A. If the test gives the maintenance message BCL2 : LGCIU/ADIRU1 SIGNAL DISAGREE:
NOTE : This CFDS message can be found with these CFDS messages:
____
. LGCIU1 or
. ADIRU1 and
BCL1 : LGCIU/ADIRU1 SIGNAL DISAGREE.
In this case, do the related trouble shooting.
If not, do the trouble shooting given below:
- do a check of the wiring for open circuit or short to ground: . from the pin A/g of the BCL2 to the first branch point. . between the pin A/K of the BCL2 and the pin B/4C of the LGCIU1 (Ref. ASM 24-24/02) and (Ref. ASM 24-38/01).
(1) If the wiring is not correct:
- repair it.
