- make sure that there is continuity on the coaxial cable between the MMR1 and the glide antenna 1/2 (4RT) (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 glide antenna 1/2 (4RT) (Ref. AMM TASK 34-36-18-400-001).
(2) If the test of the MMR1 does not give the maintenance message GLIDE ANTENNA (4RT)/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
GLIDE ANTENNA (4RT)/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 GLIDE ANTENNA (4RT)/COAX CABLE/MMR2(40RT2):
- remove the MMR2
- remove the glide antenna 1/2 (Ref. AMM TASK 34-36-18-000-001)
- make sure that there is continuity on the coaxial cable between the MMR2 and the glide antenna 1/2 (4RT) (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 glide antenna 1/2 (4RT) (Ref. AMM TASK 34-36-18-400-001).

(2) If the test of the MMR2 does not give the maintenance message
GLIDE ANTENNA (4RT)/COAX CABLE/MMR2(40RT2):
- replace the MMR that you installed on side 1.
C. If the test of the MMR1 gives the maintenance message GLIDE ANTENNA (4RT)/COAX CABLE/MMR1(40RT1) and if the test of the MMR2 gives the maintenance message GLIDE ANTENNA (4RT)/COAX CABLE/MMR2(40RT2):
- replace the ANTENNA-GLIDE/SLOPE 1/2 (4RT) (Ref. AMM TASK 34-36-11-000-001) and (Ref. AMM TASK 34-36-11-400-001).
D. Do the test given in Para. 3.

R R R R R R A. If the test gives the maintenance message GPS ANTENNA1(43RT1)/COAX CABLE/MMR1(40RT1): - remove the MMR1 (Ref. AMM TASK 34-36-31-000-002) - remove the GPS antenna 1 (Ref. AMM TASK 34-36-16-000-001) - make sure that there is no moisture and/or corrosion on the coaxial cable of the GPS antenna 1 - if you find corrosion damage, refer to the Structural Repair Manual (Ref. SRM 517400 P.Block001) for types, inspection, removal and corrosion protection. - make sure that there is continuity on the coaxial cable of the GPS antenna 1 (Ref. AMM TASK 20-28-00-912-003) - replace the coaxial cable if necessary - make sure that there is discontinuity between the core and shield of the coaxial cable of the GPS antenna 1 - repair if necessary.
(1) If the fault stops: - install the MMR1 (Ref. AMM TASK 34-36-31-400-002) - install the GPS antenna 1 (Ref. AMM TASK 34-36-16-400-001).
(2) If the fault continues: - install a new ANTENNA-GPS ACTIVE, 1 (43RT1) (Ref. AMM TASK 34-36-16-400-001) - install the MMR1 (Ref. AMM TASK 34-36-31-400-002).
