Inability to know the SDI Code Related to the ADM2 and the ADM7

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 34-11-00-740-130-A

A. Test
Do the Interface test of the ADR (system 2) AMM 34-13-00-740-002.

4. Fault Isolation
Subtask 34-11-00-810-202-A

A. If the test gives the maintenance message ADM2 (19FP2)/ ADM7 (19FP7):

get access to the total pressure ADM (19FP2) AMM 34-11-17-000-001 (Para. 2.B.)
disconnect the electrical connector of the ADM (19FP2)
make sure that there is continuity between pins A/J, L and that there is an open circuit between pins A/K ,M ,N ,P ASM 341303.

(1) If the pin programming is incorrect:

(2) If the pin programming is correct:

get access to the ADM (19FP7) AMM 34-11-17-000-001 (Para. 2.B.)
disconnect the electrical connector of the ADM (19FP7)
make sure that there is continuity between pins A/J, L, M, P and that there is an open circuit between pins A/K, N.

(a) If the pin programming is incorrect:

(b) If the pin programming is correct:

replace the ADM-R TOTAL PRESSURE [19FP2] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
connect the electrical connector of the ADM (19FP7).

1 If the fault continues:

Subtask 34-11-00-740-131-A

B. Do the test given in Para. 3.
