4. Fault Isolation
Subtask 73-20-00-810-289-A
A. If the fault is confirmed:
(1) Disconnect J1 and J7 connectors from EEC1.
(a) Do a continuity check of connectors J1 and J7 between pins T and R
(b) Do a continuity check of connectors J1 and J7 between pins T and Q
(c) if fault found, do step 4.A.(2).
(d) if no fault found, do step 4.A.(3).
(2) Disconnect the connector 407VC1 in pylon (414).
(a) Check configuration of 407VC1 Ref. ASM 73-25-04 and Ref. AWM 73-25-03.
(3) If the fault continues:
· Inspect harness between EEC1 and 407VC1 Ref. AMM 71-50-00-210-010
· Check connection of connectors J1, J7 and 407VC1 Ref. AMM 70-23-15-912-010
· Check pin retention of connectors J1,J7 and 407VC1 (Ref. ESPM 20-48-23)
· Repair as necessary. [Rev.6 from Feb 2017] 2026.04.04 04:36:14 UTC
