Functional Checks Rain\-\-\> Steering column switch is in auto mode \(sensor is active\) it is necessary to splash water on the sensitive surface of the sensor to trigger wipes. check the same for different sensitivities When the rain sensitivity is increased \(for example from level 0 to level 1\), as an acknowledgement a single wipe is seen. \(This is not a phantom wipe\) and this single wipe is not seen when the rain sensitivity is decreased \(from higher level to lower level\) Light\-\-\> Steering column switch is in auto mode \(sensor is active\) block the light coming on the sensor from outside of the vehicle \(use a opaque object\), the head lamps should be activated 3. If the sensor seems functional, it is ideal to remove the silicon gel pad from the sensor, replace it with the new silicon gel pad instead of replacing the whole sensor. When servicing the LRSM please replace the silicon gel pad with a new silicon gel pad \(PN 68224945AA\) instead of replacing the whole sensor.
