(c) Do a check (Ref. AWM 28-46-01) of the aircraft wiring (FLSCU-2 BITE 1 test command line) between the FLSCU-2 rack connector AA, pin 15B and the FQIC rack connector AB, pin 12F.
(d) Do a check (Ref. AWM 28-46-03) of the aircraft wiring (FLSCU-2 LS7 output line) between the FLSCU-2 rack connector AB, pin 3A and the FQIC rack connector AC, pin 1C.
(e) Repair all the unserviceable wiring and connectors.
(f) Do the test in Para. 3.A.
(4) If the fault continues or if the resistance of the dummy sensor is not in range in Step (1):
(a) Replace the CTR TK HIGH LVL DUMMY SENSOR (6QJ).
(b) Do the test in Para. 3.A.
