_______________
A. If the test gives the maintenance message NO GPCU 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:
- do a check and repair the wiring from the CFDIU (1TW) pins AA/6F, 6G to the GPCU (1XG) pins AA/7D, 7C, (Ref. ASM 31-32/06).
(2) If the fault continues:
- do a check for 28VDC at GPCU (1XG) pin AB/15A (Ref. ASM 24-41/00).
(a) if there is 28VDC:
- replace the GPCU (1XG), (Ref. AMM TASK 24-41-34-000-001) and (Ref. AMM TASK 24-41-34-400-001).
(b) if there is no 28VDC:
- do a check for open or short to ground of the wiring between the C/B-ELEC/GPCU (7XG) and the GPCU (1XG) pin AB/15A.
1_ if there is an open or a short to ground:
- repair the defective wiring(s).
2_ if there is no open or short to ground:
- replace the defective C/B-ELEC/GPCU (7XG).
B. Do the test given in Para. 3.B.
