R A. Test
Removal of the GCU-1(2) (1XU1, 1XU2)
Installation of the GCU-1(2) (1XU1, 1XU2)
Removal of the Contactors (9XU1, 9XU2, 11XU1, 11XU2)
Installation of the Contactors (9XU1, 9XU2, 11XU1,
11XU2)
Operational Check of GAPCU via CFDS
R (1) Do the BITE test of the GAPCU (Ref. AMM TASK 24-41-00-740-002).
R (a) If the BITE test gives the message TEST FAILED:
R - do the trouble shooting given in Para 4.A.
R (b) If the BITE test gives the message TEST PASSED:
R - do the trouble shooting given in Para 4.B. R 4. Fault Isolation
_______________
R A. If the BITE test gives the message TEST FAILED:
R - push the line key adjacent to the TEST FAILED message.
R (1) If the maintenance message GCU2 (1XU2) comes into view:
R - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref.
R AMM TASK 24-22-34-400-001).

R B. If the BITE test gives the message TEST PASSED:
R - do a check of the contact for correct operation of the GLC 2 (9XU2)
R between pins B/18 and B/20 (Ref. ASM 24-22/03).
R (1) If the contact does not operate correctly:
R - replace the GLC-2 (9XU2) (Ref. AMM TASK 24-22-55-000-001) and (Ref.
R AMM TASK 24-22-55-400-002) as necessary.
R (2) If the contact operates correctly:
R - do a check of the wiring of the GLC 2 sence circuit (Ref. ASM 24-
R 22/03) for an open circuit between:
R . pin 2 of the ELEC/GCU2 circuit breaker (2XU2) and pin B/18 of the
R GLC 2 (9XU1)
R . pin B/20 of the GLC 2 and pin A/30 of the diode module 2420VD
R . pin A/15 of the diode module 2420VD and pin A/6A of the GCU 2.
R (a) If the wiring is not correct:
R - repair or replace as necessary.
R (b) If the wiring is correct:
R - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and
R (Ref. AMM TASK 24-22-34-400-001).
R C. When you replace a component or repair the wiring:
R - do the subsequent flight before you do the check of the Class 3 Faults
R of the GAPCU from the CFDS to make sure that the system operates
R correctly.
R If the test continues to give the fault message, continue the trouble
R shooting procedure.
