33 Body Electrical System Rain Sensor – Europe, North America (option) In ignition switch is on state, if AUTO switch, multi function switch, is on then wiper is controlled by the rain sensor signal. Diagnosis Step 1 1. With ignition on, move the multi function switch to Auto position. 2. Rotate the intermittent volume switch. (5th to 4th speed) 3. If a wipe occurs, then Fault A has been detected - Check coupler area on the windscreen is not damaged. - Check the sensor is secured to the coupler. Step 2 4. Rotate intermittent volume switch one more setting.(4th to 3th speed) 5. If a wipe occurs, then Fault B has been detected. - Sensor should be removed and replaced with a known good sensor.
