- do a check of the wiring and make sure that there is a ground signal at pin AA/7G and an open circuit at pin AA/7F on the rack connector.
(1) If the pin programming is incorrect:
- repair the aircraft wiring: defective pin
- install the ADIRU2.
(2) If the pin programming is correct:
- do a check of pin AA/3C on the rack connector
- compare the state of the pin with the BARO PORT A SELECT pin programming given in the ASM (Ref. ASM 34-12/02).
(a) If the pin programming is correct:
- install a new ADIRU2 (Ref. AMM TASK 34-12-34-400-001).
