5 Series E60 525xd (M57T2) SAL
Headlamp washer system (option 502)
When the dipped headlights are switched on, the headlamps are washed every 10th time the windscreen
washer is operated.
After ignition ON and dipped beam headlights ON:
The headlamps are cleaned at the same time as the first wash movement for the windscreen.
Wash-cycle sequence:
•
0.7 seconds ON
•
1.3 seconds OFF
•
0.7 seconds ON
After the headlamps have been washed, they cannot be washed again for another 10 minutes (repeat lock).
The repeat lock is reset by Terminal R status OFF.
Safety function
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.
