CES 4. Fault Isolation
_______________
A. If the test gives the maintenance message:
SDAC2: NO CPC1 ANALOG SIGNAL
- replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(1) If the fault continues:
- do a check of the wiring from SDAC 2 (1WV2) pins AB/10C, 10D to the first terminal block (Ref. ASM 31-54/02).
(a) If there is no continuity:
- repair the above wiring.
(b) If there is continuity:
- do a check of the wiring from SDAC 2 (1WV2) pins AE/10E, 10F to the first terminal block (Ref. ASM 31-54/02).
1 If there is no continuity:
_
- repair the above wiring.
2 If there is continuity:
_
- do a check of the wiring from SDAC 2 (1WV2) pins AE/10G, 10H to the first terminal block (Ref. ASM 31-54/02).
a If there is no continuity:
_ - repair the above wiring.
(2) If the fault continues:
(a) replace the VALVE-OUTFLOW (10HL), FEEDBACK ASSEMBLY (if installed) (Ref. AMM TASK 21-31-51-000-005) and (Ref. AMM TASK 21-31-51-400-005).
(b) If the fault continues:
- replace VALVE-OUTFLOW (10HL) (Ref. AMM TASK 21-31-51-000-001) and (Ref. AMM TASK 21-31-51-400-001).
B. Do the test given in Para. 3.B.
