Rain Sensor: Testing and Inspection
Diagnosis Procedure
RAIN SENSOR
Diagnosis Procedure
1.CHECK RAIN SENSOR FUSE
1. Turn the ignition switch OFF.
2. Check that the rain sensor 10 A fuse (#6) is not fusing.
Is the fuse fusing?
YES - Replace the fuse after repairing the applicable circuit.
NO - GO TO 2.
2.CHECK RAIN SENSOR POWER SUPPLY
1. Disconnect rain sensor connector.
2. Check voltage between rain sensor harness connector and ground.
Is the measurement value normal?
YES - GO TO 3.
NO - Repair or replace harness.
3.CHECK RAIN SENSOR GROUND CIRCUIT
Check continuity between rain sensor harness connector and ground.
Does continuity exist?
YES - GO TO 4.
NO - Repair or replace harness.
4.CHECK RAIN SENSOR SIGNAL
1. Connect rain sensor connector.
2. Turn ignition switch ON.
3. Check signal between BCM harness connector and ground with oscilloscope.
Is the measurement value normal?
YES - Replace rain sensor.
NO - GO TO 5.
5.CHECK RAIN SENSOR SIGNAL CIRCUIT FOR OPEN
1. Disconnect BCM connector and rain sensor connector.
2. Check continuity between BCM harness connector and rain sensor harness connector.
