A. If the test gives the maintenance message NO PHC1 DATA:
- replace the CFDIU (1TW) (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(1) If the fault continues:
- replace the PHC-1 (6DA1) (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
(2) If the fault continues:
- do a check and repair the wiring from the CFDIU (1TW) to the PHC 1 (6DA1) from pins AA/11D, 11E to pins A/M, N (Ref. ASM 31-32/06).
B. Do the test given in Para. 3.B.
