 A. If the BITE test gives the maintenance message RMP1/2/3 (1RG1/2/3)/HF1 (3RE1):
 - 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).
 (1) If the fault continues:
 - do a check and repair the wiring of the COM 1 DATA OUTPUT signal (from RMP 1 (1RG1) pins A/p, q to the first terminal block) (Ref. ASM 23-13/02).
