Windscreen Wiper Anti-blocking Function

The windscreen wiper anti-blocking function is integrated into the electronics of the wiper motor. If the wiper motor is obstructed, the electronics cease the actuation of the motor. The electronics communicate this via the LIN bus the next time the junction box electronics query the status.

A further attempt can be made to switch on the wiper. If the wiper blocks again, it will no longer be operative for approximately 3 minutes.

The wiper interlock is cancelled when the status is switched from "terminal R ON" to "terminal R OFF". The wiper must then be switched on again.
