(c) Do the test in para 3.A. with the L/G simulated to shock absorbers extended (Ref. AMM TASK 32-69-00-860-001).
(2) If the test in para. 3.A. is not OK:
(a) Do a check to see if the circuit breaker (2DL) is open, if it is open, do (Ref. TASK 30-11-00-810-809).
(3) If the circuit breaker (2DL) is closed:
(a) On the P/BSW (3DL) connector do a check for 28VDC on the pin D1 (Ref. ASM 30-11/01).
(b) If there is no 28VDC, replace the C/B-ANTI-ICE/WING/CTL 2DL.
(c) Do the test in Para. 3.A.
(4) If there is 28VDC:
(a) With the P/BSW 3DL connected, and set to on, do a check for 28VDC at the relay anti-ice valve control, connector pin X (Ref. ASM 30-11/01).
(b) If there is no 28VDC, replace the P/BSW ANTI ICE/WING 3DL.
(c) Do the test in para. 3.A.
(5) If there is 28VDC:
(a) Replace the RELAY ANTI ICE VALVE CONTROL 5DL
(b) Do the test in Para. 3.A.
(6) If the fault continues:
(a) Replace the RELAY GROUND TEST (4DL).
(b) Do the test in Para. 3.A.
(7) If the fault continues:
(a) Do a check of the aircraft wiring (Ref. ASM 30-11/01) between:
- the circuit breaker (2DL) and the P/BSW (3DL)
- relay (3DL) and relay (5DL)
- relay (5DL) and relay (4DL)
- relay (4DL) connector pin A3 and pin X2 for ground
(b) Repair all the unserviceable wiring and connectors.
(c) Do the test in Para. 3.A.

Wing Anti-Ice - Spurious Fault Indications.
1. Possible Causes_______________
- Wing Anti-Ice System
2. Job Set-up Information______________________ Not Applicable
3. Fault Confirmation__________________
A. Test
(1) Examine the ECAM display for the Wing Anti-Ice System fault warning.
4. Fault Isolation_______________
A. Procedure
(1) If the ECAM shows the Wing Anti-Ice System warning, do the trouble shooting procedure related to the maintenance message.
(2) If the ECAM shows no Wing Anti-Ice System warning, the CFDS message can be regarded as spurious and requires no further action.

A. Procedure
CAUTION : MAKE SURE THAT YOU SET THE WING ANTI-ICE SYSTEM P/BSW TO OFF
_______ AFTER 30 SECONDS. THIS WILL PREVENT DAMAGE TO THE SLATS.
NOTE : When the Wing Anti-Ice System Ground Test is OK, the system will
____ automatically switch off after 30 seconds. If after 35 seconds the anti-ice symbols on the BLEED page, on the lower ECAM DU, do not go off, the ANTI ICE WING P/BSW must be released (out) manually.
