Subtask 36-11-00-810-253-A ** ON A/C NOT FOR ALL
A. If fault message SAV (SW) J9/J10 ECU is found then:
Subtask 36-11-00-810-253-B ** ON A/C NOT FOR ALL - Do the trouble shooting procedure (Ref. TSM TASK 80-11-00-810-801).
- Replace the BMC-1 [1HA1] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- Do a check of the wiring ASM 361101 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
. Pin A/D3 of the ENG 1 BLEED pushbutton switch and pin A/1 of the bleed pressure regulator valve control solenoid (10HA1)
. Pin A/2 of the engine 1 bleed pressure regulator valve control solenoid and the ground.
- Repair the wiring.
- Replace the P/BSW-ENG 1 BLEED [4HA1] .
- 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 1 [10HA1] AMM 36-11-55-000-001 and AMM 36-11-55-400-001.
A. If failure message SAV (SW) J9/10 ECU is found then:
Subtask 36-11-00-710-407-A ** ON A/C NOT FOR ALL - Do the trouble shhoting procedure (Ref. TSM TASK 80-11-00-810-801).
- Replace the BMC-1 [1HA1] AMM 36-11-34-000-001 and AMM 36-11-34-400-001.
- Do a check of the wiring ASM 361101 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
. Pin A/D3 of the ENG 1 BLEED pushbutton switch and pin A/1 of the bleed pressure regulator valve control solenoid (10HA1)
. Pin A/2 of the engine 1 bleed pressure regulator valve control solenoid and the ground.
- Repair the wiring.
- Replace the P/BSW-ENG 1 BLEED [4HA1] .
- 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 1 [10HA1] 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.
