Windshield Wipers without Rain Sensor

General Information and Components

• Wiper Motor Control Module (J400)

• Vehicle Electrical System Control Module (J519)

• Steering Column Electronic Systems Control Module (J527)

• Front Hood Switch (F266)

Function





The steering column electronic systems control module reads the position of the windshield wiper/washer intermittent switch. The following switch positions are possible:

• Interval Wiping

• Slow or Fast Wiping

• One-Touch Wiping

The steering column electronic systems control module the windshield wiping information to the vehicle electrical system control module via the CAN-bus Comfort. The vehicle electrical system control module (master control module) sends the information to the windshield wiper motor control module (LIN slave control module). The windshield wiper motor control module then starts the wiping action.

Service Information

The wipers must be in the Service position in order to replace the wiper blades. Refer to the Owner's Manual. This is also possible using the Car menu in the MMI.

Opening the hood will immediately stop the windshield wipers. If the hood contact should be faulty, the windshield wipers will work while the vehicle is moving (emergency wiping).

As soon as the ignition is turned off, the windshield wiper/washer intermittent switch will stop and the wipers will go back to the 0 position.
