B. If the test shows that there are no GPS 1 (GPS 2) data on the MCDU GPS MONITOR Page and that dashes are shown:
(1) Do a check for a maintenance message related to the GPSSU 1 (GPSSU2) or MMR 1 (MMR 2) on the POST FLIGHT REPORT (PFR):
(a) If there is no maintenance message:
- do a reset of the MMR 1 (MMR 2) circuit breaker 42RT1 (42RT2).
(b) If there is a maintenance message:
- you can find the related trouble shooting procedure in the applicable Page Block 101.
C. Do the test given in Para. 3.A.

__________________
A. Test
(1) Do the Interface test of the IR (system 1) (Ref. AMM TASK 34-14-00-740-001)
4. Fault Isolation
_______________
A. If the test gives the maintenance message MMR1-GPSSU1(40RT1-1SN1)/
ADIRU1(1FP1):
NOTE : In this case the GPSSU1 message is for the GPS part of the MMR1.
____
- replace the MMR-1 (40RT1) (Ref. AMM TASK 34-36-31-000-002) and (Ref. AMM TASK 34-36-31-400-002).

CES (1) If the fault continues:
- replace the ADIRU-1 (1FP1) (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 MMR1 to the ADIRU1: 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).
B. Do the test given in para. 3.
