A. If the ATC1 test gives the maintenance message ATC-1:NO DATA FROM TCAS, and if the TCAS test gives the maintenance message TCAS (1SG): - on the center pedestal, on the ATC/TCAS control unit, set the ATC2 to
on and do the BITE test of the ATC (system 2) (Ref. AMM TASK 34-52-00-740-004).
(1) If the test gives the maintenance message ATC-2:NO DATA FROM TCAS:
- replace the CMPTR-TCAS (1SG) (Ref. AMM TASK 34-43-34-000-001) and (Ref. AMM TASK 34-43-34-400-001)
- if the fault continues, do a check and repair the suppressor coaxial cable from the TCAS computer (1SG) pin AC/12 to the connector 150VC (Ref. AWM 34-43-05).
(2) If the test is OK, do the BITE test of the TCAS (Ref. AMM TASK 34-43-00-740-001):
- if the test is OK, do a check and repair the suppressor coaxial cable from the ATC transponder 1 (1SH1) pin AC/12 to the connector 150VC (Ref. AWM 34-52-03).

R if the TCAS test gives the maintenance message TCAS (1SG):
R - on the center pedestal, on the ATC/TCAS control unit, set the ATC2 to
R on and do the BITE test of the ATC (system 2) (Ref. AMM TASK 34-52-00-R 740-004).
R (1) If the test gives the maintenance message TCAS(1SG)/ ATC2(1SH2)
