 (1) If the circuit breaker is closed:
 -do a check for 28VDC at pin A/1 of the bleed transferred pressure transducer (7HA2) (Ref. ASM 36-11/02).
 (a) If there is no 28VDC:
 -do a check for ground at pin A/2 of the bleed transferred pressure transducer (7HA2) (Ref. ASM 36-11/02).
 1 If there is no ground:
_
 -repair the wiring between pin A/2 of the bleed transferred pressure transducer (7HA2) and the ground (Ref. ASM 36-11/02).
 2 If there is ground:
_
 -do a check of the wiring between pin A/1 of the bleed transferred pressure transducer (7HA2) and the AIR BLEED/ENG2/MONG circuit breaker (2HA2) (Ref. ASM 36-11/02).
 a If there is no continuity:
_ -repair the wiring.
 b If there is continuity:
_ -replace the C/B-AIR BLEED/ENG 2/MONG (Ref. ASM 36-11/02).
 3 If the fault continues:
_
 -make sure that there is a 0 psig output signal (0.9VDC) at the BMC2 (1HA2) connector between pins AA/14B and AA/15B.
 a If there is no 0.9VDC:
_
 -replace the XDCR-BLEED TRANSFER PRESS, ENG 2 (7HA2) (Ref. AMM TASK 36-11-15-000-001) and (Ref. AMM TASK 36-11-15-400-001).
 4 If the fault continues:
_
 -do a check and repair the wiring between pins A/3 and A/4 of the bleed transferred pressure transducer (7HA2) and pins AA/14B and AA/15B of the BMC2 (1HA2) (Ref. ASM 36-11/02).
 (b) If there is 28VDC:
 -replace the XDCR-BLEED TRANSFER PRESS, ENG 2 (7HA2) (Ref. AMM TASK 36-11-15-000-001) and (Ref. AMM TASK 36-11-15-400-001).

 (2) If the circuit breaker is open:
 -close the circuit breaker.
 (a) If the circuit breaker trips:
 -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:
 - do a check of the wiring for a short to ground between pin
 A/1 of the bleed transferred pressure transducer (7HA2) and
 the AIR BLEED/ENG 2/MONG circuit breaker (2HA2) (Ref. ASM
 36-11/02).

 a If there is a short to ground:
_

 -repair the wiring. b If there is no short to ground:
_ -replace the C/B-AIR BLEED/ENG 2/MONG (Ref. ASM 36-11/02).

 (b) If the circuit breaker stays closed and the fault continues:
 -replace the BMC-2 (1HA2) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
 C. After the subsequent flight, make sure that the fault does not continue.

 A. Test
 (1) Do the BITE test of the BMC1 (Ref. AMM TASK 36-11-00-740-001).
 4. Fault Isolation
_______________
 A. If the BITE test gives the maintenance message:
 BMC1 OR BLEED FAULT IND 4HA1

 NOTE : If the maintenance message BMC1 OR BLEED FAULT IND 4HA1 comes into
____ view with no associated ECAM warning, no trouble shooting procedure is necessary.
 -Replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
