A. If the BITE test gives the maintenance message:
FCDC1
(a) Do a check of the wiring of the 28VDC GND signal from the FCDC1 (3CE1) to the ground terminal ASM 279207.
wiring of the +28VDC signal from the FCDC1 (3CE1) to the first terminal block ASM 279207.
Subtask 27-95-00-740-083-A FCDC1
- replace the FCDC-1 [3CE1] AMM 27-95-34-000-001 and AMM 27-95-34-400-001.
(a) Do a check of the wiring of the 28VDC GND signal from the FCDC1 (3CE1) to the ground terminal ASM 279207.
- if there is no continuity repair the above wiring
- if there is continuity see the Para. (b).
B. Do the test given in Para. 3.
