Safety function
WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2006 BMW Z4, 2006 BMW M3, 2006 BMW M Roadster, 2006 BMW M Coupe, and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.
The signal from the reset contact on the wiper motor (also the rear window wiper on the E61) is used as an anti-jamming function for the wiper motor. If the signal from the resetting switch is not present when the wiper motor is switched on, the wiper motor is switched off again.
The wiper motor can then only be switched on one more time.
After that, the wiper motor can only be switched on subject to the following conditions:
- 3 minutes have elapsed
- Terminal R OFF followed by Terminal R ON
The wiper motor can only be switched on by operating the wiper switch (not automatically due to risk of injury).
Once the anti-jamming function has been activated, the windscreen-washer and headlamp-washer pumps can be operated 3 more times.
