- 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 gives the maintenance message
FMGC1(1CA1) BUS GPS/MMR2(40RT2):
- replace the MMR that you installed on the side 2.
(2) If the fault continues:
- replace the FMGC-2 (1CA2) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring from the FMGC2 to the MMR1 from pins AB/10A, 10B to pins AB/8J, 8K (Ref. ASM 34-36/02).
B. Do the test given in para. 3.
