BMW 7 Series: Service Information
Wiper/washer System Emergency Operating Functions
Emergency Operation in the Event of the Steering Column Switch Cluster Failing
The wipers can no longer be operated in the event of the steering column switch cluster failing or a break in the bus connection.
The junction box electronics switch to emergency operating mode and the windscreen wipers are switched on in stage 1.
Emergency Operation if the Rain/lights/solar/condensation Sensor Fails
If there is a fault in the rain/lights/solar/condensation sensor or it fails completely, the junction box electronics take over control of the wiper/washer system and switch to emergency operating mode. Emergency operating mode is an intermittent wipe function that is dependent on the vehicle speed.
NOTE: The same applies if the rain/driving lights/solar sensor fails.
Replacement of the Rain/lights/solar/condensation Sensor
The following steps are necessary after replacing the sensor:
- Code the rain/lights/solar/condensation sensor
- Clear fault code memory
- Initialize the rain/lights/solar/condensation sensor.
NOTE: The same applies to the replacement of the rain/driving lights/solar sensor.
Replacement of the Wiper Motor
The wiper motor is connected to the LIN bus and this must be taken into consideration during the service.
NOTE: The Repair Instructions must be observed when the wiper motor is replaced. If the LIN bus fails, the wiper will go into emergency operation.
Replacing the Wiper Blades
The wiper arms can be moved to a service position in order to replace the wiper blades. This makes the wiper blades easily accessible and allows them to be replaced.
Activating the service position
- Switch on the ignition with the START/STOP button
- Switch off the ignition with the START/STOP button
- Operate the wiper switch on the steering column stalk (push it upwards and hold it there for more than three seconds).
The wiper arms now move into the service position (the upper reversal position of the wiper blades) and the wiper blades can be replaced.
