Safety function in the event of failure (motor block)

NOTE:
- Two types of motor block can be distinguished in the rain sensor control module:
1. The front windscreen wiper does not leave the parking position when activated. If the windscreen wiper does not move despite the appropriate power supply, actuation of the wind-screen wiper motor is interrupted after 3 seconds.
2. The front windscreen wiper locks after leaving the parking position.
- In both cases all operating modes are blocked after a motor block. The system can only be reactivated after the steering column switch has returned to the >OFF< position.
- If one of these faults is present, replace the rain sensor control module.
