4. Fault Isolation
_______________
A. If during the test with the engines not in operation, an abnormal bleed temperature is shown amber on the BLEED page of the lower ECAM DU:
-remove the BMC1 (1HA1) (Ref. AMM TASK 36-11-34-000-001)
-Do the test given in para. 3.
(1) If during the test, the abnormal bleed temperature is shown amber on the BLEED page for the engines 1 and 2: - on the connector 1HA2-AB, on the wiring side, make sure that there
is ground at pin 1B (Ref. ASM 36-11/02):
(a)
If there is ground at pin 1B:
-replace the BMC-2 (1HA2) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001)
-refer to Para. 4.B.
(b)
If there is no ground at pin 1B:
-do a check and repair the wiring from the connector 1HA2-AB/1B to the ground
-refer to Para. 4.B.
(2) If during the test, the abnormal bleed temperature is shown amber on the BLEED page for the engine 2 only:
-replace the SENSOR-EXCHANGER OUT TEMP, ENG 2 (6HA2) (Ref. AMM TASK 36-11-17-000-001) and (Ref. AMM TASK 36-11-17-400-001).
(a)
If the fault continues:
-do a check and repair the wiring from the connector 1HA2-AA/9B to the connector 6HA2-A/2 and wiring from the connector 1HA2-AA/10B to the connector 6HA2-A/4 (Ref. ASM 36-11/02)
-refer to Para. 4.B.
(b)
If the fault does not continue:
-refer to Para. 4.B.
B. Install the BMC1 (1HA1) (Ref. AMM TASK 36-11-34-400-001) and do the test given in Para. 3.
