A. If the test gives the maintenance message ATC1(1SH1) +
ATC2(1SH2)/TCAS(1SG):
- do the BITE test of the ATC (Ref. AMM TASK 34-52-00-740-004).
(1) If the test gives a maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
(2) If the test does not give a maintenance message:
- 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 XPDR-ATC/MODE S, 1 (1SH1) and the XPDR-ATC/MODE S,2 (1SH2) (Ref. AMM TASK 34-52-33-000-001) and (Ref. AMM TASK 34-52-33-400-001).
