Failure of the ADR 1 or ADM SDI Pin-Programming
1. Possible Causes
- wiring of the defective programming-pins
- ADM-L TOTAL PRESSURE [19FP1]
- wiring of the defective pins
- ADM-L STATIC PRESSURE [19FP5]

A. If the test gives the maintenance message ADIRU 1 or PROG PIN or ADM 19FP1 or ADM 19FP5:
Subtask 34-13-00-740-369-A ** ON A/C NOT FOR ALL - do a check of SDI programming-pins AA/1A, 5A, 6A on the rack connector
- compare the state of the pins with the SDI pin-programming given in the ASM ASM 341201.
- repair the wiring of the defective programming-pins ASM 341201.
- swap the ADIRU 1 and the ADIRU 2 AMM 34-12-34-000-001 and AMM 34-12-34-400-001.
- replace the ADIRU that you installed on side 2.
- get access to the ADM-L TOTAL PRESSURE [19FP1] AMM 34-11-17-000-001
- disconnect the electrical connector of the L total pressure ADM (19FP1)
- make sure that there is continuity between pins A/J and K and that there is an open circuit between pins A/L, M, N and P.
- repair the wiring of the defective pins ASM 341303
- connect the electrical connector of the L total pressure ADM (19FP1).
- get access to the ADM-L STATIC PRESSURE [19FP5] AMM 34-11-17-000-001
- disconnect the electrical connector of the L static pressure ADM (19FP5)
- make sure that there is continuity between pins A/J, K, M and P and that there is an open circuit between pins A/L and N.
- repair the wiring of the defective pins ASM 341303
- connect the electrical connector of the L static pressure ADM (19FP5).
- replace the L total pressure ADM (19FP1) AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
. If the fault continues:
- replace the L static pressure ADM (19FP5) AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
B. Do the test given in Para. 3.
