panied by periodic clicking sound
from the relay).
If the turn indicator lamp blinks and the
blinker relay clicks faster than normal,
then one of the turning indicators has
burned out.462de212

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically – the driver
does not have to perform any extra op-
erations or adjustments.
The indicator lamps also come on briefly
after the ignition has been turned on.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sunroof, etc.) is constantly ana-
lyzed by current measurements in their
relays. 462de258
In the same manner, the electrical resis-
tance of the airbag ignition generators
and all of the remaining airbag compo-
nents is measured at all times. Any fault
in this system would be detected imme-
diately by a current fluctuation that
would necessarily accompany it. The
fault would be indicated immediately by
the airbag warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation sys-
tem travel to the nearest limit position.
This action ensures that the system will
be able to provide defrosting, regard-
less of other circumstances (if a mal-
function in the heating or ventilation
system should occur during the night
while the vehicle is parked, for in-
stance).
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to en-
sure that appropriate adjustments for
the operating elements can be made at
any time.You will hear the sounds of the air flaps
as the heater/ventilation system carries
out its self-diagnostic functions after
the ignition is shut off. All of the other
self-diagnostics functions operate si-
lently in the background.
Any faults detected during these self-
diagnostics can be read out by your
authorized BMW center during the next
regularly-scheduled maintenance and
corrected with a minimum of time.
