR_CIDS (101RH) connector AA/G12 and PTP (110RH) connector A/2,
    DIR-CIDS (102RH) connector AA/F12 and PTP (110RH) connector A/6,
    DIR-CIDS (102RH) connector AA/G12 and PTP (110RH) connector A/7,
    DIR-CIDS (101RH) connector AA/J12 and PTP (100RH) connector A/4,
    DIR-CIDS (101RH) connector AA/K12 and PTP (110RH) connector A/5,
    DIR-CIDS (102RH) connector AA/J12 and PTP (110RH) connector A/4,
    DIR-CIDS (102RH) connector AA/K12 and PTP (110RH) connector A/5,
    PTP (110RH) connector A/3 and GND,
    PTP (110RH) connector A/8 and GND,
    PTP (110RH) connector A/16 and GND ASM 237323.
Subtask 23-73-00-810-159-A ** ON A/C NOT FOR ALL
E. Install the removed DIR-CIDS (101RH) AMM 23-73-34-400-001.
Subtask 23-73-00-810-485-A ** ON A/C NOT FOR ALL
F. Do the test given in Para. 3.A.
