REFERENCE	DESIGNATION
TSM TASK 27-81-00-810-833-A	Slats - Pin Program Disagree Installation Fault
ASM 275108
AMM 27-51-34-000-001	Removal of the SFCC
AMM 27-51-34-400-001	Installation of the SFCC
AMM 31-32-00-860-006	Procedure to Get Access to the SYSTEM REPORT/TEST F/CTL Page

3. Fault Confirmation
Subtask 27-51-00-740-073-A

A. Test
(1) Get access to the SYSTEM REPORT/TEST F/CTL page, AMM 31-32-00-860-006, press the line key for the applicable SFCC menu, and press the line key for FLP class 3 faults.
(2) If you can get access to the SFCC menu, and FLP class 3 faults, the fault has gone. The system is also serviceable if "PIN PROGRAM DISAGREE INSTALLATION" is shown in class 3 faults, no further action is required. The fault has gone but it has been recorded.
(3) If you cannot get access to the SFCC menu, do the fault isolation procedure.

4. Fault Isolation
Subtask 27-51-00-810-098-A

A. Procedure
(1) If the message "pin prog disagree" is shown, go to Para. (3).
(2) If the message "pin prog disagree flp" is shown, go to Para. (4).

NOTE: If the message "pin prog disagree slt" is shown, go to the procedure (Ref. TSM TASK 27-81-00-810-833).

NOTE: During this procedure when you interchange, remove or install an SFCC, the AMM procedures AMM 27-51-34-000-001 and AMM 27-51-34-400-001 must be used.

(3) If you cannot get access to the SFCC menu and the message "pin prog disagree" is shown:
(a) Interchange the SFCC's and try to access the SFCC menu of the two SFCC's, Ref. Para. 3. A. (1).
(b) If the fault moves to the other SFCC position:
1 Put the serviceable SFCC back in its initial position.
2 Replace the SLAT/FLAP CONTR.COMP. [21CV] or SLAT/FLAP CONTR.COMP. [22CV] that has the fault.
3 Do the test in Para. 3. A. (1).
(c) If the fault does not move to the other SFCC position:
1 Put the SFCC's back in their initial position.
2 Do a check of the aircraft wiring at the SFCC flap channel ASM 275108.
3 Repair any defect found.
4 Do the test in Para. 3. A. (1).
(4) If the message "pin prog disagree flp" is shown:
(a) Interchange the SFCC's.
(b) Do the test in Para. 3. A. (1).
(c) If the fault moves to the other SFCC position:
1 Put the serviceable SFCC back in its initial position.
2 Replace the SFCC that has the fault.
3 Do the test in Para. 3. A. (1).
(d) If the fault does not move to the other SFCC position:
1 Put the SFCC's back in their initial position.
2 Do a check of the aircraft wiring, Ref. Para. (3) (c)2_.
3 Repair any defect found.
4 Do the test in Para. 3. A. (1).
