__________________
A. Test
(1) Do the Interface test of the IR (system 2) (Ref. AMM TASK 34-14-00-740-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message MMR2-GPSSU2(40RT2-1SN2)/ADIRU2 (1FP2):
NOTE : In this case the GPSSU2 message is for the GPS part of the MMR2.
____
- replace the MMR-2 (40RT2) (Ref. AMM TASK 34-36-31-000-002) and (Ref. AMM TASK 34-36-31-400-002).
(1) If the fault continues:
- replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring from the MMR2 to the ADIRU2: pins AB/2C, 2D to pins AB/14D, 15D for the GNSS INPUT 1 DATA bus and pins AB/2A, 2B to pins AB/14J, 15J for the GNSS INPUT 1 TIME MARK bus (Ref. ASM 34-36/02).
