 B. If the test gives the maintenance message R WINDSHIELD SENSOR associated with ECAM message ANTI-ICE R WINDSHIELD, or ANTI-ICE R WINDOW:
 (1) 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 selected off:

 - select air conditioning PACK on,

 - after 5 minutes, open and close C/B 5DG2 to reset WHC2.

 

 (2) If the fault continues:


 - disconnect the connector from the R windshield (3DG2) and do a check of the resistance between pins A/C and A/D. (Ref. Fig. 202/TASK 30-42-00-991-007, 204/TASK 30-42-00-991-002)
 (a) If the resistance is more than 715 ohms (open circuit) or less than 370 ohms (short circuit):
 NOTE : If only one sensor is available we recommend the
____ replacement of the WINDSHIELD-R (3DG2) if you operate in icing conditions.
 - do a check of the resistance of the sensor 2 between pins A/E and A/F for correct value. (Ref. Fig. 202/TASK 30-42-00-991-007)
 1 If the resistance of the sensor 2 is between 370 ohms and 715
_
 ohms:

 - disconnect the wiring from pin A/C and connect it to pin A/E (Ref. AWM 30-42-02) and (Ref. ASM 30-42/02),

 - disconnect the wiring from pin A/D and connect it to pin A/F (Ref. AWM 30-42-02) and (Ref. ASM 30-42/02).


 2 If the resistance of the sensor 2 is more than 715 ohms or
_ less than 370 ohms and if a third sensor is installed in the windshield (in relation with the part number):
 - do a check of the resistance of the sensor 3 between pins A/D and A/E for correct value. (Ref. Fig. 202/TASK 30-42-00-991-007)
 a If the resistance of the sensor 3 is between 370 ohms and
_
 715 ohms:

 - disconnect the wiring from pin A/D (or A/F) and connect it to pin A/E (Ref. AWM 30-42-02) and (Ref. ASM 30-42/02),

 - disconnect the wiring from pin A/C (or A/E) and connect it to pin A/D (Ref. AWM 30-42-02) and (Ref. ASM 30-42/02).


 b If the sensor 3 resistance is more than 715 ohms or less
_
 than 370 ohms:

 - replace the WINDSHIELD-R (3DG2), (Ref. AMM TASK 56-11-11-000-001) and (Ref. AMM TASK 56-11-11-400-001).

 - put the wiring back to its serviceable configuration (Ref. AWM 30-42-02) and (Ref. ASM 30-42/02).


 c If the fault continues:
_
 - replace the WHC-2 (2DG2), (Ref. AMM TASK 30-42-34-000-001) and (Ref. AMM TASK 30-42-34-400-001).
 3 If the fault continues:
_
 - do a check and repair the wiring from the WHC 2 (2DG2) to the R windshield (3DG2) pins B/A and B/B to pins A/C and A/D and pins B/A and B/B to pins A/E and A/F and pins B/A and B/B to pins A/D and A/E.
 (b) If the resistance is between 370 ohms and 715 ohms:
 1 replace the WHC-2 (2DG2), (Ref. AMM TASK 30-42-34-000-001) and
_ (Ref. AMM TASK 30-42-34-400-001).
 2 If the fault continues:
_
 - do a check and repair the wiring from the WHC 2 (2DG2) to the R windshield (3DG2) pins B/A and B/B to pins A/C and A/D and pins B/A and B/B to pins A/E and A/F and pins B/A and B/B to pins A/D and A/E.

 B. If the test gives the maintenance message R WINDSHIELD SENSOR:
 - disconnect the connector from the R windshield (3DG2) and do a check of the resistance between pins A/C and A/D. (Ref. Fig. 202/TASK 30-42-00-991-007, 204/TASK 30-42-00-991-002)

 (a) If the resistance of the sensor 3 is between 370 ohms and 715 ohms:
 - connect pins B/A and B/B of the WHC2 (2DG2) to pins A/D and A/E R of the sensor 3 (Ref. ESPM 20-44-11) and (Ref. ASM 30-42/02).
