Initialization of the rain sensor
To ensure that the optical measuring procedure for the detection of precipitation functions properly, the rain sensor must be adapted to the windscreen.
A prerequisite for trouble-free initialization is that the windscreen glass is dry, clean and free of defects in the area of the rain sensor.
The initialization is performed using the "Initialize rain sensor" service function in the diagnosis system. This service function updates the adaptation values in the rain sensor.
A re-initialization of the rain sensor is required:
- After replacing the windscreen
- After replacement of a rain-light-solar-condensation sensor
