C. Check for dash on engine parameters on ECAM display
4. Fault Isolation
Subtask 73-20-00-810-290-A
A. If the fault is confirmed:
(1) Disconnect J1 and J7 connectors from EEC2.
(a) Do a continuity check of connectors J1 and J7 between pins T and Q
(b) Do a continuity check of connectors J1 and J7 between pins T and R
(c) if fault found, do step 4.A.(2).
(d) if no fault found, do step 4.A.(3).
(2) Disconnect the connector 407VC2 in pylon (424).
(a) Check configuration of 407VC2 Ref. ASM 73-25-05 and Ref. AWM 73-25-03.
(3) If the fault continues:
· Inspect harness between EEC2 and 407VC2 Ref. AMM 71-50-00-210-010
· Check connection of connectors J1, J7 and 407VC2 Ref. AMM 70-23-15-912-010
· Check pin retention of connectors J1,J7 and 407VC2 (Ref. ESPM 20-48-23)
· Repair as necessary.
