Subtask 23-73-00-810-152-D ** ON A/C NOT FOR ALL
B. If the fault continues:
  • 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,
  • wait for approx. 10 s and close the CBs 156RH and 157RH.
  • stop for approx. 120 s,
  • do the PTP test again.
   (1) If the test is OK:
Subtask 23-73-00-810-153-A ** ON A/C NOT FOR ALL
C. If the fault continues:
  • do a check and repair the wiring between:
    CB 161RH and the PTP (115RH) connector A/17,
    DIR-CIDS (101RH) connector AA/F12 and PTP (115RH) connector A/1,
