NOTE : As the GEN APU was set to OFF because of a true failure, the fault
____
confirmation is not necessary.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the CFDS message : CHECK GLC APU AND/OR CONTROL CKT and the warning APU GEN FAULT on the upper ECAM display unit:
- do a check of the status of the APU GCU circuit breaker.
(1) If the circuit breaker is open:
- refer to (Ref. TASK 24-20-00-810-838).

201-299, 301-399, Aug 01/05 CES (2) If the circuit breaker is closed:
- do a check of the wiring between respectively: . the pin B/2D of the APU GCU and the pin B/3 of the APU GLC, through relays (5XG, 4XS), BTC1, BTC2, GLC1, CLC2, EPC . the pin B/2D and the pins A/12D, A/6A, A/13D of the APU GCU, . the pin A/12C of the APU GCU and the pin X1 of the APU GLC auxiliary control relay (4XS), via the ELEC/APU GEN pushbutton switch (2XS), . the pin X2 of the APU GLC auxiliary control relay and the ground, . the pin B/5 of the APU GLC and the ground, (Ref. ASM 24-23/02).
(a) If the wiring is not correct:
- repair it.
(b) If the wiring is correct:
- replace the GLC-APU (3XS) (Ref. AMM TASK 24-23-55-000-001) and (Ref. AMM TASK 24-23-55-400-001) .
(c) If the fault continues:
- replace the RELAY-APU GLC AUX CTL (4XS).
(d) If the fault continues:
- replace the GCU-APU (1XS) (Ref. AMM TASK 24-23-34-000-001) and (Ref. AMM TASK 24-23-34-400-001).
B. Make sure that the aircraft electrical circuits operate correctly in APU configuration.
(1) Energize the aircraft electrical circuits from the APU (Ref. AMM TASK 24-41-00-861-002).
(2) De-energizee the aircraft electrical circuits from the APU (Ref. AMM TASK 24-41-00-862-002).
