R  B. If the test gives the maintenance message: 
R  BMC1 OR SOLENOID 10HA1 CKT 
R  NOTE : If the maintenance message BMC1 OR SOLENOID 10HA1 CKT comes into____ 
R  view with no associated ECAM warning, no trouble shooting 
R  procedure is necessary. 
R  - Do a check of the status of the circuit breaker (3HA1). 
R  (1) If the circuit breaker (3HA1) is closed: 
R  - Do a check for 28 VDC at pin A/1 of the connector of the bleed 
R  pressure regulator valve control solenoid (10HA1) with the ENG 1 
R  BLEED pushbutton switch (4HA1) released (OFF legend on). 
R  (a) If there is 28 VDC: 
R  - Do a check for ground at pin A/2 of the connector of the bleed 
R  pressure regulator valve control solenoid (10HA1). 
R  1_  If there is no ground signal:
R  - Repair the wiring from the pin A/2 to the ground point. 
R  2_  If there is a ground signal:
R  - Replace the SOLENOID-BLEED PRESS REG V CTL, ENG 1 (10HA1) 
R  (Ref. AMM TASK 36-11-55-000-001) and (Ref. AMM TASK 36-11-
R  55-400-001). 
R  (b) If there is no 28 VDC: 
R  - Do a check for 28 VDC at pin A/D2 of the ENG 1 BLEED pushbutton 
R  switch (4HA1). 
R  1_  If there is 28 VDC:
R  - Replace the P/BSW-ENG 1 BLEED (4HA1). 
R  a_  If the fault continues:
R  - Do a check and repair the wiring from the pin A/1 of the 
R  bleed pressure regulator valve control solenoid to the 
R  pin A/D3 of the ENG 1 BLEED pushbutton switch. 
R  2_  If there is no 28 VDC:
R  - Do a check and repair the wiring from the pin A/D2 of the 
R  ENG 1 BLEED pushbutton switch to the pin 2 of the circuit 
R  breaker 3HA1. 
R  a_  If the fault continues:
R  - Replace the AIR BLEED/ENG 1/CTL (3HA1). 
R  (2) If the circuit breaker (3HA1) is tripped: 
R  - Do the procedure (Ref. TASK 24-00-00-810-803).
