R
 A. Test
 (1) Do the Interface test of the IR (system 2) (Ref. AMM TASK 34-14-00-740-001).

R

 4. Fault Isolation_______________ 
R  A. If the test gives the maintenance message GPSSU1 (1SN1)/ADIRU2 (1FP2): 
R  - replace the GPSSU-1 (1SN1) (Ref. AMM TASK 34-58-31-000-001) and (Ref. 
R  AMM TASK 34-58-31-400-001). 
R  (1) If the fault continues: 
R  - replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and 
R  (Ref. AMM TASK 34-12-34-400-001). 
R  (a) If the fault continues: 
R  - do a check and repair the wiring from the GPSSU1 to the ADIRU2: 
R  pins A/24, 25 to pins AB/7C, 8C for the SECONDARY GPS DATA IN 
R  bus and pins A/9, 22 to pins AB/1C, 2C for the SECONDARY GPS 
R  TIME MARK bus (Ref. ASM 34-58/01).
 B. Do the test given in para. 3.
