3. Fault Confirmation
__________________
A. Test
(1) Do the BITE test of the TCAS (Ref. AMM TASK 34-43-00-740-001) and make sure that you can hear the synthesized voice message in the two loud speakers.
4. Fault Isolation
_______________
A. If you cannot hear the synthesized voice message:
(1) In the CAPT loud speaker only:
- replace the LOUD SPEAKER-CAPT (7WW) (Ref. AMM TASK 31-53-21-000-001) and (Ref. AMM TASK 31-53-21-400-001).
(a) If the fault continues:
- do a check and repair the wiring of the CAPT loud speaker (7WW): . pin A/R to the first terminal block . pin A/S to the first terminal block (Ref. ASM 34-43/01).
(2) In the F/O loud speaker only:
- replace the LOUD SPEAKER-F/O (8WW) (Ref. AMM TASK 31-53-21-000-001) and (Ref. AMM TASK 31-53-21-400-001).
(a) If the fault continues:
- do a check and repair the wiring of the F/O loud speaker (8WW): . pin A/R to the first terminal block . pin A/S to the first terminal block (Ref. ASM 34-43/01).
(3) In the two loud speakers:
- replace the CMPTR-TCAS (1SG) (Ref. AMM TASK 34-43-34-000-001) and (Ref. AMM TASK 34-43-34-400-001).
(a) If the fault continues:
- replace the RELAY-RCDR/CVR TEST (20RK).
1 If the fault continues:
_
- do a check of the wiring of the AUDIO OUTPUT discretes from the TCAS computer (1SG) to the RCDR/CVR test relay (20RK) (Ref. ASM 34-43/01).
a If there is no continuity:
_ - repair the above wiring.
b If there is continuity:
_
- do a check and repair the wiring of the RCDR/CVR test relay (20RK): . pin A/B to the first terminal block . pin A/C to the first terminal block (Ref. ASM 34-43/01).
B. Do the test given in Para. 3.

__________________
A. Test
Not applicable, you cannot confirm this fault on the ground.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the crew observation on the ND, TCAS-amber filled circle on the aircraft symbol or TCAS-false intruders:
- remove the TCAS computer (1SG) (Ref. AMM TASK 34-43-34-000-001)
- remove the ATC/Mode S transponder 1 (1SH1) (Ref. AMM TASK 34-52-33-000-001).
