__________________
 A. Do a bite test on LGCIU 1 and LGCIU 2 (Ref. AMM TASK 32-69-00-740-001).
 4. Fault Isolation
_______________
 A. If the LGCIU 1 and LGCIU 2 display CFDS fault messages, replace the BSCU (10GG) (Ref. AMM TASK 32-42-34-400-001) and (Ref. AMM TASK 32-42-34-400-001).
 (1) Do the test (Ref. Para 3. A.).

 (2) If only one LGCIU displays CFDS fault messages, swap the LGCIU positions (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

 (3) If the fault moves with the LGCIU, swap back the LGCIU's and replace the defective LGCIU-1 (5GA1) or LGCIU-2 (5GA2) (Ref. Para 4. A. (2)).

 (4) If the fault stays in the same system, do a check for ground at the LGCIU 1(2) connector AA pin 9H (Ref. ASM 32-31/03) or (Ref. ASM 32-31/04).

 (5) If there is a ground, replace the LGCIU 1(2) (Ref. Para 4. A. (2)).

 (6) If there is no ground, do a check for ground at the relay 24GG(25GG) connector AA pin Z (Ref. ASM 32-42/01).

 (7) If there is a ground, replace the BSCU (Ref. para 4. A.).

 (8) If there is no ground, replace the relay 24GG(25GG).

 (9) Do a bite test of the LGCIU 1(2) (Ref. Para. 3. A.).
