A. Test
(1) Do the operational test of the probe ice protection (Ref. AMM TASK 30-31-00-710-001).
4. Fault Isolation
_______________
A. If the test gives the maintenance message PITOT PROBE 9DA1:
- disconnect the connector from the pitot probe 1 (9DA1) and do a check of the resistance between pins A/B and A/C.
(1) If the resistance is more than 43 ohms (open circuit) or less than 35 ohms (short circuit):
(a) Replace the PROBE-PITOT, 1 (9DA1) (Ref. AMM TASK 34-11-15-000-001) and (Ref. AMM TASK 34-11-15-400-001).
(2) If the resistance is between 35 ohms and 43 ohms:
(a) Replace the PHC-1 (6DA1) (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).

Feb 01/98 CES (b) If the fault continues:
- do a check and repair the wiring from the PHC 1 (6DA1) to the pitot probe 1 (9DA1), pin A/H to pin A/B (Ref. ASM 30-31/01).
B. Do the operational test given in Para. 3.

R A. If the ECAM warning message ANTI ICE CAPT PITOT comes into view only or R associated with the maintenance message CHECK LGCIU - PHC1 INTERFACE and R if the loss of the GND/FLT information occurred:
- make sure that there is no maintenance message related to the landing gear system (Ref. ATA 32).
(1) If there is one or more maintenance message(s):
- do the related trouble shooting.
(2) If there is no maintenance message:
- do the inspection of the MLG proximity sensor and target clearances (Ref. AMM TASK 32-31-73-200-001).
(a) If the fault continues:
- replace the PROX SNSR-L L/G EXT, SYS 1 (21GA) and PROX SNSR-L L/G EXT, SYS 2 (23GA) , (Ref. AMM TASK 32-31-73-000-001) and (Ref. AMM TASK 32-31-73-400-001).
(b) If the fault continues:
- do a check for ground signal at pin A/E and/or pin A/D and/or pin A/I of the PHC1 (6DA1).
1 If there is no ground signal:
_
- replace the LGCIU-1 (5GA1) (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
2 If there is a ground signal:
_ Simulate the flight configuration: - on the panel 49VU, open the L/G/LGCIU/SYS1/NORM (1GA)
