A. If the test gives the maintenance message WRG:AOA AVERAGE-UNIQUE PIN PROG:
Subtask 34-13-00-740-332-A ** ON A/C NOT FOR ALL - Remove ADIRU2 AMM 34-12-34-000-001.
- Do a check of pin AA/5K on the rack connector.
- Compare the status of the pin with the AOA average-unique pin-programming given in ASM 341202.
- Install a new ADIRU-2 [1FP2] AMM 34-12-34-400-001.
- Repair the wiring of the AOA average-unique pin-programming of ADIRU2 : pin AA/5K.
- Install ADIRU2 AMM 34-12-34-400-001.
B. Do the test given in Para. 3.
