C. Test
(1) Do the BITE test of the EFCS (Ground Scanning) (Ref. AMM TASK 27-96-00-740-001).
4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message:
G HYD PRESS SW1
- do the trouble shooting procedure (Ref. TASK 31-32-00-810-932) . related to the DSI 17 discret input signal of the SEC 1, . related to the DSI 42 discret input signal of the ELAC 1 COM and ELAC 2 COM (Ref. ASM 27-92/27)
- open and close the circuit breakers 20CE1 and 20CE2.
(1) If the fault continues:
- replace the PRESS SW-FLT CTL, G (1151GN), (Ref. AMM TASK 29-32-12-
000-001) and (Ref. AMM TASK 29-32-12-400-001). - open and close the circuit breakers 20CE1 and 20CE2.
(a) If the fault continues:
- do a check and repair the wiring from the pressure switch (1151GN) pin A/B to the first terminal block, (Ref. ASM 27-92/27).
- open and close the circuit breakers 20CE1 and 20CE2.
B. Do the BITE test given in Para. 3.
5. Close-up
________
A. Depressurize the Green hydraulic system (Ref. AMM TASK 29-10-00-864-001).
