B. If there is no identification signal on the loud speakers with the circuit breaker (1RT1) open:
- replace the RECEIVER-ILS, 2 (2RT2) (Ref. AMM TASK 34-36-31-000-001) and (Ref. AMM TASK 34-36-31-400-001).
(1) If the fault continues:
- replace the AMU (1RN) (Ref. AMM TASK 23-51-34-000-001) and (Ref. AMM TASK 23-51-34-400-001).
(2) If the fault continues:
- do a check and repair the wiring of the AUDIO OUTPUT bus from the ILS receiver 2 (2RT2) to the AMU (1RN) (Ref. ASM 34-36/01).

A. Test
(1) Do the BITE test of the ILS (system 1) (Ref. AMM TASK 34-36-00-740-002).
4. Fault Isolation
_______________
A. If the test gives the maintenance message LGCIU1(5GA1)/FMGEC1(1CA1)/ILS1 (1RT1):
- do a check for a short to ground at pins AB/15D, 1C of the RECEIVER-ILS, 1 (2RT1) (Ref. ASM 34-36/01).
