- replace the DITCHING pushbutton switch (13HL).
(2) If the fault continues:
- do a check and repair the wiring from the DITCHING pushbutton switch (13HL) to the circuit breaker (1HZ), via the the relay (3HZ) (Ref. ASM 21-55/01).
R C. Do the test given in para. 3.

__________________
A. Do the operational test of the emergency ram air inlet (Ref. AMM TASK 21-55-00-710-001).
4. Fault Isolation
_______________
R A. If during the test the ram air symbol does not change from GREEN (CLOSED) R to AMBER (OPEN) within the maximum operation time of 20 seconds:
- replace the RAM AIR pushbutton switch (4HZ).
(1) If the fault continues:
- replace the RELAY-RAM AIR OPENING CTL (5HZ).
(2) If the fault continues:
- replace the RELAY-RAM AIR CLOSE CTL (3HZ).
(3) If the fault continues:
- replace the ACTUATOR-EMERGENCY RAM AIR INLET (7HZ) (Ref. AMM TASK 21-55-51-000-001) and (Ref. AMM TASK 21-55-51-400-001).
(4) If the fault continues:
- do a check and repair the wiring:
- from the EMERG RAM AIR ACTUATOR A/B, F to the SDAC-1 (1WV1) AA/9F, 10F,
- from the EMERG RAM AIR ACTUATOR A/B, F to the SDAC-2 (1WV2) AA/9F, 10F,
- from the EMERG RAM AIR ACTUATOR A/D, H to the GND,
- from the RAM AIR pushbutton switch (4HZ) A/J to the SDAC-1 (1VW1) AA/9G,
- from the RAM AIR pushbutton switch (4HZ) A/J to the SDAC-2 (1WV2) AA/9G,
- from the RAM AIR pushbutton switch (4HZ) A/D3 to the GND,
- from the EMERG RAM AIR ACTUATOR to the circuit breaker (1HZ), via the relay (5HZ), the RAM AIR pushbutton switch (4HZ) and the relay (3HZ).
(Ref. ASM 21-55/01) and (Ref. AWM 31-54-52).
R B. Do the test given in para. 3.
