(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 L windshield (3DG1) 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 30-42-01) and (Ref. ASM 30-42/01),
- disconnect the wiring from pin A/D and connect it to pin A/F (Ref. AWM 30-42-01) and (Ref. ASM 30-42/01).

- 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 30-42-01) and (Ref. ASM 30-42/01),
- disconnect the wiring from pin A/C (or A/E) and connect it to pin A/D (Ref. AWM 30-42-01) and (Ref. ASM 30-42/01).

than 370 ohms:
- replace the WINDSHIELD-L (3DG1), (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 30-42-01) and (Ref. ASM 30-42/01).
3 If the fault continues:
_
- replace the WHC-1 (2DG1), (Ref. AMM TASK 30-42-34-000-001) and (Ref. AMM TASK 30-42-34-400-001).
4 If the fault continues:
_
- do a check and repair the wiring from the WHC 1 (2DG1) to the L windshield (3DG1) pin B/A and pin B/B to pins A/C and A/D, 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-1 (2DG1), (Ref. AMM TASK 30-42-34-000-001) and
_ (Ref. AMM TASK 30-42-34-400-001).
2 If the fault continues:
