A. Test
(1) Do the BITE test of the BMC2 (Ref. AMM TASK 36-11-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
BMC2 OR BLEED FAULT IND 4HA2
NOTE : If the maintenance message BMC2 OR BLEED FAULT IND 4HA2 comes into
____ view with no associated ECAM warning, no trouble shooting procedure is necessary.
-Replace the BMC-2 (1HA2) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
(1) If the fault continues:
-Replace the P/BSW-ENG 2 BLEED (4HA2) (Ref. ASM 36-11/02).
(a) If the fault continues:
-Do a check and repair the wiring (Ref. ASM 36-11/02) between: . Pin A/C2 of the engine 2 bleed pushbutton switch (4HA2) and pin AA/4A of the BMC2 (1HA2) . Pin A/C2 of the engine 2 bleed pushbutton switch and pin AA/4A of the BMC2 . Pin A/C3 and the ground.

_______________
A. If the fault symptom is identified by the crew observation: ENG BLEED AIR - Loss of bleed air from engine 1
-Replace the engine 1 VALVE-PNEUMATIC STARTER (4005KS) (Ref. AMM TASK 80-11-20-000-003) and (Ref. AMM TASK 80-11-20-400-003).
(1) If the fault continues:
-Replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
(a) If the fault continues:
-Do a check of the wiring (Ref. ASM 36-11/01) between: . Pin 2 of the AIR BLEED/ENG 1/CTL circuit breaker (3HA1) and pin AA/8A of the BMC 1 (1HA1) . Pin 2 of the AIR BLEED/ENG 1/CTL circuit breaker and pin A/D2 of the ENG 1 BLEED pushbutton switch (4HA1) . Pin AA/7A of the BMC 1 and pin A/D1 of the ENG 1 BLEED pushbutton switch .
