B. If the tests give these three maintenance messages
RMP1(1RG1)
RMP1(1RG1)/RMP2(1RG2)
RMP1(1RG1)/RMP3(1RG3):
- do a check of the circuit breaker (2RG1) status.
(1) If the circuit breaker (2RG1) is closed:
- do a check for 28VDC at pin A/N of the RMP 1 (1RG1) (Ref. ASM 23-13/01).
(a) If there is 28VDC:
- replace the RMP-COM/NAV FREQ SEL, 1 (1RG1) (Ref. AMM TASK 23-13-13-000-001) and (Ref. AMM TASK 23-13-13-400-001).
(b) If there is no 28VDC:
- do a check for a ground signal at pin A/R of the RMP 1 (1RG1) (Ref. ASM 23-13/01).
1 If there is no ground signal:
_
- repair the wiring between the RMP 1 (1RG1) pin A/R and the ground terminal (Ref. ASM 23-13/01).
2 If there is a ground signal:
_
- do a check of the wiring between the RMP 1 (1RG1) pin A/N and the circuit breaker (2RG1) (Ref. ASM 23-13/01).
a If there is no continuity:
_ - repair the above wiring.
b If there is continuity:
_
- replace the circuit breaker (2RG1).
(2) If the circuit breaker (2RG1) is open:
- close it.
(a) If it opens again:
- replace the RMP 1 (1RG1) (Ref. AMM TASK 23-13-13-000-001) and (Ref. AMM TASK 23-13-13-400-001).
1 If the fault continues:
_
- do a check for a short to ground at the wiring between the RMP 1 (1RG1) pin A/N and the circuit breaker (2RG1) (Ref. ASM 23-13/01).

R a_ If there is a short to ground:
R - repair the related wiring.
R b_ If there is no short to ground:
R - replace the C/B-COM/RMP/1 (2RG1).
R (b) If the circuit breaker stays closed and the fault continues:
R - replace the RMP 1 (1RG1) (Ref. AMM TASK 23-13-13-000-001) and
