A. If the test gives the message LRU TEST NOT COMPLETED:
1 If there is no continuity:
Subtask 22-66-00-710-171-A - replace the FAC-1 [1CC1] AMM 22-66-34-000-002 and AMM 22-66-34-400-002.
- do a check of the
wiring of the ENG OWN STP and ENG OPP STP discretes (from the FAC 1 (1CC1) to the diode module (1801VD)) ASM 226801.
- repair the above wiring.
- do a check of the
wiring of the diode module (1801VD) :
. from pin A/5 to the first terminal block
. from pin A/13 to the first terminal block
1 If there is no continuity:
- repair the above wiring.
- replace the DIODE MODULE 1801VD .
B. Do the test given in Para. 3.
