(2) If one or both of the reports, LAST LEG REPORT, PREVIOUS LEG REPORT gives the maintenance message which follows,
- OUTFLOW VALVE ELEC 2 (52) but the test cannot confirm the fault:
- replace the VALVE-OUTFLOW (10HL), ELECTRONIC MODULE 2 (referred to as OFV (10HL)) (Ref. AMM TASK 21-31-51-000-002) and (Ref. AMM TASK 21-31-51-400-002).
NOTE : The electronic module 2 is connected to the electrical
____ connector 10HL-B.
(3) If the fault continues:
- swap the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(a) If the fault moves with the CPC 2:
- swap back the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
- replace the CONTROLLER-CABIN PRESSURE 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(b) If the fault does not move with the CPC 2:
- swap back the CPC 1 (11HL) and the CPC 2 (12HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
- do a check and repair the wiring from the: OFV connector (10HL-B) pins R, P, N and M to the CPC 2 connector (12HL-AA) pins 7A, 8A, 9A and 10A (Ref. ASM 21-31/02).
- do a check of the earthing resistance at the return ground connections (Ref. AMM TASK 21-31-00-760-001) on:
1_ the CPC 2 connector 12HL-AC, pin 2 and on,
2_ the electronic module 2 connector 10HL-B, pin J.
NOTE : The resistance value must be smaller than 20 m.ohms.
