Rain sensor (AIC): Diverse malfunctions
E38, E39, E46
Complaint:
The following malfunctions are known in the windscreen wiper control with activated rain
sensor (Automatic Interval Control / AIC):
1.
The windscreen wiper wipes continuously or in an uncontrolled fashion. This
malfunction occurs sporadically.
2.
The sensitivity of the rain sensor cannot be adjusted.
3.
Control of the windscreen wiper via the rain sensor fails intermittently. The control
works again properly after switching the ignition (terminal 15) off and back on again.
4.
The windscreen wiper remains off for a brief period of time when it is switched down
from normal wiper speed (wiper switch position 2 or 3) to rain sensor (wiper switch
position 1).
5.
The windscreen wiper switches on without reason when the vehicle moves between
shade and sunlight (e.g. when driving out of a tunnel into the sun).
6.
The windscreen wiper wipes the windscreen four or five times when the rain sensor is
activated. After this, the rain sensor control of the windscreen wiper no longer works.
7.
The windscreen wiper does not stop in the end position but rather it moves approx. 10
°
to 15
°
from this position and then stops.
If the rain sensor fails, the windscreen wiper control will operate in the same way as on a
vehicle without rain sensor installed, i.e. in normal intermittent wipe mode.
Cause:
Possible cause for fault patterns 1 to 5:
Software errors in rain sensor
Possible cause for fault patterns 6 to 7:
Windscreen wiper double relay defective.
Note:
Bubbles forming in the area of the rain sensor are permissible and do not as a rule affect
the functionality of the rain sensor.
Affected vehicles:
E38, E39, E46 with rain sensor
Manufacturing period: Start of series production until January 2000.
Depending on the model concerned, the rain sensor is available as an option in its own
right or in conjunction with other options, as follows:
- Option 500 "Headlight cleaning"
- Option 521 "Rain sensor"
- Option 978 "Innovation package"
- Option 970 "Business package"
Procedure:
In case of customer complaint, the software status should be determined and the rain
sensor fault memory read off with either DIS or MoDiC.
Concerning fault patterns 1 to 5:
If the rain sensor is programmed with software version 1.3 or earlier, it should be replaced.
