A. If the test gives the maintenance message WRG: ACFT TYPE PIN PROG/ ADIRU1 (1FP1):
Subtask 34-13-00-810-200-B ** ON A/C NOT FOR ALL - remove the ADIRU-1 [1FP1] AMM 34-12-34-000-001
- do a check of the aircraft identification-code programming-pins AA/1E, 1F, 1G, 1H, 1J, 1K, 2E, 4A, on the rack connector
- compare the state of the aircraft identification-code pin-programming with the state given in the ASM ASM 341141.
- repair the defective wiring of the rack connector
- install the ADIRU1 AMM 34-12-34-400-001.
- install a new ADIRU1.
