 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.
