A. If the test gives the maintenance message WRG:ACFT TYPE PIN PROG/ADIRU3 (1FP3):
Subtask 34-14-00-740-244-A - do a check of the A/C IDENT CODE pin-programming pins AA/1E, 1F, 1G, 1H, 1J, 1K, 2E on the rack connector,
- compare the status of the A/C IDENT CODE pin-programming with the status given in the ASM ASM 341203.
- repair the wiring of the defective programming pins ASM 341203.
- replace the ADIRU-3 [1FP3] AMM 34-12-34-000-001 and AMM 34-12-34-400-001.
B. Do the test given in Para. 3.
