- connect pins B/W and B/X of the WHC2 (2DG2) to pins A/E and A/F of the spare sensor (Ref. AWM 30-42-04) and (Ref. ASM 30-42/02).
(b) If the resistance of the spare sensor is more than 715 ohms or less than 370 ohms:
- replace the WINDOW-SLIDING, R (8DG2), (Ref. AMM TASK 56-12-11-000-001) and (Ref. AMM TASK 56-12-11-400-001).
(c) If the fault continues:
- replace the WHC-2 (2DG2), (Ref. AMM TASK 30-42-34-000-001) (Ref. AMM TASK 30-42-34-400-001).
(d) If the fault continues:
- do a check and repair the wiring from the WHC2 (2DG2) to the R sliding window (8DG2) pins B/W and B/X to pins A/D and A/C and pins B/W and B/X to pins A/E and A/F.
(2) If the resistance is between 370 ohms and 715 ohms:
- replace the WHC-2 (2DG2), (Ref. AMM TASK 30-42-34-000-001) and (Ref. AMM TASK 30-42-34-400-001).
(a) If the fault continues:
- do a check and repair the wiring from the WHC2 (2DG2) to the R sliding window (8DG2) pins B/W and B/X to pins A/D and A/C and pins B/W and B/X to pins A/E and A/F.

A. Test
(1) Do the operational test of the windshield anti-icing and defogging (Ref. AMM TASK 30-42-00-710-001).
4. Fault Isolation

B. If the test gives the maintenance message R FIXED WINDOW SENSOR associated with ECAM message ANTI-ICE R WINDSHIELD, or ANTI-ICE R WINDOW:
(1) If the WHC2 PN 6664287 is installed and if the ECAM warning is triggered on ground with OAT greater than 40 deg.C or if the cockpit window/windshield is directly heading to the sun and air conditioning packs off: - operate the air conditioning packs
- after 5 minutes, open and close circuit breaker 5DG2 to do a reset of the WHC2.
(a) If the fault continues:
- refer to Para. C.
(2) If the WHC2 PN 6664287 is not installed:
- refer to Para. C.
**ON A/C 215-220, 224-224,
C. If the test gives the maintenance message R FIXED WINDOW SENSOR:
- disconnect the connector from the R fixed window (7DG2) and do a check of the resistance between pin A/C and pin A/D. (Ref. Fig. 210/TASK 30-42-00-991-006)
(1) If the resistance is more than 715 ohms (open circuit) (OAT more than 40 deg. C) or less than 370 ohms (short circuit):
- do a check of the resistance of the spare sensor between pins A/E and A/F for correct value.
