Rear Window Wiping When Reverse Gear is Engaged

The rear window wiping in reverse gear works when the windshield wiping - reverse gear function is activated. This provides the driver with a clear view when driving in reverse.

For a detailed explanation of the windshield wiper function with and without a rain/light recognition sensor, refer to => [ Windshield Wipers without Rain Sensor ] Windshield Wipers Without Rain Sensor and to => [ Windshield Wipers with Rain Sensor ] Windshield Wipers With Rain Sensor.

• The windshield wiping information is sent from the steering column electronic systems control module to the vehicle electrical system control module via the CAN-bus Comfort.

• If the windshield wiping function is automatically sent via the rain/light recognition sensor, the vehicle electrical system control module will evaluate the current wiping status via the LIN-bus to determine if the wiper is working at that moment.

• If the vehicle has a manual transmission, the vehicle electrical system control module receives the information directly from the transmission range gear recognition switch. If the vehicle has an automatic transmission, the vehicle electrical system control module receives this information from the transmission control module via the CAN-bus.

• When reverse gear is engaged for a defined time, the vehicle electrical system control module will turn on the rear window wiper motor. The rear window wiper motor will work in regular intervals as along as reverse gear is engaged.
