- make sure that there is continuity on the coaxial cable between the MMR1 and the localizer antenna 1/2 (3RT) (Ref. ASM 34-36/01)
- replace the coaxial cable if necessary
- make sure that there is discontinuity between the core and the shield of the coaxial cable
- repair if necessary
- install the MMR1
- install the localizer antenna 1/2 (3RT) (Ref. AMM TASK 34-36-11-400-001).
(2) If the test of the MMR1 does not give the maintenance message LOCALIZER ANTENNA (3RT)/COAX CABLE/MMR1(40RT1):
- replace the MMR that you installed on side 2.
B. If the test of the MMR2 only gives the maintenance message LOCALIZER ANTENNA (3RT)/COAX CABLE/MMR2(40RT2):
- swap the MMR-1 (40RT1) and the MMR-2 (40RT2) (Ref. AMM TASK 34-36-31-000-002) and (Ref. AMM TASK 34-36-31-400-002)
- do the BITE test of the MMR2 (Ref. AMM TASK 34-36-00-740-003).
(1) If the test of the MMR2 gives the maintenance message LOCALIZER ANTENNA (3RT)/COAX CABLE/MMR2(40RT2):
- remove the MMR2
- remove the localizer antenna 1/2 (Ref. AMM TASK 34-36-11-000-001)
- make sure that there is continuity on the coaxial cable between the MMR2 and the localizer antenna 1/2 (3RT) (Ref. ASM 34-36/01)
- replace the coaxial cable if necessary
- make sure that there is discontinuity between the core and the shield of the coaxial cable
- repair if necessary
- install the MMR2
- install the localizer antenna 1/2 (3RT) (Ref. AMM TASK 34-36-11-400-001).
