Nissan Juke Service and Repair Manual : Light & rain sensor
Component Function Check
1.CHECK FRONT WIPER AUTO OPERATION
1. Clean rain sensor detection area of windshield fully.
2. When the front wiper switch is turned to AUTO position, front wiper operates once regardless of a rainy condition.
Is front wiper (AUTO) operation normally? YES >> Rain sensor circuit is normal.
NO >> Refer to WW-42, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK LIGHT & RAIN SENSOR FUSE
1. Turn the ignition switch OFF.
2. Check that the light & rain sensor 10A fuse (#7) is not fusing.
Is the fuse fusing? YES >> Replace the fuse after repairing the applicable circuit.
NO >> GO TO 2.
2.CHECK LIGHT & RAIN SENSOR POWER SUPPLY
1. Disconnect light & rain sensor connector.
2. Check voltage between light & rain sensor harness connector and ground.
Is the insepection result normal? YES >> GO TO 3.
NO >> Repair or replace harness.
3.CHECK LIGHT & RAIN SENSOR GROUND CIRCUIT
Check continuity between light & rain sensor harness connector and ground.
Is the insepection result normal? YES >> GO TO 4.
NO >> Repair or replace harness.
4.CHECK LIGHT & RAIN SENSOR SIGNAL
1. Connect light & rain sensor connector.
2. Turn ignition switch ON.
3. Check signal between BCM harness connector and ground with oscilloscope.
Is the insepection result normal? YES >> Replace light & rain sensor.
NO >> GO TO 5.
5.CHECK LIGHT & RAIN SENSOR SIGNAL CIRCUIT FOR OPEN
1. Turn ignition switch OFF.
2. Disconnect BCM connector and light & rain sensor connector.
3. Check continuity between BCM harness connector and light & rain sensor harness connector.
Is the insepection result normal? YES >> GO TO 6.
NO >> Repair or replace harness.
6.CHECK LIGHT & RAIN SENSOR SIGNAL CIRCUIT FOR SHORT
Check continuity between BCM harness connector and ground.
Is the insepection result normal? YES >> Repair or replace harness.
NO >> Replace BCM. Refer to BCS-93, "Removal and Installation" (with Intelligent Key system) or BCS- 161, "Removal and Installation" (Without Intelligent Key system).
