 **ON A/C ALL

 A. If the test gives the maintenance message:
 FWC 2 : PIN PROGRAM FAIL

 (1) Read the pin programming related to the FWC 2 (Ref. AMM TASK 31-50-00-740-002).

 (2) Compare the pin programming related to the FWC 2 with the state of the aircraft pin programming given in the ASM (Ref. ASM 31-52/01).

 (a) If the pin programming is incorrect:

 - reapir the aircraft wiring.

 (b) If the pin programming is correct:

 - replace the FWC-2 (1WW2), (Ref. AMM TASK 31-53-34-000-001) and (Ref. AMM TASK 31-53-34-400-001).
