Inability to know the SDI Code Related to the ADM1 and the ADM5

1. Possible Causes

2. Job Set-up Information
A. Referenced Information

REFERENCE	DESIGNATION
AMM 34-11-17-000-001	Removal of the Air Data Module
AMM 34-11-17-400-001	Installation of the Air Data Module
AMM 34-13-00-740-002	INTERFACE TEST of the ADR
ASM 341303

3. Fault Confirmation
Subtask 34-11-00-740-128-A

A. Test
Do the Interface test of the ADR (system 1) AMM 34-13-00-740-002.

4. Fault Isolation
Subtask 34-11-00-810-201-A

A. If the test gives the maintenance message ADM1 (19FP1)/ ADM5 (19FP5):

get access to the total pressure ADM1 (19FP1) AMM 34-11-17-000-001 (Para. 2.B.)
disconnect the electrical connector of the ADM (19FP1)
make sure that there is continuity between pins A/J, K and that there is an open circuit between pins A/L, M, N, P ASM 341303.

(1) If the pin programming is incorrect:

(2) If the pin programming is correct:

get access to the L static pressure ADM (19FP5) AMM 34-11-17-000-001 (Para. 2.B.)
disconnect the electrical connector of the ADM (19FP5)
make sure that there is continuity between pins A/J, K, M, P and that there is an open circuit between pins A/L, N.

(a) If the pin programming is incorrect:

(b) If the pin programming is correct:

replace the ADM-L TOTAL PRESSURE [19FP1] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
connect the electrical connector of the ADM (19FP5).

1 If the fault continues:

Subtask 34-11-00-740-129-A

B. Do the test given in Para. 3.
