Subtask 36-11-00-810-254-A ** ON A/C NOT FOR ALL
A. If fault message SAV (SW) J9/J10 ECU is found then:
Subtask 36-11-00-810-254-B ** ON A/C NOT FOR ALL - Do the trouble shooting procedure (Ref. TSM TASK 80-11-00-810-802).
- Replace the BMC-2 [1HA2] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- Do a check of the wiring ASM 361102 between:
. Pin 2 of the AIR BLEED/ENG 2/CTL circuit breaker (3HA2) and pin AA/8A of the BMC 2 (1HA2)
. Pin 2 of the AIR BLEED/ENG 2/CTL circuit breaker and pin A/D2 of the ENG 2 BLEED pushbutton switch (4HA2)
. Pin AA/7A of the BMC 2 and pin A/D1 of the ENG 2 BLEED pushbutton switch
. Pin A/D3 of the ENG 2 BLEED pushbutton switch and pin A/1 of the bleed pressure regulator valve control solenoid (10HA2)
. Pin A/2 of the engine 2 bleed pressure regulator valve control solenoid and the ground.
- Repair the wiring.
- Replace the P/BSW-ENG 2 BLEED [4HA2] .
- Replace the ENG/APU FIRE PNL [1WD] AMM 26-12-12-000-001 and AMM 26-12-12-400-001.
* If the fault continues:
* - Replace the SOLENOID-BLEED PRESS REG V CTL, ENG 2 [10HA2] AMM 36-11-55-000-001 and AMM 36-11-55-400-001.
A. If failure message SAV (SW) J9/J10 ECU is found then:
Subtask 36-11-00-710-409-A ** ON A/C NOT FOR ALL - Do the trouble shooting procedure (Ref. TSM TASK 80-11-00-810-802).
- Replace the BMC-2 [1HA2] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- Do a check of the wiring ASM 361102 between:
. Pin 2 of the AIR BLEED/ENG 2/CTL circuit breaker (3HA2) and pin AA/8A of the BMC 2 (1HA2)
. Pin 2 of the AIR BLEED/ENG 2/CTL circuit breaker and pin A/D2 of the ENG 2 BLEED pushbutton switch (4HA2)
. Pin AA/7A of the BMC 2 and pin A/D1 of the ENG 2 BLEED pushbutton switch
. Pin A/D3 of the ENG 2 BLEED pushbutton switch and pin A/1 of the bleed pressure regulator valve control solenoid (10HA2)
. Pin A/2 of the engine 2 bleed pressure regulator valve control solenoid and the ground.
- Repair the wiring.
- Replace the P/BSW-ENG 2 BLEED [4HA2] .
- Replace the ENG/APU FIRE PNL [1WD] AMM 26-12-12-000-001 and AMM 26-12-12-400-001.
* If the fault continues:
* - Replace the SOLENOID-BLEED PRESS REG V CTL, ENG 2 [10HA2] AMM 36-11-55-000-001 and AMM 36-11-55-400-001.
B. After the subsequent flight, make sure that the fault does not continue.
