3. Fault Confirmation
__________________
A. Test
(1) Do the operational test of the HF system (Ref. AMM TASK 23-11-00-710-001).
NOTE : Do the transmission test for more than 60 s to see the ECAM
____ warning on the upper ECAM DU. (The COM HF 2 EMITTING message comes into view after 60 s of continuous transmission).
NOTE : Do this test at each crew station to find which station is
____
related with the failure.
NOTE : Do this test for the HF 2 system only.
____
NOTE : At the end of the test (before you do the fault isolation
____ procedure), make sure that these controls are not in the transmit position:
- the HF 2 transmission pushbutton switch on an Audio Control Panel
- a radio PTT switch on one of the two side sticks
- a radio PTT pushbutton switch
- a hand mike selector.
4. Fault Isolation
_______________
A. Table of the circuit breakers used in this procedure:
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------
R **ON A/C 051-099, 201-210, 301-399,
121VU COM NAV/HF2 1RE2 L13
R **ON A/C 051-099, 201-210, 301-399, 401-499,
B. After 60 s, when the HF 2 transmission stops, this ECAM warning does not go out of view:
- COM HF 2 EMITTING.
(1) If the above warning does not go out of view after action on the HF 2 transmission pushbutton switch (green bars off) (on the ACP of the related station):
- go to Para. 4.B.

(2) If the above warning goes out of view after action on the HF 2 transmission pushbutton switch (green bars off) (on the ACP of the related station):
- go to Para. 4.C.
C. Open the circuit breaker 1RE2 on the panel 121VU, then close it.
(1) If the fault continues:
- do a check for ground at the pin AB/2E of the HF 2 transceiver (3RE2) (Ref. ASM 23-11/02).
(a) If there is no ground signal at this pin:
- do a check and repair the wiring from HF 2 transceiver(3RE2) pin AB/2E to the first terminal block (Ref. ASM 23-11/02).
(b) If there is a ground signal at this pin:
- replace the XCVR-HF, 2 (3RE2) (Ref. AMM TASK 23-11-33-000-001) and (Ref. AMM TASK 23-11-33-400-001).
1 If the fault continues:
_
- replace the AMU (1RN) (Ref. AMM TASK 23-51-34-000-001) and (Ref. AMM TASK 23-51-34-400-001).
2 If the fault continues:
_
- do a check and repair the wiring between AMU (1RN) pin AA/5F and HF 2 transceiver (3RE2) pin AB/1C (Ref. ASM 23-51/06).
- go to Para. 4.D.
D. The fault is at one of the 3 crew stations.
(1) If the fault is at the Captain station:
- do a check of continuity between pin AA/9J and pin AA/9K of the AMU (1RN) (Ref. ASM 23-51/02).
(a) If there is continuity between the two pins:
- replace the SW-RAD PTT, CAPT (11RN) (Ref. AMM TASK 27-92-41-000-001) and (Ref. AMM TASK 27-92-41-400-001).
1 If the fault continues:
_
- replace the AMU (Ref. AMM TASK 23-51-34-000-001) and (Ref. AMM TASK 23-51-34-400-001).
2 If the fault continues:
_
- do a check and repair the wiring between AMU (1RN) pins AA/9J, 9K and pins 1, 2 of the radio PTT switch (11RN) (Ref. ASM 23-51/02).
