(1) If the valve symbol is green:
- do a check and repair the wiring between the AEVC (10HQ) and the skin air-inlet valve (15HQ), pin AA/4B and pin A/C and/or pin AA/4A and pin A/A (Ref. ASM 21-26/03).
(2) If the valve symbol is amber:
- do a check and repair the wiring between the AEVC (10HQ) and the skin air-inlet valve (15HQ), pin AB/4B and pin A/M and/or pin AB/4A and pin A/J (Ref. ASM 21-26/03).
(3) If the fault continues:
- replace the VALVE-SKIN AIR INLET, AVNCS VENT (15HQ) (Ref. AMM TASK 21-26-52-000-001) and (Ref. AMM TASK 21-26-52-400-001).
