(6) Do the pre-conditioning with the APU (Ref. AMM TASK 12-33-21-618-001) and make sure that you do not smell fumes in the cabin and/or there is no oil smoke at the APU exhaust.
- if you smell smoke in the cabin, do the applicable trouble shooting procedure(Ref. TASK 49-00-81-810-874).
(7) Do a leak check and make sure that there is no fuel leak and/or no oil leak on the APU and/or the APU generator.
NOTE : Do the leak check with a black light lamp.

3. Fault Confirmation
__________________
A. Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-010). Do a check of the APU GEN electrical-parameter indications on the lower ECAM DU (APU Page).
4. Fault Isolation
_______________
A. Maintenance Action
(1) If all electrical parameter indications are replaced by amber XX:
- do the trouble shooting of the connection between the EGIU-2 (22XU2) and the SDAC 1 and 2 (1WV1(2)) and/or the APU GCU (1XS) (Ref. TASK 24-22-00-810-808).
(2) If one or two electrical parameter indications are replaced by amber
XX:
- replace the GCU-APU (1XS) (Ref. AMM TASK 24-23-34-000-001) and (Ref. AMM TASK 24-23-34-400-001).
(a) If the fault continues:
R - replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
